What is a Digital Signature ?

A digital signature is a mathematical technique used to validate the authenticity and integrity of a digital document, message or software. It’s the digital equivalent of a handwritten signature or stamped seal, but it offers far more inherent security.

Digital signatures are like electronic “fingerprints.” They are a specific type of electronic signature (e-signature). In the form of a coded message, the digital signature securely associates a signer with a document in a recorded transaction.
