===这个是DES方式加密解密字符串的
System.Security.Cryptography.MD5CryptoServiceProvider md5=new System.Security.Cryptography.MD5CryptoServiceProvider();
return Convert.ToBase64String(md5.ComputeHash(System.Text.Encoding.Unicode.GetBytes(yourstring)));
===这个是MD5的
实现代码也给你写好了，希望能对你有帮助

不算你用MD5加密了，难道密码用户名就是不明文了吗？
推荐使用DES加密，将整个字符串进行加密，使用时对字符串进行解密，如下：
DataBaseConnection ="zYm7yKtPbpA60pXHe2SJHFedFT1f9AO37dtGZGp5Zxq3paNswSNzDpWcGoxOC2vldeYipCRWihk6KoHWCrpXFmLRBuGCVRjwyUk/0Ku5XnA="
Application("shujuku") = 解密(DataBaseConnection);
解密后就可以使用了，希望对你有所启发！
