how can a bruteforce occur on a pbkdf2?

Question

am sorry for this question, but i was asking: when using MD5, we get a hash, so to get the password we hash all the words untill we find the same hash.

but in a key derivation algorithme such pbkdf2 or bcrypt or scrypt, what a hacker need to seek? or he will make the same algorithme to all words to get the same key derivation?

am sorry for this dumb question.

It’s the same general idea - try all the hashes - but several thousand (or million, or even billion) times slower.

so he uses the same algorithme? – Abdelouahab Pp Dec 25 '12 at 22:57

@AbdelouahabPp: No, they’re all different hashing algorithms. – Ry- Dec 25 '12 at 22:58
but the brutefore is the same? – Abdelouahab Pp Dec 25 '12 at 22:59
ah ok, thank you, because i thought that even the bruteforce must make an intermediate operation, i was dumb ^_^ – Abdelouahab Pp Dec 25 '12 at 23:02
