Sharing and managing certificates
Sharing certificates with others
Your digital ID includes a certificate that others require to validate your digital signature and to encrypt documents
for you. If you know that others will need your certificate, you can send it in advance to avoid delays when
exchanging secure documents. Businesses that use certificates to identify participants in signing and secure
workflows often store certificates on a directory server that participants can search to expand their list of trusted
identities.
If you use a third-party security method, you usually don’t need to share your certificate with others. Third-party
providers may validate identities using other methods, or these validation methods may be integrated with Acrobat.
See the documentation for the third-party provider.
When you receive a certificate from someone, their name is added to your list of trusted identities as a contact.
Contacts are usually associated with one or more certificates and can be edited, removed, or reassociated with
another certificate. If you trust a contact, you can set your trust settings to trust all digital signatures and certified
documents created with their certificate.
You can also import certificates from a certificate store, such as the Windows certificate store. A certificate store may
contain numerous certificates issued by different certification authorities.

5 Do one of the following:
• Select Email The Data To Someone, and click Next to send your certificate as an FDF file to another user. Type the
email address, click Email, and then send the email message that appears in the default email application.
• Select Save The Data To A File, and click Next. Choose a file type from the menu, specify a name and location for
the file, and click Save.
Get certificates from other users
You keep certificates that you receive from other users in a list of trusted identities. This list is like an address book
that stores certificates. It lets you validate the signatures of these users on any documents you receive. You can also
use the list to encrypt files.
