For encryption program code, is a very good code, and may generate a serial number for your software,

这个源码是实现VIGENERE算法的加密解密程序,界面操作简单,一看就明白-This source code is to achieve VIGENERE algorithm encryption decryption process, simple operation interface, a see will understand

AES 加密算法的演示代码 解压后用VC打开即可,不错的(AES encryption algorithm demo code After decompression with VC open can. Good)
