A password will make you a "w1nnar". Doesn't matter if Uligor encrypted "zomgwtfbbq" with another algorithm and set that as the data. You are not trying to find "zomgwtfbbq". You are trying to find the password, the string that makes you a "w1nnar".

Too easy my friend, Uligor. ;P

password db 'iloveuli',0

Bahblah, I could make it impossible too. ;p
By just salting and hashing my password and then compare it to a hash. Smile

Good job nonetheless. ;p

Reversing. Then backtracking each step using the code itself and OllyDbg's nice "Set this point as EIP"' or w/e

Exactly how you said, dezuzi. He took each dword and reversed it (pass is stored in static)
