There is a fun book about cryptography, it is not all about computes but it is called codes. It is a great read.

about theory: I think the best way to learn theory is to also learn history: start at simple transposition and monoalphabetic substitution ciphers, then go all the way to modern encryption. writing encryption/decryption software is not hard when you know both theory and programming. cracking is difficult as you need to know a lot about cryptanalysis and a lot of math. also, using encryption everyday doesn't require more than a basic theory and good software (TrueCrypt and PGP should be enough)

Exactly, thats what the book I suggest does.

I tried cain n abel to crack md5 hashes but never got a single.. how it can work? i used brute force technique.
RE: Learning Encryption - unknownAttacker - 10-21-2012
bruteforce will work... sooner or later, as it tries every possible combination. to speed up the process you can download (or build, if you have time) rainbow tables

Never used cain n abel as I'm not a windows user but brute forcing a strong hash could take a couple of lifetimes to be honest if the password is 16 chars forget it lol there are some distrobuted cracking softwares out there, which each user uses a portion of his/her hardware to crack hashes on a server.
RE: Learning Encryption - unknownAttacker - 10-22-2012
md5 is not that strong, but distributed is a good idea anyway

OK, what is the book? I mean the name?
