md5加密函数 

 1 /// <summary>
 2 /// 使用MD5算法加密（不可逆，无法解密）
 3 /// 把此方法加入CS页面然后直接调用就行了
 4 /// </summary>
 5 /// <param name="password">明文</param>
 6 /// <returns>密文</returns>
 7 public static string EncryptionMD51(string password)
 8 {
 9 System.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create();
10 byte[] bytes = new byte[16];
11 System.Text.ASCIIEncoding asc = new System.Text.ASCIIEncoding();
12 bytes = md5.ComputeHash(asc.GetBytes(password));
13 return Convert.ToBase64String(bytes);
14 }
15 
16  
17 
18 但是我们通常使用utf8的编码方式

20 public static string EncryptionMD51(string password)
21 {
22 System.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create();
23 byte[] bytes = new byte[16];
24 System.Text.UTF8Encoding asc = new System.Text.UTF8Encoding();
25 bytes = md5.ComputeHash(asc.GetBytes(password));
26 return Convert.ToBase64String(bytes);
27 }
