二阶希尔加密

加密解决算法，有兴趣的可以瞧瞧，不太清楚如何使用-encrpt

LZW算法基于转换串表(字典)T,将输入字符串映射成定长(通常为12位)的码字-LZW algorithm is based on converting Series (dictionary) T, the input string mapping into fixed-length (usually 12) the code word

详细介绍了C函数。

一款asp.net 高效能的c#加密解密程序(A high-performance encryption and decryption of c#)

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )
