Verify information on a certificate
The Certificate Viewer dialog box provides user attributes and other information about a certificate. When others
import your certificate, they often want to check your fingerprint information against the information they receive with
the certificate. (The fingerprint refers to the MD5 digest and SHA1 digest values.) You can check certificate
information for your own digital ID files or for ID files that you import.
For more information about verifying certificates, see Digital Signature User Guide for Adobe Acrobat and Adobe
Reader (PDF) at
.
The Certificate Viewer dialog box provides the following information:
•
The certificate validation period
•
The intended use of the certificate
•
Certificate data, such as the serial number and public key method
You can also check if the certificate authority has revoked the certificate. Certificates are typically revoked when an
employee leaves the company or when security is compromised in some way.

Set the trust level of a certificate
In Acrobat or Reader, the signature of a certified or signed document is valid if you and the signer have a trust
relationship. The trust level of the certificate indicates which actions you trust the signer for.
You can change the trust settings of certificates to allow or disallow specific actions. For example, you can change the
settings to enable the dynamic content and embedded JavaScript within the certified document.
