Don't do it that way.
what you want to do is push the password through a HMAC and store the results. Then when someone wants to login, get their password, push it through the same HMAC and compare the results.

A HMAC with SHA1 will do the job.
There are RFCs defining the standard way, and the java.crypto classes have the SHA code.
 
I agree. Here's the link: http://aspose.com/file-tools
