  • 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.

    Sending and Receiving Certificates

    You can automatically include your certificates to add to your contact's list of trusted identities. Just click Include My Certificates. If you click this option, you have to choose a signature profile and enter your password in order to include the information in the email.

    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.

    Figure 145a. To create your Digital ID list, select either contacts or certificates to exchange with others.

    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.

    1.

    Select a certificate or contact from the list to send that person your certificate information, or to save a copy of your certificate to your hard drive or other storage location, and then click Export. The Data Exchange File - Exporting Contact Information dialog opens (Figure 145b).

    Figure 145b. In this dialog, define how you want to export the certificate information.

    What's in a Name?

    Be careful naming signatures and choosing passwords. Name the signature in a form that is recognizable to both you and any recipients you may share the profile with. For example, dbaker is understandable to me (it's my name!) and to those I share the certificate with. On the other hand, naming a profile General or Magazine isn't useful to anyone but me. If you use certificates for different workgroups or situations, develop a naming system. dbaker_basic is useful both to me and to my recipients, although the name is a little lengthy. Use the same caution with passwords, and be sure to use character strings you can easily remember.

    2.

    Choose the email radio button to export the data file, or choose the Save the data to a file radio button and select a file type to export the information. In either case, a series of wizard screens will walk you through the process.

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

    1.

    Choose Advanced > Trusted Identities. The Manage Trusted Identities dialog opens as shown in Figure 145a.

    2.

    Click Request Contact. The Email a Request dialog opens.

    3.

    Type your name and email address. You can choose to email the request or save it as a file to send later. Click Next and proceed through the wizard-like dialogs.

    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).
