I am (have been for two months) thinking of starting an email service that is compatible with the current email system, but adds features.<p>-If server is stolen by authorities they got nothing;<p>-RSA/public key encryption on every email. Every user has a public key and incoming mail is encrypted on the server right away. Public key is available for every email upon request, then other party encrypts and not the server. (this is so that other providers can implement this protocol)<p>-Downloadable apps to prevent 'man in the middle' attacks.<p>-Private key is generated via a standard procedure, client side, on every login. User password (such as 'correct horse battery staple') will be the 'seed' for the procedure to generate private keys.<p>I need help for this project. Please respond if interested or for any suggestions.
