+Summary: TlsClientCertificateVerify doesn't work with non exportable RSA
+The TtlCertificateVerify doesn't work with non exportabel RSA 
+For creating the signature the Private key is exported from the RSA and 
+imported in an RSAManaged class to create the signature. This is done 
+because the RSACryptoServiceProvider throws an NotImplementedException on 
+The RSA class i'm suplying uses a Encypher box. So the private key is not 
+Other classes then the RSACryptoServiceProvider are likely to implement 
+the DecryptValue method. I created a patch that tries to use the 
+CreateSignature method of the RSA if it is not a RSACryptoServiceProvider. 
+If it is an RSACryptoServiceProvider or the CreateSignature throws an 
+NotImplementedException the old way is still done.
