Decrypting the hashed windows passwords in SAM

I realise passwords are hashed using LMHash and then encrypted using SYSKEY, is there an开发者_如何学Goy sort of implementation code (preferably in Java) for SYSKEY so that i can create rainbow tables?

The sites I could link to are fishy and I''m not sure if they are safe, but you can google syskey rainbow tables and you'll find some information you need.

However, you should probably shouldn't unless you need this information for ethical reasons.
