A digital signature is a cryptographic technique used to validate the authenticity and integrity of a digital message or document. It functions similarly to a handwritten signature but provides a higher level of security by using a pair of keys: a private key for signing and a public key for verification. This ensures that the message has not been altered and confirms the identity of the sender. Digital signatures are widely used in various applications, including email communication, software distribution, and legal agreements.
