I'm a security researcher who wants to integrate quantum -safe cryptographic signatures into Adobe PDF documents as part of my thesis.
How can I edit / amend the Adobe signature product to carry over this data, and ideally carry other metadata that I package (driver's license etc)?
My other option is to leverage Microsoft Word, but would rather focus on PDFs due to their wide usage.
Have you read ISO 32000-1 on this subject?
It sounds like you're going to need a custom signature handler plugin. There are examples in the Acrobat SDK.
