             <summary>
             This class allows you to sign with either an RSACryptoServiceProvider/DSACryptoServiceProvider from a X509Certificate2,
             or from manually created RSACryptoServiceProvider/DSACryptoServiceProvider.
             Depending on the certificate's CSP, sometimes you will not be able to sign with SHA-256/SHA-512 hash algorithm with 
             RSACryptoServiceProvider taken directly from the certificate.
             This class allows you to use a workaround in this case and sign with certificate's private key and SHA-256/SHA-512 anyway.
             
             An example of a workaround for CSP that does not support SHA-256/SHA-512:
             <code>
                        if (certificate.PrivateKey is RSACryptoServiceProvider)
                        {                
                            RSACryptoServiceProvider rsa = (RSACryptoServiceProvider)certificate.PrivateKey;
            
                            // Modified by J. Arturo
                            // Workaround for SHA-256 and SHA-512
            
                            if (rsa.CspKeyContainerInfo.ProviderName == "Microsoft Strong Cryptographic Provider" ||
                                            rsa.CspKeyContainerInfo.ProviderName == "Microsoft Enhanced Cryptographic Provider v1.0" ||
                                            rsa.CspKeyContainerInfo.ProviderName == "Microsoft Base Cryptographic Provider v1.0")
                            {
                                string providerName = "Microsoft Enhanced RSA and AES Cryptographic Provider";
                                int providerType = 24;
            
                                Type CspKeyContainerInfo_Type = typeof(CspKeyContainerInfo);
            
                                FieldInfo CspKeyContainerInfo_m_parameters = CspKeyContainerInfo_Type.GetField("m_parameters", BindingFlags.NonPublic | BindingFlags.Instance);
                                CspParameters parameters = (CspParameters)CspKeyContainerInfo_m_parameters.GetValue(rsa.CspKeyContainerInfo);
            
                                var cspparams = new CspParameters(providerType, providerName, rsa.CspKeyContainerInfo.KeyContainerName);
                                cspparams.Flags = parameters.Flags;
            
                                using (var rsaKey = new RSACryptoServiceProvider(cspparams))
                                {
                                    // use rsaKey now
                                }
                            }
                            else
                            {
                                // Use rsa directly
                            }
                        }

             <summary>
             This behavior is different in Java and .NET, because in Java we use this two-step check:
             first via #hasUnsupportedCriticalExtension method, and then additionally allowing standard critical extensions;
             in .NET there's only second step. However, removing first step in Java can be a breaking change for some users
             and moreover we don't have any means of providing customization for unsupported extensions check as of right now.
            
             During major release I'd suggest changing java unsupported extensions check logic to the same as in .NET,
             but only if it is possible to customize this logic.
