Password Hashes and Databases

[omegaweapontmod]

Okay, I want to create a third party login program using Visual Basic. I know how to create the program, but what would the program check with to authenticate the password and username? I know it's a database but what specifically?

Passwords in vBulletin are hashed like so:

PHP Code:

md5(md5($plaintext) . $salt) 


The hash and salt is located in the user table.

I am not good with PHP, what does this mean?

--------------- Added [DATE]1242925151[/DATE] at [TIME]1242925151[/TIME] ---------------

How would I write this as a database? I need more info that just the code :P
