How to decode Yahoo Messenger saved password?

[Masroor Ehsan <ophelia () proshikanet-ctg com>]

Hi list!
Does anyone know how Yahoo Messenger encrypts it's password? I know it's 
stored in the "HKCU/Software/Yahoo/Pager/EOptions String" registry key. Can 
anyone share some thought/code on how to decrypt the pass?

The password decoder YPass.exe uses the yahoo dll (ycrwin32.dll). Anybody 
knows which functions this program calls?

Regards.
