Net2005中的MD5加密

其实在ASP.Net编程中,不用调用md5.asp来加密数据。在DotNet中有自带的类:System.Web.Security.HashPasswordForStoringInConfigFile()

  public string md5(string str,int code)
  {
   if(code==16) //16位MD5加密(取32位加密的9~25字符)
   {
    return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str,"MD5").ToLower().Substring(8,16) ;
   }
 
   if(code==32) //32位加密
   {
    return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str,"MD5").ToLower();
   }
   
   return "00000000000000000000000000000000";
  }
