rsa 异常

[leyou240]

请问我的使用方式有问题吗？异常如下
Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException : 该项不存在。
at System.Security.Cryptography.CngKeyLite.ExportKeyBlob(SafeNCryptKeyHandle keyHandle, String blobType)
at System.Security.Cryptography.RSAImplementation.RSACng.ExportKeyBlob(Boolean includePrivateParameters)
代码如下

[Fact(DisplayName = "Rsa from pem test")]
        public void Rsa_From_Pem_Test()
        {
            //Act
            var pemPublicKey = @"

修改此方法运行成功！我提个pr

        public static RSAKey CreateRsaKey(RSA rsa, bool includePrivate = true)
        {
            Check.Argument.IsNotNull(rsa, nameof(rsa));

            string publicKey = rsa.ToJsonString(false);


            var rsaKey = new RSAKey()
            {
                PublicKey = publicKey,

                Exponent = rsa.ExportParameters(false).Exponent.ToHexString(),
                Modulus = rsa.ExportParameters(false).Modulus.ToHexString()
            };

            if (includePrivate)
            {
                string privateKey = rsa.ToJsonString(true);
                rsaKey.PrivateKey = privateKey;
            }
            return rsaKey;
        }
