AIM 5.0 Password Decryption

I need code written to decrypt AIM 5.0+ passwords. Here is a sample password: Encrypted: pfwd4CyKEtk1Mjp9tAnOHaX8HeAsihLZNTI6fbQJzh0= Decrypted: aim123 The password is stored in the regkey HKEY_CURRENT_USER\Software\America Online\AOL Instant Messenger(TM)\CurrentVersion\Users\USERNAME\Login\Password1 Whoever can provide me with the decryption algorithm will receive a HEFTY reward (especially if it is very soon). ## Deliverables All I need is the decryption algorithm source code, preferably in Delphi but if you can write it in another language that's fine. ## Platform I'm only looking for the algorithm - it can really execute on any system.
