PAdES (PDF Advanced Electronic Signatures)

PAdES (PDF Advanced Electronic Signatures) is a set of technical standards that ensure digital signatures on PDF documents are secure, legally valid, and tamper-evident. It enables the signing of PDFs in a way that confirms the signer’s identity and protects the document from unauthorized changes after signing. PAdES helps organizations and individuals confidently share legally binding digital documents, providing assurances of authenticity and integrity, much like a traditional handwritten signature but with digital security features embedded directly into the PDF file.
