SMF 2.0 RC3 Account Authorization Algorithm

[SpartanLegends]

Now, I'm sorry for coming here so rapidly on a question that I could probably answer by even peeking at some of the code, but a search provided no insight, and I think this is a bit of a specific question.

What I am looking for is the algorithm used to authorize a login. I know the new version of SMF uses a nice and secure SHA1 with 4 digit salts, but I'm not sure of the algorithm.

As an example, vBulletin uses 'md5(md5($pass).$salt)', but what about SMF?

Apologies if this question is somehow misplaced, silly, or something like that, and thanks to any and all assistance.

to authorize a login or check the password

the salt isnt used for the username/password check
its sha1(strtolower($username).$pass) in the main db


as for authorizing a login it looks like
sha1($pass.$salt)

Although at the time I must have not made it clear, probably because I didn't think on that part of it, but I was looking for as many of the generic algorithms used. The only thing I needed to know was to confirm that the input password was the correct password, and you seem to have helped. Thanks.

The part I was looking for.

sha1($pass.$salt)

Ok, uhm, new problem. I'm not able to duplicate the hash properly, and it seems to reject the password with the proper hash and salt. Hrmf.
Nevermind, ok, I finally got it to work, now I can use it properly. Thanks!
