One of my favourite, encryption puzzles is this:

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

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

@BambuSource haha, good try! But that's not it. :D

I DONT KNOW

This very much looks like (ssh) RSA.
Hmm.

@Haxk20 Hmm isn't base64 ussually y'know. 64 long.

@Haxk20 good work! :D

@Haxk20 Sure, try this one:

EB VA YIAEV DVC BRDZYRS CLWAAT JYSC Y LWDTJ VWDHXC, HYVERYTTS, AHTS AM BTYS.

Answer is in english.

The owls are not what they seem

The Base64 string is also not what it seems. If you understand the truth, you'll find it's not the Base64 string that rotates, but yourself.

@ethernetzero beautiful! :D

@ClySuva nice code, you got any more samples with that cypher? I'm testing a frequency analysis / unknown code decryption software.

Sadly I couldn't decrypt it yet.

15 18-15-6-5-4 4-16-9-3-17-16-4, 4-16-23-4 25-9-3'2-19 11-23-20-19 4-16-15-5 22-19-21-23-3-5-19 9-18 17-6-23-2-15-4-25 18-23-12-12-5. 15-4'5 23 2-19-6-25 10-15-21-19 5-19-6-15-19-5 23-10-20 25-9-3 5-16-9-3-12-20 21-16-19-21-13 15-4 9-3-4.

(This cipher was used in a popular animated series.)

@Haxk20 Close enough! "thinks" not "things".

It is a simple character substitution cypher. But, the point is, the phrase is taken from a book called "Gatsby", a book which does not contain a letter "E", the most popular letter in english alphabet.

This confuses the frequency analysis and makes people think it is some different cypher. :)

Good work!

@LinusCDE I FIRST THOUGHT, THAT YOU'VE MADE THIS BECAUSE OF GRAVITY FALLS. IT'S A VERY NICE SERIES AND YOU SHOULD CHECK IT OUT.

Nice!

@LinusCDE "I first thought that you've made this because of Gravity Falls. It's a very nice series and you should check it out!"

I have watched it and I totally agree. Awesome series!

I just realized I used uppercase letters for no good reason. I shouldn't have been playing Thimbleweed Park until 4 a.m. last night. :P

@ethernetzero @ClySuva 👍

@ethernetzero No problem. I also always used uppercase letters when decoding the messages in the series.

@ClySuva I thought u said Gatsby as in the great Gatsby book doesn't have e in it.

But it's some other book.

Yeah, not Great Gatsby, that one already has E in the title.

Now when I checked it, it's called Gadsby:
