使用rsa算法加密... [英] encryption using rsa algorithm...

问题描述

该代码用于使用rsa算法加密任何字符串，因为unicode的值变为零，所以该代码未运行，请检查我的错误..

this code is for enryption any string using rsa algorithm this code is not run because value of unicode become zero so check my mistake..

protected void Button1_Click(object sender, EventArgs e)
  {
      string ab;
      int unicode;
      ab = TextBox1.Text;

      foreach (char c in ab)
      {
           unicode = c;
          Console.WriteLine(unicode < 128 ? "ASCII:{0}" : "NON-ASCII:{0}", unicode);
          Response.Write(unicode);
      }

      Response.Write(unicode);
     Response.Write("Enter the value of p");
      double p=0,q=0,o=0;
      double d,c;
      string str = char.ConvertFromUtf32(unicode);
      Response.Write(str);
       p = (double)Convert.ToInt64(TextBox2.Text);
       q = (double)Convert.ToInt64(TextBox3.Text);


     /* if (!Int32.TryParse(TextBox2.Text, out p))
      {

      }
           if (!Int32.TryParse(TextBox3.Text, out q))
      {

      }*/

     double n = p * q;
     double q1 = (p - 1) * (q - 1);
          Response.Write(q1);

          o = (double)Convert.ToInt64(TextBox4.Text);
   /* if (!Int32.TryParse(TextBox4.Text, out o))
    {

    }*/
    d = (Math.Pow(0,-1)) % q1;
    c = (Math.Pow(this.unicode,n)) % n;

    Response.Write(c);
    unicode = (Math.Pow(c,d)) % n;
   Response.Write(this.unicode);
 //  Response.Write(unicode);
 string str = char.ConvertFromUtf32((int)unicode);
 // Response.Write(str);*/

       }

推荐答案

使用RSA加密的编程方式:

using encryption witg RSA programmaticaly:

System.Configuration.Configuration config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/");
            System.Configuration.ConfigurationSection appSetting = config.GetSection("connectionStrings");
            if (appSetting.SectionInformation.IsProtected)
            {
                appSetting.SectionInformation.UnprotectSection();
                Label1.Text = " ConnectionString  is decrypted";
            }
            else
            {
                appSetting.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");//default used encription is DPAPI but if you want use RSA encryption use this one provider RsaProtectedConfigurationProvider
                Label1.Text = " ConnectionString  is encrypted";
            }
            config.Save();
