A digital signature is a mathematical technique used to validate the authenticity and integrity of a digital message, software, or document. It’s the digital equivalent of a handwritten signature or stamped stamp, but it offers much more inherent security. A digital signature is intended to solve the problem of manipulation and impersonation in digital communications.
Why is it important
Digital signatures are the most secure form of electronic signatures and the most reliable, making them ideal for confidential legal documents and contracts. Certification and authenticity information stored in a digital signature is very difficult to manipulate or falsify.
