How do I create a password hash in java for 4.1.x

[Zissis Trabaris]

I am creating a java based multiplayer game and would like to allow my users to log into the java game using their IPS username and password. I have the password hash and seed hash from the IPS database but since IPS 4.1.x no longer uses MD5 hashing I was wondering if anyone has some java code to combine the password string with the hash seed to create the password hash that is stored in the database?
