2 Select a contact, and click Details.
3 Select the certificate name, and click Edit Trust.
4 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.
5 Click OK twice, and then click Close.

Use directory servers to store user certificates
Directory servers are commonly used as centralized repositories of identities within an organization. As such, the
server acts as an ideal location to store user certificates in enterprises that use certificate encryption. Directory servers
help you locate certificates from network servers, including LDAP (Lightweight Directory Access Protocol) servers.
After you locate a certificate, you can add it to your list of trusted identities so that you don’t have to look it up again.
By developing a storage area for trusted certificates, you or a member of your workgroup can facilitate the use of
encryption in the workgroup.
