IPB password encryption algorithm.

[GTX]

Does anybody know what's IPB password encryption algorithm? I think it is SHA1, but I can't get it to work.

I tried:

- sha1(salt..password)

- sha1(hash..password)

- sha1(user..password)

And I tried md5 also and none of it did work.

Thanks in advance.

Edit: I'm using IP.Board 3.3.4

Edit 2: Solved.

should be md5(md5($salt) . md5($password))

edit: Also found one awesome tutorial
