RSA加密中的“连接到系统的设备不起作用”错误是什么？

问题描述

使用RSA并希望使用JAVA中的公共密钥进行加密，并希望使用公共和私有密钥在c＃中进行解密。

加密在Java中工作正常，但在C＃中解密存在此错误： “连接到系统的设备不起作用”，这是什么意思？

Java加密方法：

static String publickey = "2rRVVVFJRbH/wAPDtnwZwu+nxU+AZ6uXxh/sW+AMCBogg7vndZsnRiHoLttYYPqOyOhfgaBOQogrIfrKL4lipK4m52SBzw/FfcM9DsKs/rYR83tBLiIAfgdnVjF27tZID+HJMFTiI30mALjr7+tfp+2lIACXA1RIKTk7S9pDmX8=";

static String Encrypt(String encodedString) {
      try {
        byte[] modulusBytes = Base64.getDecoder().decode(publickey);
        byte[] exponentBytes = Base64.getDecoder().decode("AQAB");
        BigInteger modulus = new BigInteger(1,modulusBytes);
        BigInteger exponent = new BigInteger(1,exponentBytes);

        RSAPublicKeySpec rsaPubKey = new RSAPublicKeySpec(modulus,exponent);
        KeyFactory fact = KeyFactory.getInstance("RSA");
        PublicKey pubKey = fact.generatePublic(rsaPubKey);

        Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
        cipher.init(Cipher.ENCRYPT_MODE,pubKey);

        byte[] plainBytes = new String("big kitty dancing").getBytes("UTF-8");
        byte[] cipherData = cipher.doFinal(plainBytes);
        String encryptedString = Base64.getEncoder().encodeToString(cipherData);

        return encryptedString;
    } catch (InvalidKeySpecException | NoSuchAlgorithmException | NoSuchPaddingException |
            InvalidKeyException | BadPaddingException | IllegalBlockSizeException | UnsupportedEncodingException err) {
    }
    return "Error";
}

C＃解密方法：

   static string Decrypt()
    {
        const int PROVIDER_RSA_FULL = 1;
        const string CONTAINER_NAME = "Tracker";

        CspParameters cspParams;
        cspParams = new CspParameters(PROVIDER_RSA_FULL);
        cspParams.KeyContainerName = CONTAINER_NAME;
        RSACryptoServiceProvider rsa1 = new RSACryptoServiceProvider(cspParams);
        //string str = rsa1.ToXmlString(true);


        rsa1.FromXmlString("<RSAKeyValue><Modulus>2rRVVVFJRbH/wAPDtnwZwu+nxU+AZ6uXxh/sW+AMCBogg7vndZsnRiHoLttYYPqOyOhfgaBOQogrIfrKL4lipK4m52SBzw/FfcM9DsKs/rYR83tBLiIAfgdnVjF27tZID+HJMFTiI30mALjr7+tfp+2lIACXA1RIKTk7S9pDmX8=</Modulus><Exponent>AQAB</Exponent><P>+lXMCEwIN/7+eMpBrq87kQppxu3jJBTwztGTfXNaPUTx+A6uqRwug5oHBbSpYXKNDNCBzVm/0VxB3bo4FJx+ZQ==</P><Q>yasOGaJaE9xlF9T2xRuKeG9ZxCiyjhYaYB/mbtL+SIbtkRLi/AxaU4g2Il/UxhxhSXArKxIzV28zktispPJx1Q==</Q><DP>ueRgQIEFUV+fY979a1RgrVHIPpqEI1URhOMH3Q59oiXCcOumM5njyIHmWQxRAzXnG+7xlKXi1PrnRll0L4oOKQ==</DP><DQ>dfEMNgG1HJhwpxdtmqkYuoakwQvsIRzcIAuIAJh1DoWaupWJGk8/JEstHb1d+t7uJrzrAi2KyT/HscH2diE0YQ==</DQ><InverseQ>YoYF9PF6FiC0YngVeaC/eqt/ea8wMYNN3YO1LuzWpcy2exPRj2U0ZbWMvHXMUb4ea2qmhZGx1QlK4ULAuWKpXQ==</InverseQ><D>g1WAWI4pEK9TA7CA2Yyy/2FzzNiu0uQCuE2TZYRNiomo96KQXpxwqAzZLw+VDXfJMypwDMAVZe/SqzSJnFEtZxjdxaEo3VLcZ1mnbIL0vS7D6iFeYutF9kF231165qGd3k2tgymNMMpY7oYKjS11Y6JqWDU0WE5hjS2X35iG6mE=</D></RSAKeyValue>");

        string data2Decrypt = "pt0DMKQM34rIp/aw64NBRhj8HZlp31i3Nu/9SP6o2Iwl9plu8k1TDbe04cQRkIDx/h6hsAKM0j13HdauidnEEvtm0yp9WrOMGut2XJUTUxWt5/y4bosm06tYtfw5HnlNHMMBtY22caCppwfdOJbiwp9rwEtWV9tXHU7VMenlVuw=";

        byte[] encyrptedBytes = Convert.FromBase64String(data2Decrypt);
        //Error occured in this line
        byte[] plain = rsa1.Decrypt(encyrptedBytes,false); 
        string decryptedString = System.Text.Encoding.UTF8.GetString(plain);
        return decryptedString;
    }
