C # implementation MD5 encryption

1. First create a MD5 hash algorithm.

((HashAlgorithm) System.Security.Cryptogrophy.CryptoConfig.CreateFromName ("MD5")). ComputeHash (System.Text.UTF8.GetBytes (input))

2. Calculate the hash value

Use method: ComputeHash (byte[] value);

3. Convert to String.

1protected virtual string HashMD5(string input)
2    {
3      byte[] result = ((HashAlgorithm)System.Security.Cryptography.CryptoConfig.CreateFromName("MD5")).ComputeHash(System.Text.Encoding.UTF8.GetBytes(input));
4      StringBuilder output = new StringBuilder(16);
5
6      for (int i = 0; i < result.Length; i++)
7      {
8        // convert from hexa-decimal to character
9        output.Append((result[i]).ToString( "x2", System.Globalization.CultureInfo.InvariantCulture));
10      }
11      return output.ToString();
12    }
