Abstract :
This paper describes a complete set of practical solution to file encryption based on RSA algorithm. With analysis of the present situation of the application of RSA algorithm, we find the feasibility of using it for file encryption. On basis of the conventional RSA algorithm, we use C + + Class Library to develop RSA encryption algorithm Class Library, and realize Groupware encapsulation with 32-bit windows platform. With reference of this Groupware on Net platform, you can realize the window application of encryption operation on any files with RSA algorithm.
