Help with programming for MySQL encrypted passwords?

[Matthew Good]

I thought I would rewrite my question...

I am trying to create a program that accepts a username and password for logging onto a mysql database. the usersnames and passwords where created in mysql administrator and navicat. I know that mysql encrypts the passwords it creates. these are the passwords i need to use. I figure that the connector/j driver passes a clear text password with no encryption.

So how do I get the password entered by the user to match up with the encrypted (or hashed) password stored (the one created by mysql administrator and navicat) on the mysql server?
