利用VC来实现一个简单的DES加密程序，他能完成DES算法的全部步骤，不过只能使用64位密码对64位明文进行加密-VC to achieve a simple DES encryption program, he can finish all the DES algorithm steps, but only use 64 to 64 passwords expressly encryption

md5的加密函数 iis下运行； 用法: 1：页面包含该文件 2：调用方法MD5(sMessage,stype) 例dim md_=md5("admin"，32) *注：最高32位。-md5 encryption function running under iis Usage: 1: page 2 of the document contains: call method MD5 (sMessage, stype) were dim md_ = md5 ( " admin" , 32)* Note: maximum 32.

最新的AES源代码，AES加密算法为我们提供了强大快捷的对称加密方法。-the latest source code AES, AES encryption algorithm to provide us with a powerful and efficient symmetric encryption method.

DES算法的C语言实现，大家可以参考一下。-DES algorithm to achieve the C language, we can reference.

写专属或加密程序。 程序应该采取作为输入由程序然后加密的文件名。 程序应该要求用户输入密钥，应该用于加密文件。 程序的输出应该进入一个文件以同一个文件名，但.ENC引伸。-Write an exclusive-OR encryption program. The program should take as input a filename that is then encrypted by the program. The program should ask the user to input an encryption key, which should be used to encrypt the file. The output of the program should go into a file with the same filename but a .ENC extension.
