C#中Rsa算法的源代码 [英] Source Code For Rsa Algorithm In C#

问题描述

任何人都可以给我c#中的rsa算法的源代码，该代码通过code加密和解密文件.意味着使用StreamWriter函数.该函数将通过code给出文件并创建两个文件，一个被加密，另一个被解密文件.

Pls can anyone give me a source code for rsa algoritm in c# which encrypt & decrypt a file through code.means using StreamWriter function.that function which will give the file through code & create two files one is encrypted & other is decrypted file.

推荐答案

RSA加密，但仅用于字符串:

RSA encryption but just for strings:

using System;
using System.Collections.Generic;
using System.Text;
using System.Security.Cryptography;
namespace RSA
{
    class Program
    {
        static void Main(string[] args)
        {

            RSACryptoServiceProvider myrsa = new RSACryptoServiceProvider();

            System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();//Encode String to Convert to Bytes

            string data = "RsA EnCryPTion is cool!!!";//whatever you want to encrypt
            
            Byte[] newdata = encoding.GetBytes(data);//convert to Bytes
                             
            Byte[] encrypted = myrsa.Encrypt(newdata, false);

            Console.WriteLine("Encrypted Data:  ");
            for (int i = 0; i < encrypted.Length; i++)
            {
                Console.Write("{0} ", encrypted[i]);
            }
            Console.WriteLine();
            Console.WriteLine();

            Byte[] decrypted = myrsa.Decrypt(encrypted, false);//decrypt 
            Console.WriteLine("Decrypted Data:  ");

            string dData = encoding.GetString(decrypted); //encode bytes back to string 
            for (int i = 0; i < decrypted.Length; i++)
            {
                Console.Write("{0}", dData[i]);
            }

        }
    }
}

这是一个普遍的要求，因此，互联网上有成千上万的文章/博客.

找到它们所需要做的就是想出一个合适的搜索词组并可以使用搜索引擎.

This is a common requirement and there are, therefore, thousands of articles/blogs on the internet.

All you have to do to find them is to think of a suitable search phrase and have access to a search engine.
