How to validate a digital signature in a PDF

0 votes
In my project, I need to verify digital signatures in PDF files to ensure document authenticity. How can I programmatically validate a digital signature in a PDF, and are there libraries that can assist with this? What specific steps should I follow to confirm a signature's validity?

Guidance on using tools or code to verify PDF digital signatures would be appreciated.
