Digital signatures are authenticated in this manner. If the recipient is unable to open the document using the signer's public key, there is a problem with the document or the signature. The person who creates the digital signature encrypts signature-related data with a private key, and the only way to decrypt that data is with the signer's public key. Two keys are generated using a public key algorithm, such as RSA (Rivest-Shamir-Adleman), resulting in a mathematically linked pair of keys, one private and one public.ĭigital signatures are created using two mutually authenticating cryptographic keys in public key cryptography. Public key cryptography, also known as asymmetric cryptography, underpins digital signatures. They can also be used by signers to acknowledge informed consent.ĭigital signatures are legally binding in many countries, including the United States, in the same way that traditional handwritten document signatures are. A digital signature is designed to prevent tampering and impersonation in digital communications.ĭigital signatures can be used to verify the origin, identity, and status of electronic documents, transactions, or digital messages. It's the digital equivalent of a handwritten signature or a stamped seal, but it's far more secure. Before diving into PAdES format, lets recap what is a digital signature.Ī digital signature is a mathematical technique for validating the authenticity and integrity of a message, piece of software, or digital document.
