Hi Support,

See attached MS Word document, we are failing to convert it into PDF and receiving following error:

“SignatureDescription could not be created for the signature algorithm supplied.”

We are using following code for PDF conversion

Aspose.Words.Document Document = new Aspose.Words.Document(InputFileName);
Aspose.Words.Saving.PdfSaveOptions PdfSaveOptions = new Aspose.Words.Saving.PdfSaveOptions();
PdfSaveOptions.Compliance = Aspose.Words.Saving.PdfCompliance.PdfA1b;

MemoryStream Stream = new MemoryStream();
Document.Save(Stream, PdfSaveOptions);

Kindly let us know what could be reason in this case.

Regards,
Wahaj Khan

Hi Tahir,

Show signature appearance in generated PDF is also part of our important requirement so removing signatures from document is not feasible for us.

Kindly do let us know once this fixed.

Hi Wahaj,

Thanks for your inquiry via live chat.

We do understand your situation, however I am afraid, at the moment we can’t provide you the ETA for this issue. I have spoken to the responsible developer about your issue and I am afraid he is unable to commit any ETA at the moment.

Normally when an issue is reported by a customer it is added to the pool of current issues being worked on by our developers is analysed in a timely manner. However due to the nature of some bugs and the number of features we are working on, this doesn’t always mean we can fix every bug within a short time after it’s reported.

Thanks for your patience and understanding.
