RSA的加密和解密。运行在VC++6.0下。(RSA encryption and decryption)

本源代码，综合了DES，RSA,MD5等几种加密的方法于同一工程中，可以让读者对各种加密方法的实现通过代码实现过程的比较，更好的理解几种软件加密方法(Source code, a combination of DES, RSA, MD5 encryption method, such as several in the same project, will allow readers to a variety of encryption methods to achieve the realization of the process through code comparison, a better understanding of several software encryption methods)

Motivation - A simple DES core  - Fast and Small Version  - Open Source Compatibility I believe that the core complies to NIST-800-17. However, there has been no formal third party verification. The official NIST specification can be downloaded here: 800-17.pdf. For the Triple DES, the NIST reference is located here: 

VC编写的简单DES加密程序，密钥由用户手动输入，可加密字符串(VC prepared by the simple DES encryption program, the key to manually input by the user)
