Message: [QUOTE="Lew, post: 5050394"] First of all, hashing a unique integer is silly. It's already unique! If you have a reliably unique, stable integer ID, you don't need to hash it! Just use the value. Got that? Good, because an internal database ID is not reliable. It's *internal*! It's not meant to be used externally! Got that? Good, because the database record has (or you're not doing it right) an external unique key, one based on visible attributes. You could hash that key. Or you could perhaps use [URL]http://docs.oracle.com/javase/7/docs/api/java/rmi/server/UID.html[/URL] You'll want to store that UID with the registration record. First and foremost google around for hash codes and how to use them. Your lack of understanding will screw you otherwise. [/QUOTE]
