.net核心RSA pem如何转换为xml？

Question

最近我有项目需要在.net core 1.1上运行它。我意识到RSACryptoServiceProvider不在.net核心RSA类上。

在我在stackoverflow中搜索后，只有很少的结果如下=>

如何在.net Core中使用RSA

如何从.NET读取PEM RSA私钥

C＃将私有/公共RSA密钥从RSACryptoServiceProvider导出到PEM字符串

这是上面的帖子提示我下面的链接

https://gist.github.com/brentmaxwell/46081df6fcbc0ca33fe1

我也研究了BouncyCastle PCL 1.8.1.1。我仍然无法解决

任何一种都可以帮助将以下pem格式转换为.net core中的XML格式。

来自https://superdry.apphb.com/tools/online-rsa-key-converter的结果 是有效的。但是bouncyCastle .net核心示例代码并不多

Answer 1

   PemReader pr = new PemReader(new StringReader(File.ReadAllText(pemfilepath)));
   RSAParameters rsaParams = pr.ReadPrivatekey();
   string gitHubAppIdentifier = appidentifier;
   var rsaProvider = new RSACryptoServiceProvider();
   rsaProvider.ImportParameters(rsaParams);
   var key = new RsaSecurityKey(rsaProvider);
