Running a Brute Force Attack Simulation...

Hi everyone!

I was bored so i was running a brute force attack on a simple encryption scheme i came up with. I'm using a known plaintext and known (complementary) ciphertext. So the computer's job it to guess the key until it finds the right one.

The encrypt() function i wrote works both as the encryptor and decryptor, it acts on two given strings (plaintext and the key) and returns a string (the enciphered one).

My question now is, how do i get the computer to start guessing? i.e. ->

1. "a"

2. "b"

3. "c"

...

27. "aa"

28. "ab"

...

53. "aaa"

54. "aab"

...

etc.

Thanks!
