Sign PDF document with cert from store in C# using Aspose.PDF for .NET

@Lebesgue

Thanks for getting back to us.

We have also investigated the logged ticket and found that the current hex string for X502Certificate2 did not contain private key and, therefore, could not be used for signing document. You should export certificates with both of the keys i.e. public and private.

And that is connected with other issue reported?

@Lebesgue

The other part of the issue is currently pending for investigation. Its investigation is planned after release of 20.2 version of the API. We will let you know as soon as we have some updates in this regard. Please spare us some time.
