我想基于PEM文件创建X509Certificate2对象。问题是设置X509Certificate2的PrivateKey属性。我在.NET Core上阅读X509Certificate2.CreateFromCertFile() ,然后使用
var rsa = new RSACryptoServiceProvider();
rsa.ImportCspBlob(pvk);

pvk私钥的字节数组在哪里(从GetBytesFromPEM读取,如此处所示,如何从PEM文件获取私钥?)来设置私钥,但随后我得到了一个
Internal.Cryptography.CryptoThrowHelper + WindowsCryptographicException,带有消息提供程序错误版本。
如何根据PEM文件中的私钥正确设置X509Certificate2的私钥?
如果我看创建X509Certificate2,他们使用
RSACryptoServiceProvider prov = Crypto.DecodeRsaPrivateKey(keyBuffer);
certificate.PrivateKey = prov;

这似乎是一种整洁的方法,但这在.Net Core中不起作用...
我目前正在 Java 上进行 RSA 加密,我必须使用私有和公共模数进行加密。我目前有以下几点:

var payload = JsonHelper.Serialize(new { iss = teamId, iat = ToEpoch(DateTime.UtcNow) });

虽然这在 Windows 上运行良好,CngKey.Import但在 Linux 和 MacOS 上不受支持。如何重写此代码以使其跨平台?
6号线和8号线有什么区别?它们都打印相同的字符串。为什么我们需要在StringBuilder中使用toString。
StringBuilder s = new StringBuilder("hello");//line1
System.out.println(s);//line2
s.append("hi");//line3
System.out.println(s);
s.append("okk");
System.out.println(s);//line 6
s.toString();
System.out.println(s);//line 8
