I have a problem... i'm building a system which runs besides vBulletin, and the user has to login there again... but i cant find how vBulletin generates the password in the database..

i tried md5($password), md5(md5($password))... but they didnt work..

anyone can help me?

thanks a lot

Here's an example from php.net:

As you can see, the md5(); function does indeed work as you tried, I'm just guessing you applied it wrong.

If you want, you can post the bit of code you're working on, so we can help you out.

(md5 explained at php.net)

thx for the help, but thats not exactly what i want..
i mean, the user must login in my system with the same user and same password that he logs in vB forum...
but for example, my password is "123456".. i use md5("123456") but the result doesnt match with the password in vBulletin "user" table.... i think vbulletin use a "combo of md5s" like md5(md5(md5("123456"))), but that doesnt work...

i wanna know exactly what vBulletin does with my password to generate the hash in the database

if you want to take a look at login.php and also register.php in your vbb files, you will find out how vb creates a unique salt and stores it in the user table corresponding to each user, and applies that salt along with a stored md5 hash to verify the user account login. maybe this will point you in the right direction..

oh... now i realize...

echo md5(md5($password) . $salt);

thanks a lot for the help sphinx
