What is a Digital Signature?

Digital Signature is an electronic way to authenticate a document. It can be in the form of a certificate, email, or a computer. Using digital signatures saves time, money, and effort. Digital signatures are also secure. They can be used anywhere and on any device. In addition, they can be used to reduce the risk of phishing attacks.

The public key attribute on a digital signature makes it easy for others to validate the integrity of data. Authenticity is one of the most important components of a digital signature, as a tampered data or signature can lead to data compromise. To be valid, the hash value must match the value of a second computation of the same data.
