Digital Signature
A digital signature is a mathematical approach for ensuring the integrity and validity of a message, software, or digital document. It's a digital version of a handwritten signature or a stamped seal, but it's significantly more secure. A digital signature is designed to address the issue of digital communications manipulation and impersonation. Digital signatures can be used to verify the origin, identity, and status of electronic documents, transactions, and messages. Signers can also use them to acknowledge their understanding of the situation. Digital signatures are legally enforceable in several nations, including the United States.
