Learn how to check the details of digital certificates in Adobe Acrobat to ensure their validity and trustworthiness.
Digital certificates include key details like the holder’s identity, validity period, usage, serial number, and public key method. You can also check if the certificate has been revoked, which may occur due to employee departure or a security issue.
