A RSA algorithm simulation method using C language

In order to solve the problem that data leakage is existed in the Internet era, this paper uses RSA algorithm to encrypt data. First, the basic concepts of cryptography are proposed, and then the basic principles of the RSA algorithm are given. This paper uses C language to simulate RSA algorithm and C/S structure to realize ciphertext transmission. Experimental results show that the RSA algorithm can be used to encrypt data.
