You must add the Certificates received from others to your Trusted Identities list so that you can verify their digital signatures in future documents. You can then also send encrypted files accessible only to them and other certified recipients.

To add a certificate to the Trusted Identities list:

  1. Choose Document > Trusted Identities.
  2. In the Manage Trusted Identities dialog box, click Browse.
  3. In the Open dialog box, browse to select a Certificate file and click Open.

Note: You should add your own Certificate to your Trusted Identities list so that you can handle the PDF documents you’ve secured or signed with your private key.
