digital signature
Cryptographic identity proof
A digital signature is a cryptographic method for verifying the authenticity and integrity of electronic documents or messages.
Unlike a scanned handwritten signature, it uses mathematical algorithms to prove that content hasn't been altered and genuinely came from the claimed sender.
Digital signatures are legally binding in most jurisdictions and essential for secure online transactions: The contract requires a digital signature before processing.
