Detailed introduction to C # Implementation of MD5 encryption and usage examples

This article mainly introduces the MD5 encryption function and usage of C # implementation, and analyzes the definition and use method of C # MD5 encryption class with the example form, the friend who needs can refer to the following

This paper describes the MD5 encryption function and usage of C # implementation. Share to everyone for your reference, as follows:

1. Create MD5Str.cs Encryption Processing class

public class md5str{//<summary>//  string MD5 encryption//</summary>//  <param name= "Text" > String to encrypt </param>  //<returns> redaction </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 <)          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 be encrypted string encodestr = "";  Encrypted text ENCODESTR = MD5STR.MD5 (data);  Console.WriteLine ("Original text: {0}", data);  Console.WriteLine ("Encrypted text: {0}", ENCODESTR); Console.read ();}
