TIP 145: Sharing and Importing Digital IDs

You can't open a document that has been signed by someone unless you have a copy of that individual's certificate. (Read about creating and customizing digital IDs in Tip 141.) Certificates you share with others are referred to as trusted identities. You can share your certificates with others working in a group or review process. Begin by choosing Advanced > Trusted Identities. The Manage Trusted Identities dialog opens.

Acrobat lets you display the contents of your identities list in one of two ways: by using contacts or by displaying certificates (Figure 145a). Contacts are formal FDF files you exchange with someone else. You request an FDF (signature) file by email, and your contact sends back his or her FDF file.

A contact is secure as you go through a formal data exchange process, but an extracted certificate is much quicker. Rather than having to email people and request their certificate, you just extract it from a document they have sent to you.

You can also ask others to share their certificates with you. Start the process in a similar way to the sharing process:

When you have assembled contacts and certificates, you can distribute a document to a restricted list of users. (Read about recipients in the sidebar "Naming Names" in Tip 147).
