I am evaluating Aspose.PDF as one of HTML, MS Office to PDF conversion libraries.
We plan to use digital signatures and certifications. Does your product support digital signatures with external HSM (like Azure KeyVault)?
Do you support certifications (instead of digital signatures)?
Thank you for contacting support.
Aspose.PDF for .NET API supports signing a PDF file using smart card as well as certificates. However, we are afraid that signing with external key, like Azure KeyVault may not be available at the moment. You may visit below documentation articles for your kind reference.
