        }

        public static string Encrypt(string cleanString)

        {

            Byte[] clearBytes = new UnicodeEncoding().GetBytes(cleanString);

            Byte[] hashedBytes = ((HashAlgorithm)CryptoConfig.CreateFromName("MD5")).ComputeHash(clearBytes);

            return BitConverter.ToString(hashedBytes);

        }
