Salt

[Audentio]

Can anyone explain the salts in the database table vb_user? I want to make a login and register form on my site and I want it to work with vB meaning that people can log into their accounts on the forums from the main site or register from the main site, but I don't want to touch anything into I know more about salts. Can someone please explain them to me?

Its a random three character string that is used to encode the password with MD5 to prevent the same password being stored with the same hash.

The password is stored as MD5(MD5($password) . $salt)

To integrate the two systems, you should look login.php and the corresponding articles over at www.vbulletin.org.

Yeah, I recall older versions of vBulletin in which I could see my test accounts on the forum, which had the same passwords, would have the same hash password in the database. Now two people with the same password won't even have the same hash anymore, because of the salt.
