Dear Support Team
We have encountered the same problem as described in Signing with certificate and TSA using Aspose.PDF. Is there any update on this issue? As described in this ticket, when we sign PDF documents and specify a TSA, TSA’s certificate is used for signature instead of our own certificate. This is a show stopper for us. Could you please look into the issue and let us know if there is a workaround? Thank you very much

Dear Support Team,
I encountered the same problem described here and in “Signing with certificate and TSA using Aspose.PDF”.
When I sign a PDF using a signature certificate with the PdfFileSignature class (and the PKCS7 class), everything works fine. However, when I add TimestampSettings, instead of adding a timestamp to the signature with my certificate, a signature with the provider’s TSA certificate is added.
I have purchased a license and am using the latest version of Aspose.PDF .NET - 25.12.0.
I would like to ask you to fix this bug. I would be most happy if you could implement the GetImprint method, which would return the so-called imprint for the timestamp, and also the SetTimestampToken method. I have already programmed communication with TSA using the BouncyCastle library.
Thank you very much in advance. Your library is brilliant, and the only thing missing for my complete satisfaction are the timestamps.
