VC++编写实现的文件加密程序，可实现RAR、exe/jpg等格式文件的加密，在使用时，打开程序，只需选择被加密的文件，然后输入加密密钥，设置文件保存的路径，点击“开始加密”按钮，即可快速实现文件的DES加密处理。源代码基于VC++编写，在VC6.0环境可直接编译。-VC++ prepared to achieve file encryption program, enabling RAR, exe/jpg format files such as encryption, when in use, open the program, simply select the encrypted file, and then enter the encryption key, set the path to save the file, click the "　Start Encrypt " button, you can quickly achieve a DES encrypted file. Source code is based VC++ written in VC6.0 environment can be directly translated.
