Hey guys.

I need to do encryption for my current program.
It's all new to me.
I've checked on the web and got some sort of idea, but can't find much, but I find there really is a lot to it. I was just wondering if there is a tutorial or a site or any thing where i can get the basics and get started. (from what I've seen I'll be using JCE. or maybe I'm wrong, once again, not sure)

Please help...
thanks in advance.

http://articles.techrepublic.com.com/5100-22-1046088.html looks like a decent tutorial.

The http://faq.javaranch.com/java/SecurityFaq links to ready-to-run code for doing DES and AES using JCE.

I busted about a year in my design trying to do get-going work on real protections. I recently purchased Java Cryptography Extensions by Jason Weiss and shipped 56-bit DES to Team Lead within a day of starting work on the book and told them to bust it .

It's been a week, they have not embarrassed me yet.
