Encrytion problem

[Compumaniac12]

i know the basics of encryption, Crypt(); salt whatever.

i need to figure out what encrytion phpbb2 uses, not to decrypt it, but to match it.
In simpler terms i need to make a login for my website thats interlinked with the phpbb2 forum database, so when someone registers its for both my site and the forums. i havent looked for that long so if noone has prior experiance on this i understand, but if theres a code (even extensive) it would be great to get my hand on.

Thanks
