Digital Certificate : To add Digital signature on a PDF #561

Closed BhanuuPrakash closed 3 months ago

BhanuuPrakash commented 3 months ago

Hello UniDoc Team,

We are currently integrating digital signatures into our PDF documents using UniPdf and need guidance on obtaining a digital certificate. Our goal is to ensure that the attached digital certificate can be validated by the end users for authenticity and security.

Specifically, we are looking for recommendations on: A Certificate Authority (CA) that provides digital certificates suitable for document signing.

Thank you for your assistance!

Welcome! Thanks for posting your first issue. The way things work here is that while customer issues are prioritized, other issues go into our backlog where they are assessed and fitted into the roadmap when suitable. If you need to get this done, consider buying a license which also enables you to use it in your commercial products. More information can be found on https://unidoc.io/
