Hash: SHA1



I know that and you probably misread the question or my explanation was
not clear enough.

My question was: is hashing two or three times (without a salt) a secure
method or is it as secure as hashing only one time without salt?


Oh sorry, I really misunderstood your question.

As far as i understood, it can significally improve the secure of the
"clear text" passwords but, with a reaaaaaaally big hash db, you can
crack it.

I do agree with you when you say that it will give the same hash for
same passwords, even if i hash it infinite times. So i guess that I'll
have to study the security/performance effects of such measure. Maybe
one day I'll present it to the world.

Thanks all for the answers. I'm really grateful.
