生成公私密钥对，并显示他们在asp.net文本框 [英] Generate public-private key pair and show them in textbox in asp.net

问题描述

任何机构可以解释RSAParameters参数
我曾见过像P，D，E，Q参数，...
我需要从它的私钥和公钥

any body can explain the parameters of RSAParameters i had seen the parameters like p,d,e,q,... i need the private key and public key from it

我现在用的样品code作为这样的
可任何人都可以说，这是正确与否
样品code：

i am using the sample code as like this can anybody can say it was right or not sample code:

  //Generate a public/private key pair.
            RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
            //Save the public key information to an RSAParameters structure.
            RSAParameters RSAKeyInfo = RSA.ExportParameters(true);
            //public key    
            TextBox5.Text = Convert.ToBase64String(RSAKeyInfo.Exponent);
            // private key  
            TextBox6.Text = Convert.ToBase64String(RSAKeyInfo.D);

他们得到为，该
公钥是{E，N}其中n =（P * Q）的结果
私钥{D，N}其中n =（P * Q）的结果。

they had give as that the public key is {e,n} where n = result of the (P*Q) Private key is {d, n} where n = result of the (P*Q)

在那里我有做的是正确的事情，或没有在样品code的公钥和私钥

where i had done is the correct thing or not in the sample code for the public and private keys

很多

推荐答案

使用BouncyCastle的API

Using the BouncyCastle API

http://www.bouncycastle.org/

和以下类似的东西;

public AsymmetricCipherKeyPair GenerateKeys(int keySizeInBits)
{
  RsaKeyPairGenerator r = new RsaKeyPairGenerator();
  r.Init(new KeyGenerationParameters(new SecureRandom(),
    keySizeInBits));
  AsymmetricCipherKeyPair keys = r.GenerateKeyPair();
  return keys;
}

您可以访问的对象，将有一个公开和私人属性与正确格式化字符串。

You can access an object that will have a .Public and .Private property with the correctly formatted strings.

我有一个类似的问题而回，这是我能找到的最好的解决方案。我没有确切的code出手，而是将发布它，当我进入办公室，如果需要，但上面的应该工作。

I had a similiar problem a while back and this was the best solution that I could find. I do not have the exact code to hand, but will post it when I get into the office if required, but the above should work.

更新，其中code

这是code我用来生成公钥/私钥。

This is the code I used to generate public/private keys.

  public static AsymmetricCipherKeyPair GenerateKeys(int keySizeInBits)
    {
        var r = new RsaKeyPairGenerator();
        r.Init(new KeyGenerationParameters(new SecureRandom(),keySizeInBits));
        var keys = r.GenerateKeyPair();
        return keys;
    }



static void Main(string[] args)
{
    var keys = GenerateKeys(2048);


    var publicKey = keys.Public.ToString();

    var textWriter = new StreamWriter("private.key");
    var pemWriter = new PemWriter(textWriter);
    pemWriter.WriteObject(keys.Private);
    pemWriter.Writer.Flush();
    textWriter.Close();


    textWriter = new StreamWriter("public.key");
    pemWriter = new PemWriter(textWriter);
    pemWriter.WriteObject(keys.Public);
    pemWriter.Writer.Flush();
    textWriter.Close();

    Console.ReadKey();


}
