使用 RSA 加密的 C# 问题 [英] C# Problem encrypting using RSA

问题描述

我正在使用我从 MSDN 上撤下的这个功能

I am using this function which I pulled off MSDN

static public byte[] RSAEncrypt(byte[] DataToEncrypt, RSAParameters RSAKeyInfo, bool DoOAEPPadding)
        {
            try
            {
                byte[] encryptedData;
                //Create a new instance of RSACryptoServiceProvider.
                using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())
                {

                    //Import the RSA Key information. This only needs
                    //toinclude the public key information.
                    RSA.ImportParameters(RSAKeyInfo);

                    //Encrypt the passed byte array and specify OAEP padding.  
                    //OAEP padding is only available on Microsoft Windows XP or
                    //later.  
                    encryptedData = RSA.Encrypt(DataToEncrypt, DoOAEPPadding);
                }
                return encryptedData;
            }
            //Catch and display a CryptographicException  
            //to the console.
            catch (CryptographicException e)
            {
                Console.WriteLine(e.Message);

                return null;
            }

        }

我从这里调用方法:

 using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())
            {

                //Pass the data to ENCRYPT, the public key information 
                //(using RSACryptoServiceProvider.ExportParameters(false),
                //and a boolean flag specifying no OAEP padding.
                encryptedData = RSAEncrypt(dataToEncrypt, RSA.ExportParameters(false), false);

但我收到此错误消息:

Key not valid for use in specified state.

知道出了什么问题吗?

推荐答案

代码运行正常！！我试过了，我想你可能在解密时遇到了问题，因为你应该使用相同的密钥

The code works fine!! I tried it, I think you may have a problem in decryption as you should use the same keys
