What Is a Digital Signature?

February 7, 2024

A digital signature is a mathematically generated digital code that verifies the authenticity and integrity of documents or digital messages. The process uses a public and private key pair (asymmetric cryptography), a signing algorithm, and a signature verifying algorithm to ensure secure communication over insecure channels.

The encryption method is a standard in most cryptographic protocols. It is used in cases where it’s important to detect forgery, such as financial transactions.
