Digital signatures for secure communication

The aim of the project is to make an application which helps people to communicate on a locally developed insecure communication protocols like, college libraries, small scale industries etc. While providing security for such communication protocols. This is achieved by using one of the most popular RSA encryption technique with key size selection for users. A database is also made for storing the users as well as the passwords of said users. The message is send from one computer to the other using socket programming and sever client model. This application is made on java platform for easy portability on any system. This developed utility can easily configure and install on any developed communication protocol for privacy as well as security.
