MD5-Something Screwy

Yah... this is somewhat odd. The only thing I can think of is that (I'm using Vbulletin) that Vbulletin does something else to the password after encrypting it. I'm trying to link it to my Ragnarok server but the server is looking for completely different hash than what is in the database. I've been told is mathematically impossible to have the same txt string come out in different hash lol
I can't seem to figure out why either... I looked at the control panels for ragnarok and they're just as I expected. There's a simple md5 tag and then the password post to sql, thus why I think it's Vbulletin.

If anyone knows what's going on here that would be great lol. I'm not 100% sure how md5 works lol, obviously ^_^ There's some key element somewhere that I'm missing

Aint really played around with vbullitin...but cant you edit the signup form and have it sign up to 2 dbs?

or is it all encrypted hehe

Hmm, I found the problem I think lol
Vb has a md5 file that gives it it's own encryption. "vbulletin_md5.js"
I've no idea how to change it to be the same as the server's now lol...

I really wanted them to be the same login back right now it looks like it may not be happening.

**Edit**
Okay either that or insert another field with just regular md5 encryption or without it. But then I need all the features to work for that too like password changing and what not lol

**Edit2**
Okay sorry... it doesn't "Encrypt it" it just puts it in a hash form which I have just learned the difference of lol.
Apparently it puts a "Salt" at the end of the password randomly and uses that for extra protection. So all I need to do is remove the salt from it and I should be good ^_^

usually is not a very good idea to just hash a password, so I'm guessing vbulletin does it the good way: take the password string, concatenate another string to it (like username or even a constant string), _then_ hash it.

Yah I know what it does lol
And no it's not good... lol
I've pretty much given up on the idea at this point of combining the two :(
Now I'm just making a separate Cp and linking those two which is much easier lol

Plus I doubt anyone would go through and tell me what files to change and where.
