用的RSACryptoServiceProvider自己的公钥和私钥初始化 [英] RSACryptoServiceProvider initialize with own public key and private key
问题描述
我想用我自己的公钥和私钥来初始化的RSACryptoServiceProvider。
据我研究，要做到这一点的方法是调用构造函数以
的RSACryptoServiceProvider RSAalg =新的RSACryptoServiceProvider（cspParams）;
如上所示
cspParams。然而，当我看看MSDN的例子就使用它：
http://msdn.microsoft.com/en-us/library/ca5htw4f.aspx
我不明白他们设置专用的任何地方或公共密钥。仅使用KEYCONTAINER。当我没有cspParam创建的RSACryptoServiceProvider，那么它是默认设置为只使用公共密钥。我注意到这一点，当我检查类本身的PublicOnly变量，它是一个只读变量。
我的问题是我怎么初始化这个类，然后建立我自己的私钥和公钥。
中的服务器将使用私有密钥和客户端将有公共密钥。
我发现了什么是创建一个RSAParameter对象并设置就可以了.Exponent和.Modulus参数分别为公共和私有变量。
但我发现了一个丢失密码错误，因为我相信的RSACryptoServiceProvider没有用正确的构造进行初始化。
下面是我的一些代码。不要担心的BigInteger类，它只是一个实验。即使我使用与否，我得到了同样的错误。

}
//的EncryptedData = RSACSPSample.RSAEncrypt（dataToEncrypt，RSAP ，FALSE）;
//如果（的EncryptedData！= NULL）{
密码= ByteConverter.GetString（decryptedData）;
//}
字段是可怕的命名，这是混淆了你。在指数字段是真正的的公共的一个公共密钥指数。在私人的指数为私钥是 D 领域。
这不是你的错，MSDN文档吮吸。
I'm trying to initialize RSACryptoServiceProvider with my own public and private keys.
As far as I could research, the way to do this is to call the constructor with
RSACryptoServiceProvider RSAalg = new RSACryptoServiceProvider(cspParams);
cspParams as shown above. However, when I look at the msdn example on the use of it: http://msdn.microsoft.com/en-us/library/ca5htw4f.aspx
I don't see any place where they set the private or public keys. Only using a KeyContainer. When I create an RSACryptoServiceProvider without a cspParam, then it is by default set to only use a Public key. I notice this when I check the PublicOnly variable on the class itself and it is a read only variable.
My question is how do I initialize this class and then set my own private and public keys. The server will be using the private key and the client will have the public key.
What I found out is that creating an RSAParameter object and setting the .Exponent and .Modulus parameters on it as the public and private variables respectively.
But I'm getting a "Missing Private Key" error since I believe the RSACryptoServiceProvider isn't initialized with the correct constructor.
Below is some of my code. Don't worry about BigInteger class, it's just an experiment. Even if I use it or not, I get the same error.
//Create a UnicodeEncoder to convert between byte array and string.
UnicodeEncoding ByteConverter = new UnicodeEncoding();
byte[] dataToEncrypt = ByteConverter.GetBytes(password);
byte[] encryptedData;
byte[] decryptedData;
//RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
RSAParameters rsap = new RSAParameters();

using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())

The fields are horribly named and it is confusing you. The Exponent field is really the public exponent for a public key. The private exponent for a private key is the D field.
It is not your fault that MSDN documentation sucks.
