MD5 Encryption Function and Usage Example Implemented by C

In this paper, the encryption function and usage of MD5 realized by C # are described with examples. Share it for your reference, as follows:

1. Create the MD5Str. cs cryptographic processing class

public class MD5Str
{
  /// <summary>
  ///  String MD5 Encryption 
  /// </summary>
  /// <param name="Text"> String to encrypt </param>
  /// <returns> Ciphertext </returns>
  public static string MD5(string Text)
  {
    byte[] buffer = System.Text.Encoding.Default.GetBytes(Text);
    try
    {
      System.Security.Cryptography.MD5CryptoServiceProvider check;
      check = new System.Security.Cryptography.MD5CryptoServiceProvider();
      byte[] somme = check.ComputeHash(buffer);
      string ret = "";
      foreach (byte a in somme)
      {
        if (a < 16)
          ret += "0" + a.ToString("X");
        else
          ret += a.ToString("X");
      }
      return ret.ToLower();
    }
    catch
    {
      throw;
    }
  }
}

2. Run the test

static void Main(string[] args)
{
  string data = "123456789"; // Data to encrypt 
  string encodeStr = "";  // Encrypted text 
  encodeStr = MD5Str.MD5(data);
  Console.WriteLine(" Original text: {0}", data);
  Console.WriteLine(" Encrypted text: {0}", encodeStr);
  Console.Read();
}
