通過C＃加密和通過SQL Server 2008 for ASP.NET應用程序解密

Question

在前端，我具有以下功能：

加密方法：

  public static string Encrypt(string strToEncrypt)
        {

            TripleDESCryptoServiceProvider objDESCrypto = new TripleDESCryptoServiceProvider();
            MD5CryptoServiceProvider objHashMD5 = new MD5CryptoServiceProvider();
            byte[] byteHash, byteBuff;
            byteHash = objHashMD5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(GetEncryptionKey));
            objHashMD5 = null;
            objDESCrypto.Key = byteHash;
            objDESCrypto.Mode = CipherMode.ECB; //CBC, CFB
            byteBuff = ASCIIEncoding.ASCII.GetBytes(strToEncrypt);
            return Convert.ToBase64String(objDESCrypto.CreateEncryptor().TransformFinalBlock(byteBuff, 0, byteBuff.Length));


        }

解密方法：

public static string Decrypt(string strEncrypted)
        {

            TripleDESCryptoServiceProvider objDESCrypto = new TripleDESCryptoServiceProvider();
            MD5CryptoServiceProvider objHashMD5 = new MD5CryptoServiceProvider();
            byte[] byteHash, byteBuff;
            byteHash = objHashMD5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(GetEncryptionKey));
            objHashMD5 = null;
            objDESCrypto.Key = byteHash;
            objDESCrypto.Mode = CipherMode.ECB; //CBC, CFB
            byteBuff = Convert.FromBase64String(strEncrypted);
            string strDecrypted = ASCIIEncoding.ASCII.GetString(objDESCrypto.CreateDecryptor().TransformFinalBlock(byteBuff, 0, byteBuff.Length));
            objDESCrypto = null;
            return strDecrypted;

        }

並且GetEncryptionKey函數是

   private static string GetEncryptionKey
    {
        get { return "#$&*(^($%"; }
    }

編輯：現在這是我的問題：因此，有人要求使用前端編寫的加密功能（在注冊或更改密碼時）對用戶的密碼進行加密，並通過存儲過程（在登錄期間）對加密的密碼（從前端）進行解密。 我該怎么辦？
