I got it because just before the loggedin/wrongpass message I saw a string in the stack-window which turned out to be the correct pass. I don't get the encryption/decryption however. The program keeps encrypting/decrypting the functions, why?

Anti debug.
The algorithm itself is quite simple:
004013B0 -> strlen(name)
004013C5 -> password <- name ^ len

Ya, didn't spend a lot of time on that part ^_^. Took a while to make storage for the strings. The crackme part kinda ruined it because i had to compare them.

Well, at least it's suitable for someone who's just started learning ( I hope ).
