c# - 使用 RSACryptoServiceProvider.Decrypt(byte[], bool) 问题进行解密

Question

我在尝试使用指定的私钥解密 RSA 加密的字节数组时遇到了这个问题：基本上，在调用 .Decrypt() 方法之后，我得到的只是一个空字节数组（字节 [0]）。

这是代码：

static RSACryptoServiceProvider eng;
    static RSACryptoServiceProvider gne;

    static RSA()
    {
        eng = new RSACryptoServiceProvider();
        gne = new RSACryptoServiceProvider();
        eng.FromXmlString(xmlKKEY);
        gne.FromXmlString(xmlPKEY);
        eng.ImportParameters(eng.ExportParameters(true));
    }

    public static byte[] Encrypt(byte[] data)
    {
        return gne.Encrypt(data, false);
    }

    public static byte[] Decrypt(byte[] data)
    {
        byte[] d = eng.Decrypt(data, false);
        return d;
    }

由于请求，我已经包含了密钥 - 当时我使用 pepta.net 生成了它们：

    private readonly static string KKEY = @"
