PAdES

PAdES (PDF Advanced Electronic Signatures) is a set of technical standards that ensure the security, authenticity, and integrity of PDF documents when they are signed electronically. It allows digital signatures to be added to PDFs in a way that proves the document hasn't been altered since signing. This makes PAdES suitable for official, legal, or business documents, providing confidence that the signer is genuine and the content remains intact. Essentially, PAdES combines digital security with the convenience of electronic signing, supporting trusted, verifiable digital transactions.
