Verify certificate information
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 You can also check if the certificate has been revoked, which may occur due to employee departure or a security issue.
If you're unsure about the certificate’s authenticity, contact the certificate owner to verify the fingerprint (MD5 and SHA1 digest) values. For more information on verifying certificates, refer to the Digital Signatures User Guide.
Verify your own certificate
In the Identities & Trusted Certificates section, select More.
Select your digital ID, and then select Certificate Details.
Review the certificate information displayed.
Verify certificates for contacts
Open the Signature Panel and select the signature you want to verify.
In the Options menu, select Show Signature Properties.
Select Show Signer’s Certificate to view the certificate details.
