A very simplified C # message digest algorithm __ algorithm

  A message digest algorithm, such as a digest algorithm for passwords, is often used in programs. But in. NET is slightly more complicated, sometimes we want to do it in a simpler way, and the following code simplifies this process: using  System; Using  System.Collections.Generic; Using  System.Text; Using  System.Security.Cryptography; Namespace  oohacker.example ... {  public class mymessagedigest    {    //=========================================================================      //  returns a 40-bit SHA-1 encryption string    //============================================== ===========================      public static string hexsha (string  text)      {      return makedigesttemplate (SHA1). Create (),  text);     }     //=========================================================== ==============     //  Returns an MD5 encrypted string with a length of 32 bits     //=========================================================================     public static string &NBSP;HEXMD5 (String text)      {      return makedigesttemplate (MD5). Create (),  text);     }     //=========================================================== ==============     //  Encryption Templates    //======================================== =================================     private static string  Makedigesttemplate (Hashalgorithm algo, string text)      {      byte[] data = algo.computehash (ASCIIEncoding.ASCII.GetBytes (text));       stringbuilder codes = new stringbuilder ();       for  (Int i = 0; i < data. LengTh; ++i)        {        codes. Append (Data[i]. ToString ("X2")); &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP}       return codes. ToString ();     }  &nbsp}}

The use method is simple, as follows: string strmd5 = Mymessagedigest.hexmd5 ("Oohacker"); String Strsha = Mymessagedigest.hexsha ("Oohacker"); Console.WriteLine ("Hex MD5 encryption: {0}", STRMD5); Console.WriteLine ("Hex SHA-1 encryption: {0}", Strsha);

The output results are as follows:

Hex MD5 encryption:eccca05fb779dcece81656890773b7bf Hex SHA-1 encryption:67576ffe5410fb70651ef8fd550ecdb7a9901603
