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.
For more information, see Digital Signature User Guide for Adobe Acrobat and Adobe Reader (PDF)
at www.adobe.com/go/learn_acr_security_en.
- Do one of the following:
In Acrobat, choose Advanced > Manage
Trusted Identities.
In Reader, choose Document > Manage Trusted Identities.
- Select a contact, and click Details.
- Select the certificate name, and click Edit Trust.
- In the Trust tab, select any of the following items to
trust this certificate for:
- Use This Certificate
As A Trusted Root
- Trusts signatures created directly by this certificate.
The root certificate is the originating authority in a chain of
certificate authorities that issued the certificate. By trusting
the root certificate, you trust all certificates issued by that
certificate authority.
- Signed Documents Or Data
- Acknowledges the identity of the signer.
- Certified Documents
- Trusts documents in which the author has certified the document
with a signature. You trust the signer for certifying documents,
and you accept actions that the certified document takes.
When
Certified Documents is selected, the following options are available:
- Dynamic Content
- Allows movies, sound, and other dynamic elements to play
in a certified document.
- Embedded High Privilege JavaScript
- Allows privileged JavaScript embedded in PDF files to
run. JavaScript files can be used in malicious ways. It is prudent
to select this option only when necessary on certificates you trust.
- Privileged System Operations
- Allows documents to use system operations, such as networking,
printing, and file access.
Note: Only allow Embedded High Privilege JavaScript and Privileged
System Operations for sources who you trust and work with closely,
such as your employer or service provider.
- Click OK twice, and then click Close.
