Encrypted email browser.

Desktop application for sending and receiving encrypted email. should be able to create own asymmetrical rsa algorithm without using ms libraries. high level of math skill necessary for this. the app should have a built in browser window into which user can open his favorite email , such as gmail or whatever. Then a input area where he can actually compose the mail, and on clicking a button the entire contents of the input area are encrypted with unbreakable encryption and the resultant gibberish is pasted into the message area of gmail and sent. same thing for receiving email, gibberish is pasted into the input area and decrypted. So basically a powerful encryption decryption system that can be used with any online email service. Ideally you should combine multiple encryption methods to create something unbreakable.
