Hello guys, I need to code a basic application for my cryptography class using JCE.
The problem is that I am not that familiar with java and I am quite lost and don't know how to start.

Basically I need to create a password keeping tool such as keepass.

How can I use JCE classes to build an application that encrypts a file containing passwords please?

If someone could explain to me simply how I can do that and how I can start that project, it would be really nice.

I am not asking yoy to do it for me, just to help me and show me how I can start it ( for example which classes to have etc..)

Thanks a lot
