Java Development

Hi all,

My system enables users to save their work as a draft. I'd like to encrypt the data before I persist it. What APIs / tutorials should I be looking at?

I'm working with JDE 4.5.0, In particular, what I'm worried about are 

- Where do I save the keys?

- How processor intensive is crypto? Something like Triple DES / AES?

Thanks,

Teja.

Okay, seems I need a byte stream to encrypt. I need to persist an object, so any tips on getting a byte stream representation of an object that can be converted back?

What's your thread model? What are you trying to protect against?
