After certifying a PDF, Acrobat will display a blue ribbon in the document’s toolbar to indicate the document is certified and show any allowed changes.
This runs in the Acrobat app - there is no separate API for this task.
Certifying a PDF is a special type of signature that can only be the first signature on a document. It locks the document from further changes and shows it has been reviewed. Adding a digital signature is more general; it can be applied to a document that already has other signatures and mainly confirms the signer's identity.
Certifying a PDF is meant to be the first and most powerful statement about a document's authenticity and integrity. If other signatures were already present, the certification could not guarantee the state of the document before those signatures were added. It ensures the certification is the foundational trust mark.
No, the Adobe PDF Electronic Seal API is designed for applying organizational seals, not for personal digital IDs. This API is for businesses to apply official seals that comply with standards like eIDAS. It uses third-party certificate credentials and seal images, which is different from an individual's personal e-signature or digital ID for certifying a document.
