A few weeks ago a client called me. His application contains a lot of data, including email addresses (local part and domain stored separately in SQL database). The application can filter data based on the domain part of the addresses. He ask me why sub.example.com is not included when he asked the application for example.com. I said: No problem, I can add this feature to the application, but the process will take a longer.

Client: No problem, please add this ASAP.

So, the next day I changed some of the SQL queries to lookup using the LIKE operator.

After a week the client called again: The process is really slow, how can this be?

Me: Well, you asked me to filter the subdomains as well. Before, the application could easily find all the domains (SQL index), but now it has to compare all the domains to check if it ends with the domain you are looking for.

Client: Okay, but why is it a lot slower than before?

Me: Do you have a dictionary in your office?

<Client search for a dictionary, came back with one>

Me: give me the definition of the word "time"

<Client gives definition of time>

Me: Give me the definition of all words ending with "time"

Client: But, ...

Never heard from him again on this issues :-P

Who actually started the reign of mixed character passwords? because seriously it sucks to have an unnecessarily complex password! Like websites and apps requesting passwords to contain Upper/Lower case letter, numeric characters and symbols without considering the average user with low memory threshold (i.e; Me).

Let's push the complaint aside and return back to the actual reason a complex password is required.

Like we already know; Passwords are made complex so it can't be easily guessed by password crackers used by hackers and the primary reason behind adding symbols and numbers in a password is simply to create a stretch for possible outcome of guesses.

Now let's take a look into the logic behind a password cracker.

To hack a password,
1) The Password Cracker will usually lookup a dictionary of passwords (This point is very necessary for any possible outcome).
2) Attempts to login multiple times with list of passwords found (In most cases successful entries are found for passwords less than 8 chars).
3) If none was successful after the end of the dictionary, the cracker formulates each password on the dictionary to match popular standards of most website (i.e; First letter uppercase, a number at the end followed by a symbol. Thanks to those websites!)
4) If any password was successful, the cracker adds them to a new dictionary called a "pattern builder list" (This gives the cracker an upper edge on that specific platform because most websites forces a specific password pattern anyway)

In comparison:
>> Mygirlfriend98##
would be cracked faster compared to
>> iloveburberryihatepeanuts

Why?
Because the former is short and follows a popular pattern.

In reality, password crackers don't specifically care about Upper-Lowercase-Number-Symbol bullshit! They care more about the length of the password, the pattern of the password and formerly used entries (either from keyloggers or from previously hacked passwords).

So the need for requesting a humanly complex password is totally unnecessary because it's a bot that is being dealt with not another human.

My devrant password is a short story of *how I met first girlfriend* Goodluck to a password cracker!
