MD5加密 登录用户名密码

   以前,不太清楚,加密是怎么弄的,觉得好奇,后来 我们老师给我们写了一个很简单的, 就是用 ^ 异或字符做的,我想估计很容易就被破解了吧,一直听说有个加密算法是MD5,

前不久才接触到这个,呵呵,拿出来分享一下

 

// using System.Security.Cryptography;
public class ACMMD5
        {
            private static MD5 md5 = new MD5CryptoServiceProvider();
            private static string attachedCode = "mulberry";
            /// <summary>
            /// 结合登录名用MD5来加密密码
            /// </summary>
            /// <param name="LoginName">登录名</param>
            /// <param name="Password">密码</param>
            /// <returns></returns>
            public static string EncryptPassword(string LoginName, string Password)
            {
                byte[] loginNameByteArray = md5.ComputeHash(Encoding.UTF8.GetBytes(LoginName.ToLower()));
                byte[] passwordByteArray = md5.ComputeHash(Encoding.UTF8.GetBytes(Password));
                byte[] attachedCodeByteArray = md5.ComputeHash(Encoding.UTF8.GetBytes(attachedCode));
                List<byte> finalByteList = new List<byte>();
                for (int i = 0; i < attachedCodeByteArray.Length; i++)
                {
                    finalByteList.Add(loginNameByteArray[i]);
                    finalByteList.Add(attachedCodeByteArray[i]);
                    finalByteList.Add(passwordByteArray[i]);
                }
                string result = Encoding.UTF8.GetString(md5.ComputeHash(finalByteList.ToArray()));
                return result.Replace("'", "''");
            }
        }
