The best time to buy bitcoin was when it was released

The second best time was a few years ago when it was only like $200/btc

The third best time was probably last year before they went up 650% in value

The worst time is apparently whenever I buy in

Dev Duck and Stress Ball joining me on crypto market watch!

Dear Telegram, the fact that you're using a service which provides app usage/metrics/analytics kind of is not nice.

"But they've got the right to!"

Of course they do. But, when you advertise yourself as a messaging app focused on privacy, I expect you to behave that way.

And yes, we know your crypto is broken as fuck but that's not the point right now.

Oh and yeah, the next blog item will probably be about Telegram and how not-privacy friendly it is.

It's funny to see how a coworker of mine and me are very similar minded on some privacy stuff. He's a very cool/open guy and just a regular consumer (used the default services etc) but he shares quite some of my views. This is a convo we had today:

*got to the WhatsApp subject somehow*
Him: oh right, you didn't use that haha
Me: yeah 😅
Him: why was that again, privacy reasons or something, right? xD
Me: uhm yes *help*
Him: Well fair enough.
Me: so you'd think I'm right? I mean it uses end to end crypto... (I'm entirely with him in the next few lines but I always approach it carefully)
Him: they veeeery probably have some kinda fucking masterkey.
Me: why'd you think that?
Him: it has over a billion users, the owner is facebook, fb is directly integrated with several mass surveillance programs, they are known to work closely with one particular one, the intelligence interests are way too high for letting such an opportunity pass and after all, THE FUCKER IS CLOSED SOURCE AKA NO ONE CAN FUCKING VERIFY THE CRYPTO NOR THE APP ITSELF.
Me: I agree haha 😅
Him: it's not rocket science, it's modern day mass tracking/surveillance logic :)

I like that guy.

Oh fuck and boy Jesus, how on earth is this still a thing 😦

MD fucking 5 is not a fucking “secure” crypto algorithm.

This site has 14 million breached accounts with fucking MD5 hashes.

I think I’ve had to much internet for today.

These fuckface wantrapeneurs, posting jobs (paying to do so) and then offering bullshit like:
- We have no funding, so you'll work for free for some time.
- Paying in fucking crypto.
- Wanting a full stack rainbow puking and shitting unicorn for peanuts
- Fucking scammers, posing as legit companies and asking you to install Anydesk.
- Asking absurd interview tasks and times (a couple of days worth of work for a task).
- Whiteboard and live coding interviews with bullshit questions thinking they're Google, while having 20 devs.
- Negotiating salaries and when presented with contract get the salary reduced by double the amount.
- Having idiotic shit on their company websites like a fucking dog as a team member associated as happiness asshole. (One idiot even had a labrador during the video interview while cuddling him)
- Companies asking you to install tracking software with cam recording to keep you in check. (Yeah, you can go fuck yourselves)
- Having absurd compensation schemes, like pay calculation based on the "impact" your work has

Either I'm unlucky or job hunting has become something else since I last started searching.

Following a conversation with a fellow devRanter this came to my mind ago, happened a year or two ago I think.

Was searching for an online note taking app which also provided open source end to end encryption.

After searching for a while I found something that looked alright (do not remember the URL/site too badly). They used pretty good open source JS crypto libraries so it seemed very good!

Then I noticed that the site itself did NOT ran SSL (putting the https:// in front of the site name resulted in site not found or something similar).

Went to the Q/A section because that's really weird.

Saw the answer to that question:

"Since the notes are end to end encrypted client side anyways, we don't see the point in adding SSL. It's secure enough this way".

😵

I emailed them right away explaing that any party inbetween their server(s) and the browser could do anything with the request (includingt the cryptographic JS code) so they should start going onto SSL very very fast.

Too badly I never received a reply.

People, if you ever work with client side crypto, ALWAYS use SSL. Also with valid certs!

The NSA for example has this thing known as the 'Quantum Insert' attack which they can deploy worldwide which basically is an attack where they detect requests being made to servers and reply quickly with their own version of that code which is very probably backdoored.

This attack cannot be performed if you use SSL! (of course only if they don't have your private keys but lets assume that for now)
Luckily Fox-IT (formerly Dutch cyber security company) wrote a Snort (Intrustion Detection System) module for detecting this attack.

Anyways, Always use SSL if you do anything at all with crypto/sensitive data! Actually, always use it but at the very LEAST really do it when you process the mentioned above!

Banks be like

You don't have much money?
Here, let me keep taking some of that from you until you get more, k?

Oh, that was more than you had?
Now you owe me even more, nerd.

What, you can't pay that either?
Better ask me for a loan so you can pay off your debt to me. Loser.

What? You still can't pay?
I'm gonna take your everything!

Hey devRanters! A tiny update regarding the privacy tips etc site.

So as ewpratten doesn't have much time right now, I'm doing frontend as well for now.

Since some people also offered to contribute content, which I did not expect, I am also writing an invite/registration (based on invites) as we speak. So, this way, I can invite anyone (based on email address) into the CMS so that they can contribute content as well!

Regarding frontend, I'm introducing a system with icons. Icons? Yes, icons, let me explain:

Every application/service will get a couple of default filtering thingies. (not like clicking something and it'll filter anything out, yet) It'll enable users to see what an application does or does not. What the FUCK do you mean? Alright, so, as example, lets say open source. next to each application (read application/service) listed, there will be an open source icon. If the application is open source, this icon will be green, otherwise it will be red.

This will allow for a quick way of filtering stuff out.

For example, if you're only looking for open source stuff, you can quickly filter stuff out where the open source icon is red!

This will apply to things as open sourceness, metadata saving, usage of good crypto technology and so on. So you'll be able to quickly filter out the stuff you want to use (by eyes) through those filters!

Please let me know what you think and if you have ideas, I'll be glad to hear them!

The coolest project I've worked on was for a certain country's Navy. The project itself was cool and I'll talk about it below but first, even cooler than the project was the place were I worked on it.

I would go to this island off the coast where the navy had its armoury. Then to get into the armoury I'd go through this huge tunnel excavated in solid rock.

Finally, once inside I would have to go thru the thickest metal doors you've ever seen to get to crypto room, which was a tiny room with a bunch of really old men - cryptographers - scribbling math formulae all day long.

I can't give a lot of technical details on the project for security reasons but basically it was a bootable CD with a custom Linux distro on it. Upon booting up the system would connect to the Internet looking for other nodes (other systems booted with that CD). The systems would find each other and essentially create an ad-hoc "dark net".

The scenario was that some foreign force would have occupied the country and either destroyed or taken control of the Navy systems. In this case, some key people would boot these CDs in some PC somewhere not under foreign control (and off the navy grounds.) This would supposedly allow them to establish secure communications between surviving officers. There is a lot more to it but that's a good harmless outline.

As a bonus, I got to tour an active aircraft carrier :)

One of my favourite, encryption puzzles is this:

ITuyVT93oUZtLKWyVT5iqPO3nTS0VUEbMKxtp2IyoD==

Answer is plain text string in english. Good luck, post solution in the comments!

What I'm posting here is my 'manifesto'/the things I stand for. You may like it, you may hate it, you may comment but this is what I stand for.

What are the basic principles of life? one of them is sharing, so why stop at software/computers?
I think we should share our software, make it better together and don't put restrictions onto it. Everyone should be able to contribute their part and we should make it better together. Of course, we have to make money but I think that there is a very good way in making money through OSS.

Next to that, since the Snowden releases from 2013, it has come clear that the NSA (and other intelligence agencies) will try everything to get into anyone's messages, devices, systems and so on. That's simply NOT okay.
Our devices should be OUR devices. No agency should be allowed to warrantless bypass our systems/messages security/encryptions for the sake of whatever 'national security' bullshit. Even a former NSA semi-director traveled to the UK to oppose mass surveillance/mass govt. hacking because he, himself, said that it doesn't work.

We should be able to communicate freely without spying. Without the feeling that we are being watched. Too badly, the intelligence agencies of today do not want us to do this and this is why mass surveillance/gag orders (companies having to reveal their users' information without being allowed to alert their users about this) are in place but I think that this is absolutely wrong. When we use end to end encrypted communications, we simply defend ourselves against this non-ethical form of spying.
I'm a heavy Signal (and since a few days also Riot.IM (matrix protocol) (Riot.IM with end to end crypto enabled)), Tutanota (encrypted email) and Linux user because I believe that only those measures (open source, reliable crypto) will protect against all the mass spying we face today.
The applications/services I strongly oppose are stuff like WhatsApp (yes, encryted messages but the metadata is readily available and it's closed source), skype, gmail, outlook and so on and on and on.

I think that we should OWN our OWN data, communications, browsing stuffs, operating systems, softwares and so on.

This was my rant.

I don't need anything else!

The ultimate "I am vegan" guy will be arch linux user, vegan, trans, crossfitter and cryptocurrency investor. I've just met guy like this in my job. He did not shut up for a while. I am not sure whats he doing and whats his job but my guess is that hes paid for spreading cancer, sucidal toughts and eatig your will to live and talk with people...

R - retard
M - me

R: Hey CopyPasteCode I found this bug, it does 'this' insted of 'this'. *spreads arms to see his "muscles"*
M: *headphones off* Ok, I will look into it... *headphones back on*
R: Btw you invested something in the crypto, didnt you? Ive invested... ...bitcoin... ...crypto... ...litecoin..., do you think that... ...something... ...bla bla bla?
M: *tries not to kill myself after his 5 minutes of monolog* Ye sure
R: By the way Ive found this awesome vegan restaurant that accepts litecoin, would you like to come sometime?
M: *10 minutes monolog about vegan food and shit. At this point I want to die* Ok, I will now work on that back, see you later.
R: ye sure bro (wtf, "bro"?)... *looks like hes walking away* *teleports on my otger side touching my monitor*
WOW you are also a Limux user? 😮 Ivr installed arch linux this weekand and its so awesome, *another 6 minutes of monolog*
M: *smiling and preparing to kill him or myself* Nice, awesome *fake smile*
R: Anyway, I gotta go (FINALLY!!!), btw, I am going to the *name of local trans and gay club*, wanna go with me?
M: *after a month after a breakup with my GF (because she was cheating on me) which everyone in the office knew...)* Not really *trying to thing how to say "fuck off" without having meeting with HR*, I cant, I already have somethimg.
R: Oh, ok. Btw, you are rly cool bro (again), we should hang. We should hangout more often...

I hope someone is paying me for loosing 27 minutes with this guy.

My next project is creating a genetic algorithm that can play with crypto currencies for me.

I shouldn't have told my family. They think i'm going to be sharing the money now 🙃

The company i work for has a jenkins server (for people that don't know jenkins, it's an automated build service that gets the latest git updates, pulls them and then builds, tests and deploys it)

Because it builds the software, people were scared to update it so we were running version 1.x for a long time, even when an exploit was found... Ooh boy did they learn from that...

The jenkins server had a hidden crypto miner running for about 5 days...

I don't know why we don't have detectors for that stuff... (like cpu load being high for 15 minutes)

I even tried to strengthen our security... You know basic stuff LIKE NOT SAVING PASSWORDS TO A GOOGLE SPREADSHEET! 😠

But they shoved it asside because they didn't have time... I tried multiple times but in the end i just gave up...

Would the web be better off, if there was zero frontend scripting? There would be HTML5 video/audio, but zero client side JS.

Browsers wouldn't understand script tags, they wouldn't have javascript engines, and they wouldn't have to worry about new standards and deprecations.

Browsers would be MUCH more secure, and use way less memory and CPU resources.

What would we really be missing?

If you build less bloated pages, you would not really need ajax calls, page reloads would be cheap. Animated menus do not add anything functionally, and could be done using css as well. Complicated webapps... well maybe those should just be desktop/mobile apps.

Pages would contain less annoying elements, no tracking or crypto mining scripts, no mouse tracking, no exploitative spam alerts.

Why don't we just deprecate JS in the browser, completely?

I think it would be worth it.

SAVAGERY LEVEL: 10000

So I am running this crypto project that has dynamically generated private keys for a wallet stored in a Redis database. Nowhere else. The keys are generated on the fly.

At the moment of the happening the wallet had over 3.000 USD on it. I am testing new code locally, supposedly on a local Redis DB. Of a sudden, my code wipes the crypto keys and it turns out that I was connected to the live instance. 😱 Better don't ask me how.

Shock of my life. You know, when you turn pale and dark in your eyes, blood stops in your veins and you just want to die? Worst-case scenario that could have happened. All that money lost in crypto space.

Turns out, my good Redis hosting company kept backups for the past 7 days. Keys restored. Happiest moment of my life.

Downloaded Kubuntu because i couldn't seen to be able to boot from a freshly created KDE Neon bootable usb.

Installed it onto my netbook (Lenovo Thinkpad X121E) and it worked great!

But just the fact that somehow the installer froze when trying to setup hdd encryption kept bugging me.

Took a random flash drive which was laying around and put it in to see what would happen. KDE Neon booted just like this and everything worked very well with hdd encryption.

I now have a very secure netbook 😊

@dfox Thank you very very much for the duck. And biggest thanks goes to @olverine who actually bought the duck as a reward for solving his crypto challenge. Thank you guys

Had a final year project defence today in university. There were about 15 CS teachers in the room.
Our project was "Crypto Currency". After all the presentation was finish.

Teachers: so what is this blockchain?

** explained all about it and how it works with marker in a whiteboard **

While most of the projects were rejected and they have asked several cross questions to other friends, they didnt even ask any question to us and said our project is accepted.

Turns out teachers were taught by a student today, feels so good 😎 😂

Just saw this in the code I'm reviewing:

function encryptOTP(otp){
var enc = MD5(otp);
return enc;
}

Scrum:

Boss to designer: sadly the green logo was not chosen and we will go with the purple one.

D: oh good choice, but why green was discarded?

B: green is not enough criptocurrency related.

Me: in my mind: how a color is crypto related... What wut? Procceed to do weird faces, twitch and spasm while I try to sort this out.

Boss see me and beat me (gently!) with an inflatable chicken.

Guys. Green is not crypto.

So I host a few mining pools and some of the stories we hear from miners can be quite interesting. One of our miners recently had his front door busted off the hinges and a drug bust team go into his house and turn the house upside down. How did they determine that he was a threat for growing illegal drugs? Well he had a high power bill because of the miners and he grows flowers and food inside of his house and that was enough for THE NYPD to get a warrant.

Now he is responsible for cleaning up the mess the police made. What scares me the most is that they are tracking soil you buy online along with high power bills. What the hell USA im a proud Canadian

Why do so many people waste their time and their computers turning coal into heat? It really pisses me off.

Often I meet smart guys who are fairly decent coders and after what starts as an interesting conversation is instantly destroyed by cryptocurrency.

It is *exactly* like enjoying a discussion of the intriguing nuances of quantum chemistry only to have the guy say, "thats all cool, but how do you make meth?"

argh.

You want to use your decked out rig to make money? Fine. But please help us solve important problems instead of literally wasting electricity. Just google search "supercomputer physics" and you will find a thousand current problems requiring extremely fast computers for number crunching. All of them can make you more money than crypto and all of them help society at the same time.

We burn coal to make most of the electricity on this planet. Most coal stations burn around 20,000 tons of coal per day. The world burns about 250 tons of coal every *second*. This is converted into carbon dioxide. (coal = carbon, add two oxygens when you burn it, producing three times as much mass in CO2, which then goes out the smoke stack)

The big picture is this: currently we are forced to burn coal to make the world work. Turning off the boilers would result in an almost instant apocalyptic collapse of society. BUT, we don't need to burn it merely to produce waste heat in your video card array.

Please use your superpowers for good.

<end rant>

There's this TV show called Startup. The protagonist "hacker" tells a guy to go learn JavaScript. And then they show him learning Java. If noobs make this mistake, I get it. But a TV show that's featuring a "hacker" who can create crypto currency and dark web sites? WTF?

When you reboot your server and on boot it asks for the hdd encrypted password. I have no clue anymore. Oh how fucking happy I am that we have no users yet and are in closed alpha. Happy to learn this now so I'll never make this mistake again. 😨

golang is so beautiful.

standard crypto library, compiles natively, pointers, it's pretty cool.

👍

Case 1 - You sold the coins. And price continue to increase

Case. - Even when the coin reached it peak, you just hold the coins, because you learned something from Case 1. Eventually coin collapse.

And this continues in loop

Hackathon rant.
So I had my first hackathon ever.
It was about co2 reduction which is pretty neat but our team leader had a different view on this. He only saw money in his idea so we build a smart energy meter that advised the user on how he should control his energy. And if the user had solarpanels or something his overtake of energy would be converted into a crypto currency and transferred by our Blockchain system.

The idea is pretty cool but it had no real co2 reduction and way too customer based. Which kinda sucked for my first hackathon but our business guy gave a amazing overwhelming pitch about stuff we didn't make at all. And somehow we ended up on the third place yay

If anyone wants to take the recent crypto currency obsession to the next level, here you go lol

Im so frustrated with myself . I've always been afraid of being stupid . Perhaps it was because i was always called the "less intelligent" sibling by my parents . Well i did self-learn java , c++ and android (when i was 15) and made some apps and i did get acknowledged finally but i may have not acknowledged myself . I got into college a couple years ago and i can tell you right out that its like an island filled with stupidity. The teachers , the students. The other day i caught my teacher learning how a transistor works. This is unacceptable for someone who is teaching us advanced op-amps and other circuits . Well , I did get into this college cause it was less tedious and i thought college doesn't matter cause i can self-learn . All i needed was free time . Well college totally destroyed that too and provided no facilities in the process as well . So yeah should i blame my college for my inability to do things the past couple years. I mean i don't think i've learnt a single thing all this while. This is where my frustration begins cause i dont want to blame the college , it's not going to help me and i'll probably end up in a 9 to 5 call center job at this rate . Im also very heavily frustrated with myself , it's like everything i've done so far has been a path of least effort. I have tried a few things which were all just fads like machine learning and crypto and even trading . They felt good and thats what scares me , maybe i don't have the passion and am just looking for a quick buck . This is clearly reflected in the ideas i've been having as well . Well i've never had access to proper funds but now im just trying to justify this layman emotion . I just want to learn and be passionate about learning , researching and i just want enough funds for that . But im afraid , maybe its just that i want to feel superior than my circle . I mean i still don't know why i tried learning rust and wasted even more time setting up fedora and everything around it while i already had a working debian setup and a programming language i'm kind of versed with . i wouldn't say well cause im a self learner and i feel guilty for that . I definitely know i just learnt the surface of the language . Deep down i'm just another stupid fad obsessed guy who feels better by choosing a more complex language that my colleagues look upto . Is this what i am , if so im scared and i don't know what to do . People say that you are what you are and you cant change that . If i cant change this then i dont deserve this wasteful stupid life . I don't know what i should do and it makes me cry . Maybe acknowledging this would've helped but it hasn't , I've felt better playing fortnite rather than learning some basic electronics. Im another one of those aren't I ?

Ok fellow ranters. I've scoured the internet for hilarious and enraging stories of programmers being asked to either work for free, or for stock options, or to hack (crack) stuff, etc.

Here's my latest one. A friend who's obsessed with crypto came up with a "great" idea which was for me (of course) to build a landing page for a fake company to trick people into submitting their crypto wallet keys and all that. What started as a joke quickly turned into my friend getting mad at me for not wanting to actually make it lol. Like seriously wtf is with people. All the reasons not to do that scheme are plainly obvious!

Next. Some person who worked for a company I consult with pulled the generic. "I have this great app idea" line & proceeded to of course ask me to "not steal it" lol. It was just an app that would list gluten free restaurants... That's hardly even an idea!!

But what's fucked up about all this is my friend from the first story is so obsessed with becoming a "crypto millionaire" he actually resents me now for not
1. being obsessed with crypto
2. not committing cybercrime on his behalf

Anybody else have enraging stories about stuff people have asked you to do?

Anybody else feel like you've missed the crypto-currency bus?

It's one of my frequent regrets this past year, and I'm still figuring out how to get started earning some BTC.

Fuck this, fuck that, fuck the buffer, fuck AES, fuck crypto, fuck node-forge, fuck IV and browsers, once I am done with this fucking cryptographic wrapper on both client and server, the first person to say decrypt and Javascript in the same sentence in front of me will get their own dick in their ass. The guy that said mixing computer and crypto was a bad idea was fucking right

So it seems like Github banned a lot of Iranian accounts and repos. Clearly, enriched uranium is stored there.

I got a kindle paper as a hand me down gift. And I feel I'm reading so much more than before, now!

I'm starting a new small novel
A Wrinkle in Time, I'll be reading alongside my girlfriend.

I'm 52% done with a book called
Python Tricks: The Book
Literally coolest book I've touched. Contains a bunch of different tidbits about the language, granted most of them confirmed my understanding, but it's still neat to read and learn about them in a more rigorous setting.

I'm 13% done with another book called
How to Day Trade for a Living
I'm heading for the crypto currency exchange, but with a catch,
I'm reading another book called
Genetic Algorithms with Python
You can probably already guess where I'm heading.

I feel armed with more knowledge and I feel like this is a really great way to start the New Year off.

Tried mining ethereum today. Just wanted to check that out, for the heck of it. Fired off a p3.16xlarge instance on AWS, 4 x Tesla V100 running at $12 an hour! It was an absolute beast. Anyway, kept it running for 9 hours and earned about $5 before shutting it down. Cost me $108 to earn that $5. Had a lot of credits expiring in a couple of days, so I wanted to burn them off anyway.

So crypto mining, not easy money.

Have you heard that Facebook is developing a cryptocurrency?

Huge waste of money. Everyone knows Facebooks security flaws and will problably not invest in their cryptocurrency because of that.

I feel like I've ranted this before. many times. but here we go again because Australia.

why do people think you can just ban math? like really?! that's what crypto laws do. they require companies to use shitty math. and what prevents me from using the good math? nothing! oh I mean... I won't use it? scouts honor.

you can't ban math.
literally billions of internet users don't fall in your jurisdiction.
no single jurisdiction can cover more than a subset of the internet.
I will use whatever maths I damn well please.
fuck off. please stop making us less safe.

Heey, it's me, D3add3d! As you might remember there was a crypto riddle posted by @Kimmax approx. a month ago. Now I'm here with another crypto riddle, it should be fairly easy one. The previous riddle was based on PGP so no rotation of alphabet was involved.

Here is the riddle:

Got the book ^ ^
Feel free to comment any cool book about security :)

Recently at my work everyone got all hyped about blockchain. I've spent years studying it and especially crypto so I like to think I know a lot about it. Now every time some feature is discussed (like tracking video views) someone non tech shouts out "Oh we can use a blockchain!" And I have to spend half an hour convincing them why it's a bad idea in this particular case. Like we don't need to share that data, we don't need to ensure integrity without trust etc. I mean a blockchain is a great piece of tech but please stop trying to apply it everywhere...

It's like people think that the blockchain features at its most simplified level don't work anywhere else. E.g. as if stuff you put into MySQL suddenly changes because data integrity is not a 'feature' in that sense...

I noticed the main dogecoin repo was one star short of a significant milestone. Is it odd to feel honoured to be their 2000th?

Just in case you didn’t buy into the crypto trend. Maybe this will make your week better.

well, I'm atheist. but I approve. ;-)

WARNING: I am a n00b at this crypto shit!

I’m working on a personal project on React Native to learn how to work with, basically it’s a mobile interface to interact with crypto exchanges through their APIs to centralise everything on this app.
This morning I got a personal message from twitter that asked me:
🙍‍♀️When will this be done?
🙎🏻‍♂️I will work on this during my days off next week
🙍‍♀️You should add a feature that let people know in which exchange a coin is cheaper
🙎🏻‍♂️It’s a good idea but there’s so many parameters such fees to take in account there’s no correct estimations
🙍‍♀️Leave out the fees
🙎🏻‍♂️Fees are important, people have few money to invest normally
🙍‍♀️What about getting posts from cryptoblogs and putting them in a feed?
🙎🏻‍♂️That’s exactly what Blockfolio does. I see you have a lot of ideas and I appreciate the input but what is your point here?
🙍‍♀️I want an app that tracks lowest prices and has a feed with my blog posts. Will you work for me? There will be no way to monetise first months.
🙎🏻‍♂️...
I guess I’ll never answer her. Like trying to turn MY app to HER app and then ask for free work. Bye baby!

Apple: "We're justified in taking 30% of all our customer's in-app purchasing revenue because we've implemented an awesome super-secure in-app payment system"
Me, after spending the last week wrestling with Apple's shitty, horrible, unbelievably obtuse, poorly documented system for handling subscription renewals and having to write my own god damn crypto shite for reading receipts: "You're shitting me, right?"

What a complete scam.

In an encryption-module, I had a bug, that caused my PC to crash, every time I tried to encrypt something.
Turns out, the loop, that appends
0-Bytes to the string, to make it Block-Cipher compatible,
Had an logical-bug in its exit-condition, that caused it to run infinitely and allocate an infinite amount of memory.

“Crypto currency bank” are you serious?

WHAT THE FUCKING SHIT DO YOU WANT FROM ME??! I LITERALLY GET SPAM MAILS EVERY 5 MINUTES (i know I know, some of you get more than that) ABOUT BITCOIN. I NEVER DID ANYTHING FUCKING RELATED TO CRYPTO CURRENCY! HOW DO YOU KNOW MY EMAIL?? LIKE WTF. I'm sitting here doing my stuff and every few minutes my phone starts ringing and I'm like "hey maybe person x answered or something else important happened" but when I actually look at it to see whats up it's just a fucking email about bitcoin being outdated and it tells me to maybe invest into other crypto currencies. After actually reading one of the spam mails because I was interested in what they actually want from me I had to find out that they do not even mention any other currency or website. WTF INTERNET?? WHAT DO YOU WANT?

BTC passes 7k$ be like 🎉🎉🎉🎊

NODE CRYPTO YOU PUSS RIDDEN CANCEROUS CYST ON THE SWEATY BALLSACK OF THE INTERNET... fucking explain to me how every mother fucking module in node with require(‘crypto’) in it throws a hissy fit at runtime when I call only 1 file with it in it?! These packages that I’m not fucking using by the way but are nonetheless included by default in node are the ones having a meltdown.. and nodes answer?! Use the embedded functions. WHAT THE ACTUAL FUCK?!! If I didn’t need it Node could go and get gang raped by an angry pack of silverback gorillas. Fuuuuuuucccckkkkk yoouuuuu

so uhh, i asked a question on the crypto stack exchange, and it got -1 score, but 1 favorite.

Ok so I have done some work with crypto currency mining pools and recently a client requested for me to make a splash page that showed data from multiple instances of these pools APIs. I went to find some documentation for this open source api and to my surprise there is none. I thought of querying the public API from the clients side and it worked, however it's so slow that the data shows up roughly 20 seconds after the page loads.

Easy fix right? Make a PHP server get the data every 5 seconds, cache it and serve the data with the page and use a websocket for live updates! Until I found out that there is no practical way in this garbage framework to get the damn API data without making an HTTP request or mutilating the original source code. I'm so done with this garbage framework. It literally loads pages based on a page and action parameter on the index.php. I quit.

In 2018 everyone wanted to be in crypto. In 2019, we will find out who really wants to be in crypto. 💸💸💰

A few days ago our server was compromised due to an outdated Jenkins version. The malicious user installed a crypto miner on the server... The same day that it was found I told management that I'm interested in helping out with the server. Since then, nothing happened... No updates, no security measures, no nothing (except for the removed crypto miner and updated Jenkins software)

Oh well only a matter of time before another hack...

Question to some (who work way way way longer than me) med - seniors, should I make a big deal out of this? And keep pressure on it. Or should I just leave it be and wait for the next comprised server? I know devrant is not a Q&A service, but some dev to dev advice is much appreciated.

- incognito

I cant wait for edgey hipster SoDev students to start talking to me about underground git repositories that they use. Although, at least they'll stop talking to me about ML, NN, and crypto.

My father is very interested in stocks and thus he has also heard of crypto currencies. He just asked me if I could setup a Bitcoin wallet and if I know more stuff about crypto currencies.

I myself know a bit about these things so any tips for starters? 😄

Really? Why?

!dev

Sorry if this is a bad read, pretty new to devRant and writing in general.

I can't help but think and think of how much I fucked up my opportunities to completely change my life/financial status a couple of times. Damn.

A few years back (it was 2009, I think) I was playing Diablo II online, helped some random guy get through the hard levels. Normally, in such situation the lower lvl player allowed the higher level guy to grab the valuable boss loot; however this time the guy except sharing the loot with me asked me if I want his spare 2000 bitcoin. I asked if it's of any value, he said "not really".

I said I'd contact him later, when I figure out how this thing works and how to setup a wallet.

Guess what, I was too lazy and forgot about this thing completely. Then we lost contact.

In 2010, I made a comeback to bitcoin, but instead of buying it, I downloaded the bitcoin client, the blockchain (it was 800 mb in size, I remember) and have been contributing by running it on my PC for like a year.

Finally decided to get it ~3 years ago. Bought 2.5 BTC for 400$.

Was holding it, until I fell for the "free OmniseGO" scam and somebody stole them off me.

All of these can't get out of my head.
I visit coinmarketcap literally every hour to see how much I could have now. My girlfriend, friends, family, all fail to cheer me up. I still made a pretty good deal buying 5.5 ETH for 45$ and thats like 2500$ soon, its nice but this much I can make by coding

Shit, what do I do to stop being stressed except for seeing a psychologist.

May my failure make you smile today

Not sure if this is progress or what... But the people who asked me to fix their laptops or build their website now want me to help them out in starting their very own crypto currency.

What's your best crypto Pickup line?

Wow just realized Simpsons had an episode on crypto... all the way back in February.

If only the the MVC would actually mail me my new drivers license that I renewed almost 6 months ago... I could actually buy some... (exchanges require ID verification, so much for anonymity ¯\_(ツ)_/¯)

I'm going through a KhanAcademy course learning about cryptography. I learn better by doing, so I wrote a script. It shifts bytes up depending on a random int produced by a high entropy pseudo random number generator using a sha256 hash as the seed. I'm trying to find information on the flaws with this method, that lead us to create DES, and then AES.

Buying CryptoKitties at work. Teamed up with my boss and some collegues. I love this workplace 😄

For those of you who are riding the crypto currency train I have a question. I'm looking to colocate a few antminer s9s and I'm unsure how to verify that the cooling will be adequate.

What is the best way to verify this?

Community that link between experts and new traders to exchange signals in the crypto-currency trading world

Finally a good usage of all these buzzwords

Me to Me - I will Buy 1 Ethereum after Exams ( 8th Dec )

After Exam -
I will buy it soon.

Today -
Ethereum touched $700

Sometimes I commit fixes for issues on my crypto exchange api repos without testing them and tell the issue author to test it themselves because "I don't have api keys for the respective api" to test it.

I'm fully registered on every exchange from here to Japan. 🙄

Bad time is, when I buy crypto currency
But worst time is, when I sell it

When you need just simple plugin for the browser and what you get is a crypto miner fully utilizing single core :(

I hate people who own crypto and think they're some futurist tech elite. You don't know how the price will fluctuate in the future so stop thinking you're some goddamn fucking wizard. Just because you know the very basics of how a blockchain works or simple economics, doesn't mean you're better than those who don't own crypto.

What’s a good CryptoCurrency to start investing in and also what’s your preferred Exchange? 🤔

I don’t give a fuck about crypto currency, bitcoin and all the shit. I don’t even want to know how it works.

I’m an arrogant or dumb ??

Roast me.

Blockchain technology, looking forward to see what is really do!

I feel like premium content should be available via paid (ad-free), free (ads), or through web user small scale crypto mining, at the users discretion obviously.

I don't get why we have to have these ad blockers and ad creators trying to one up each other. The *option* for low-performance crypto mining while on the page would be cool to have as a choice.

Crypto currencies based on their usage

You guys believe in crypto currency in a near future to play a major role in our lives? Which one(s) you have?

!dev

Decided to spend more time on LinkedIn to familiarise myself and start looking for potential employment opportunities.

For past month or so, I've seen few decent opportunities, which is a nice start. However, for every decent post, I've come across:

- About a hundred of posts by self-proclaimed crypto experts who spout absolute gibberish and somehow get thousands of likes. 5 min google search and absolute minimum knowledge of economic theory discards 99% of their claims and statements
- Handful of idiotic "career advice" blog posts
- Numerous posts, both bashing and helplessly supporting shitty recruiter practices
- more crypto nonsense
- People jerking themselves off for running a profitable business (company launched a 1-5months ago)

Really starting to hate the platform, seems like all the integrity it had before becoming fully mainstream, has gone down the drain and it's become a straight up corporate circle jerk

Avoided IoT(IoS - InternetOfShit) for a long time now, due to the security concerns with retail products.
Now I looked into 433 Transceiver + Arduino solutions.. to build something myself, just for the lolz.

Theory:
Smallest Arduino I found has 32 KByte of programmable memory, a tiny tiny crypto library could take around 4 KBytes...

Set a symetric crypto key for each homebrewn device / sensor / etc, send the info and commands (with time of day as salt for example) encrypted between Server <-> IoT gadget, ciphertext would have checksum appended, magic and ciphertext length prepended.

Result:
Be safe from possible drive-by attacks, still have a somewhat reliable communication?!
Ofc passionate hackers would be still able to crack it, no doubt.

Question: Am I thinking too simple? Am I describing just the standard here?

Recently we started to encrypt all our PHP code.
To hide the code that we use to unauthorized people.

A new intern deleted ALL the encrypted and uncrypted files from all the servers (Also our backup server) saying
"I thought it was a Cryptolocker".

Now I can fucking start to find it all back and maybe even recreate our system and fucking crypt everything again.

What do you think about cryptocurrencies and Blockchain technology?

I'm most excited about Smart Contracts & Distributed Applications.

In early January I started learning Solidity thinking it would be super difficult but was pleasantly surprised when I'd completed my first DApp in a couple days. Two months on and I've finished 3 major projects and launched my own Udemy course.

I'm not a big follower of Crypto Currencies at all and haven't become financially invested in anything really. I just love the way development works on a blockchain; it is quite interesting and It feels really fresh solving problems using code that will become immutable.

TL;DR: Phone akku is draining, I steal our schools power. And secret plans to become rich.

My phone accumulator (heh, not a battery) DRAINS these days. It's fucking old and the temperatures are so hot that we actually afternoon classes are cancelled 🔥
So anyways, I'm sitting in the library (15 min break) and secretly charging my phone, devRanting on these wrongly configured, distorted monitors of this one computer that is connected with like 20 work stations xD
I'm stealing the schools power but the school owes me time (+2h of more useless sitting at school with my new timetable) - and time is money. And the schools money buys power. So I don't feel bad about it.
Actually a friend and me wanted to develop and install a plugin - when being able to bypass the reset-application in our school network - that uses the schools computers and their power to do crypto mining.
I wouldn't feel bad about it.

Where to begin learning about blockchain? (Google searches return way too much information.)

This has been in the back of my head for years now. And with all the attention that crypto currency has been getting lately, reminded me to look into this again.

Note: I don't actually care for cryto currencies, I'm just really curious about blockchain technology.

Disclaimer: This is all theoretical. Neither me nor my friend (with whom I discussed this) are stupid enough to even try to pursue this, but as an idea, i believe it might generate cool/new ideas/ways for handling secure communications across social groups.

Let's do some role play. Let's design a delivery app for drug dealers, think Seamless or Uber Eats, but for drugs. Not for big deliveries, like kilograms of coke, but smaller stuff. Maybe a few grams of it or something. The clients could rate dealers, and vide-versa. This would build a level of trust within the system. There would be no names, just anonymous reviews, ratings, and prices. Only the info you'd need to know.

The biggest (only?) problem we found (besides legality) was that, how would you prove that you're a client and not a snitch (or cop). This would have to somehow be handled both on signup, as well as when ordering (let's imagine that all who are clients are pure and won't ever snitch).

One of the ways we found to combat this was to have the app invite-only. This would, in theory, do away with the problem of having snitches signing up. However, what if the phone got stolen/breached by a snitch, and they also got full access to the account. One way we thought we could combat this would be with a "dispose number" or something similar. Basically, you call a number, or send a text, or message a Signal bot etc, which would lead to the account's instant termination, no traces of that user left. Hence, a dispose number.

The flow of the app would be as follows:
A client wants some amount of heroin. He opens the app, searches for a dealer, sends the him the desired amount, and in return gets back a price from the dealer. If both parties agree on the amount and price, the deal would start.

The app would then select a random time (taken from the client's selected timeframe and the dealer's "open" time) and a location (within a certain radius of both them, somewhere in between them both for convenience). If both of them accept the time and place, they'll have to meet up at said time and place.

The actual delivery could also be done using two dead drops - the client drops the money at one of them, the dealer drops the goods at the other one. Yes, this might be subject to abuse, but it wouldn't be that bad. I doubt that clients would make huge orders to unknown/badly rated dealers, as well as dealers accepting offers from badly rated clients. My idea is that they would start small, just so if they do lose their money/goods, the actual loss wouldn't be as big for them, but for the other party, having bad ratings would mean less clients willing to buy or dealers willing to sell.

A third way would be to use crypto, but the reason I left this as the last one is because it's not that wide-spread yet, at least not in local drug dealing. With this method, the client would initiate the order, the crypto would be sent to either the dealer or an escrow account, the dealer would then drop the goods at a random place and let the client know where to go to get them. After the client has gotten the goods, they could both review/rate the quality as well as the overall experience with that dealer, which would either make or break the dealer's upcoming deals. This would be pretty much like other DNM's, but on a local scale, making deliveries faster.

So far, this would seem like something that would work. Are there any ideas that might improve this? Anything that might make things more secure/anonymous?

My reason for this post is to spark a conversation about security and anonymity, not to endorse drugs or other illegal stuff.

Cheers!

PS. Really loving the new PC design of devRant

!dev, crypto related.

Crypto is a fucking cancerous community at the moment, where everyone thinks that he will get rich overnight or just by scratching his balls in front of his pc, full of pseudo traders that shill coins here and there, talk like they were Jesus and X currency was a religion.

People that have no sense of criticism, that invest in thing they don’t understand and all this “coins rivalries“ look more like a fucking competition between brotherhoods in college than sane competition between companies.

That said, people still understand cryptocurrencies as investment assets when they should be user as what they’re called: currencies (some exceptions apply, I.e. ICOs)
Still nobody at this price would use them to buy goods and services because “it should be worth XY” and that just to reconvert them to fiat.

On the top of that, Bitcoin was born to be anti banks, anti governments, anti 3rd party trust and of course this kind of freedom has been already suppressed.
And now the exact reverse concept appears: without government trust people won’t use them because they choose to be “legal” instead of free to do what they want by following a proper ethics (don’t buy drugs kids).

Finally, SEC pushing the decision about ETF has made people scary instead of confident because it’s the same kind of people that want to be rich overnight and didn’t think that pushing the deadline for decision is a good thing as that means that they really want to take in consideration what they’re doing and want to do things the right way. That said it still kills concept of no 3rd party.

At least the dumb money has got out, and well maybe see smart people get in.

I want an rx580 for my new pc build, but all of them are sold out...

Damn cryptominers, now I'm realy pissed!! 😠

Users complain about advertising and how it is annoying to have to see these ads just around the page while they just want to see the main content. So what do they do? They decide to use adblockers which start pushing web admins to find another method to make money. So half the time they offer the service for a lot more than normal which makes people not want to pay for it. So now I decide to push into the embedded crypto miners, which sadly cut in half my earnings but it’s so I can still make something and then people start to complain about this even though it doesn’t bother them in anyway

WHAT DO YOU PEOPLE WANT

so guys, I am going to ask you about something I am totally new on it.

what do you think about crypto currency mining? cam I do it using just my PC, if I can what is the estimate benefits?
do you advice me to proceed with this thing.

How much of fairness can human factor add to a government compared to foolproof AI algorithm. Is it too early or too utopiaic to trust AI with governance compared to agenda based corporate embracing environment destructing corrupt to the core politicians. Is AI more evil than today's politicians. Is there a project already similar to crypto currency on governance. On seeing all butt heads in power and in age where whistle blowers are caged I feel helpless tothink software cannot change the most primal thing - politics. Switching on TV and watching news had never been this disgusting. Flushing these thoughts , came back to my desk to learn something better and be at peace with programming.

I've been wondering for a while about something...why do so many devs complain sooo much when they have to to stuff not related to their main area of expertise.
I like learning and trying everything if I have the opportunity...backend, fronted, database, dev-ops, crypto, networking, virtualization...I stuck my nose in everything...but I see a lot of people moaning and despairing when they are thrown out of their comfort zone.
Like why...it's interesting... it's not always sunshine and rainbows but knowing something new in IT is never gonna hurt you...who knows maybe someday it's gonna help you get out a tight spot or land that awesome job you wanted.
Ok I'm done 😁

How would you guys feel if your favorite app gave you 3 monetization options.

Crypto Mining at max 70% load
Giving you 100% privacy.

Ads, rip privacy, rip cpu.

Paid content /micro transactions
Rip wallet , some privacy concerns, happy cpu.

Thoughts?

Does anyone else here think the regulating and centralising of crypto currencies and tokens worrying?
It is slowly being bent to the will of the higher ups just like traditional fiat and they’re burying its fundamental altruistic design concept without providing and means for it to be assimilated into benefiting the daily lives of the masses an especially the unbanked.

It has to be Keybase.

It is exactly what I need - A secure yet practical cloud storage, where only you own the crypto key, with the added bonus of maintaining a blockchain-based identity online, with proof system and all.
Also has a secure PKI-Based E2E chat when I want to talk to someone about something I don't want the general government to necessarily know.

Definitely recommend the service! Even with the odd decision to include an option of a Lumen crypto wallet or whatever, you can just ignore that feature if you're not into it and it doesn't slow you down.

I just went to cryptopia to check stats. They went bankrupt or what shit.
Anybody knows good crypto exchange site ?

Can't focus on work because Ethereum and litecoin are on the rise. Dreaming of driving lambos on the moon 😅

While Indian govt. talks about digitizing the country and is pushing ahead with it, their Employee's Provident Fund Org (EPFO) infra is absolutely shit and it's killing small time business that want to help their employees.

You need to add Digital Certs to do just about anything (great security wise) BUT,
The digital sign interface is written in Java Flash, that was dropped by all modern browsers 4 years ago.
The only stable working latest browser for it is Firefox 52 released 3 years ago.

The USB tokens used/supported are all Chinese that don't respect OSS drivers and fork built their own (read Watchdata) with no/shitty and cumbersome linux support (couldn't get it working after 2 nights of trying different versions of drivers).
You still have to run Windows to sign the docs or to interact with EPFO using legacy browsers from 2016

Non Tech problems: EPFO charges 500 Rs/month minimum admin charges, and I pay 1200 Rs PF for my driver. That kind of commission is plain stupid and will make small employers run away from paying PF for their employees.

Any interaction with EPFO is like having to eat thorns. painful, unnecessary bullshit. How useless can someone be building such a system released in 2019?
I just hope they fix it. A simple google search shows there is Web Crypto API for modern browsers. Someone wake these people up. SMH

Launch braiven.io, been working on it for last few months.. it's honestly everything I have ever learn in my 5 years of coding...I'm ashamed that I don't have a start-up yet and I can't get a decent salaried job since I don't qualify for most of them... But I can get a site up and I'm fullstack . So by week 200 braiven.io should be running like magic

Where do you buy your crypto currencies?

Why isn't Monero popular than Bitcoin, its practically the BEST crypto currency ever build, Satoshi Nakamoto did a great job, but come on!
Monero is factually EPIC!

Today I discovered trial and error driven development for myself:

Me, reading spec..
Spec: „Do something with an CSR“ (not the exact wording :D)

So instead of just googling C# + CSR and copying the code examples,
I went like:
What means CSR -> Certificate (Something Something)
-> could be this namespace (Something with „Crypto...“ in its name)
-> could be this class (Something with „Certificate“ in its name)
-> take the easiest overload (string is always nice)
-> try filling in the parameters from the spec
-> start debugger and inspect properties
-> repeat if necessary

I don’t know if this is the correct pattern to proceed my project with...
But hey, today it worked and now I also know, what „distinguished“ means

Noob question

Is it better to implement a cryptpgraphic algo in a function or in a class? Also how?

More info:
I have a cryptography class and I really enjoy implementing the different techniques that we study in class. At first I was just implementing the techniques in a simple function with 3 parameters; key, message and a bool for encryption or decryption. But as they are getting more complex, it is becoming harder to continue implementing them in a single function block. So I thought of using a class but ran into the problem of how do I even do that? Do I make different methods for key generation, encrypting and decrypting?

P.S. It's really just for learning how the crypto technique works and not for anything serious.

It may have to disappoint you, but ...
there is no cryptography in cryptocurrencies.

Crypto. I've seen some horrible RC4 thrown around and heard of 3DES also being used, but luckily didn't lay my eyes upon it.
Now to my current crypto adventure.
Rule no.1: Never roll your own crypto.
They said.
So let's encrypt a file for upload. OK, there doesn't seem to be a clear standard, but ya'know combine asymmetric cipher to crypt the key with a symmetric. Should be easy. Take RSA and whatnot from some libraries. But let's obfuscate it a bit so nobody can reuse it. - Until today I thought the crypto was alright, but then there was something off. On two layers there were added hashes, timestamps or length fields, which enlarges the data to encrypt. Now it doesn't add up any more: Through padding and hash verification RSA from OpenSSL throws an error, because the data is too long (about 240 bytes possible, but 264 pumped in). Probably the lib used just didn't notify, silently truncating stuff or resorting to other means. Still investigation needed. - but apart from that: why the fuck add own hash verification, with weak non-cryptographic hashes(!) if the chosen RSA variant already has that with SHA-256. Why this sick generation of key material with some md5 artistic stunts - is there no cryptographically safe random source on Windows? Why directly pump some structs (with no padding and magic numbers) into the file? Just so it's a bit more fucked up?
Thanks, that worked.

It's a great time to buy crypto and a shit time to own it.

Ticket: implement compression algorithm to crypto object x

Details: object to big, we must devise a way to compress it. A deflate algorithm should be added here, yada yada yada we did not have the time Yara yada...

Go see crypto provider's documentation... It has compression options... -_-

You lazy fucking stack overflow copy question dimwits!!! Jesus fucking Christ! This reached production like this shit, I've got clients complaining of the size of the payload because you are a bunch of lazy fucks who can't even read simple documentation!!!

I want to kill someone for wasting my time and patience... Don't call me for this kind of crap... I have better things to do!

I mean, the time it took you to write the ticket should suffice...

Quantum computing will break BTC private keys soon?

Maybe 2022?

Anyone here from Europe????? :D
JK
I just need a good bank here, with benefits, shoot me some best ones, also shoot me reference shits so you and I will have money :)!

If you want me to have some sort of crypto thing only, don't worry to shoot that on me too. I work for crypto company.

Do you guys think that it would be possible to build a cryptocurrency that could replace traditional banking and money at all?

A non anonymous cryptocurrency, that could guarantee enough privacy to not be used for surveillance but at the same time could be used by common people.

I had this thought recently but at the time of writing ( :P ) I haven't enough knowledge and time to go deeper than this (meaning "nothing").

I need some advice guys. I want to start investing in crypto currency. My question is where can I buy/sell, and which is the best website to keep an eye on prices? Do you use any kind of app for it?

Anyone in crypto mining?
Have a small question: why the fuck I am payed half of what I was expecting?!
I know the estimation is not accurate, but half of that or less?!?
(Estimation from the H/s)

Today I made my first crypto transaction! Donated $100 to Z-library which is around 0.41 ETH.

# This isn't THAT bad, but since I never had any collab before this one, this is the worst so far

I'm in a web development school where we need to do a yearly project. At the beginning, we started with the idea of doing an online wallet that would handle crypto-currencied (#blockchains), and other currencies too.
On the paper that sounds good, but the dude decided to create a NodeJS server api, and let's be honest, this was a gas factory. I couldn't help him because he was too fast in his ideas, and the third member was a bit more useful because he was the one creating the mobile app, so all he needed was an url that the dude couln't manage to create.

After a few weeks he started over the project, then over again a few weeks later, before coming to us and saying it was too difficult. We said "yeah, I mean you're own your own since the beginning, no wonders!" "Uh do you guys care if we change the whole project to do something else? Like a CV library"

Went a moment where he tried to over sell some incredible (read "overly common") features that already existed 10 years ago on some famous websites (ie. Monster), and he then eventually told me that this idea came from his new job, and that they needed this library. So we would have to work for his company for free. Nice.
The third guy and me came with a new idea (image recognition with IA and stuff), and we saw the dude maybe 5 times the whole week while we're supposed to work together

Name your favorite lesser known ico's, and why you think they have potential

Guys check out IOTA, get a light node wallet and buy some as long as it is still low. It is rising at a rising rate since some hours now.

IOTA is the solution to bitcoins speed and scalability problems. IOTA does not use the blockchain but instead a network called the tangle, which enables decentralized peer-to-peer transactions. There are no miners, no fees and the transaction validation speed depends on how many people are using the currency. One transaction requires your device to validate 2 other transactions through proof of work and therefore the system can never be overloaded by too many transaction requests.

Be warned though, the IOTA foundation is only currently building up the infrastructure, and people are just starting to trade since a few weeks so trasactions still may take a few hours.

Q.
Is it really right time to invest in Ethereum?

Do you have btc? If yes, how'd you get it? Do you feel its Ponzi?

Fuck you Linux! I thought user password validation would be a piece of cake, like bash one liner. How wrong could I be!

Yeah, it's already ugly to grep hash and salt from /etc/shadow, but I could accept that. But then give me a friggin' tool to generate the hash. And of course the distro I chose has the wrong makepswd, OpenSSL is too old to have the new SHA-512 built in, as it should be a minimal installation I don't want to use perl or python...
And the stupid crypto function that would do me the job is even included in glibc. So it's only one line of C-code to give me all I want, but there is no package that would provide me this dull binary? Instead I will have to compile it myself and then again remove the compiler to keep image small?

Developing a crypto currency infrastructure, a wallet and addressbook

I programmed a "crypographic" tool in python as my first application. It calculated the checksum of the entered password and preformed this cesa-shift-crappy-crypto thing. It was named crypto_mario and as I wasn't able to implement the decryption in the same application, I wrote a second one for that task, called crypto_wario

Well, how i can start...

I wanna disguise arcfour as a game (board or virtual), give it for free to kids, and someday tell them the goverment has banned the game because it's basically undistingable from arcfour, and then i'll try to explain for them the crypto controversy, and i know i did my work well if at least one of them decides to write a letter to the goverment.

I mean, i clearly know this is so frigged up, but i wanna know if it could actually work.

Not really the place for this, I know. But I am a crypto coin guy. And I work with numerous coins. I was curious if anyone new of an app the could monitor all of your cryto-coin addresses and give you something of a portfolio value. I am capable of doing so manually but the prices flux a decent amount so it changes from day to day.

In android 7.1, I've seen a lot of conflicting reports about crypto security.

If I do something like the following in the default android 7.1 browser...

var array = new Uint32Array(n);
window.crypto.getRandomValues(array);

How secure would the resulting numbers be overall? I'm asking because I've seen a lot of articles talking about it, but they never specifically mention the default 7.1 android *browser* and what or how it obtains secure random numbers. They only ever talk about the api, sdk, and developers working in java.
