What is certificate verification?

Certificate verification is the process of validating the authenticity and integrity of a digital certificate, which is used to establish secure connections and identity in online communications. This involves checking the certificate's validity period, confirming it is issued by a trusted Certificate Authority (CA), and ensuring it has not been revoked. Through certificate verification, users can ensure that the entities they are communicating with are who they claim to be, thereby protecting against fraud and man-in-the-middle attacks.
