I wanna extract algorithms for key generation from known programs, so I think I should learn assembly before, am I right? Anyways thank you for the replies.
EDIT: Now I am trying to crack LaFarge #2 crackme, but it seems still too early...
Has anyone got a good Assembly and RE guide? At the moment I can't find anything good... I have already finished the ones that white-knight suggested me, but I think they were too easy even though they were really well explained.
[Sorry for any grammar error but I am not english]
