Sharing certificates with others
Businesses that use certificates for secure workflows often store certificates on a directory server that participants can
search to expand their list of trusted identities.
When you receive a certificate from someone, you can add it to your list of trusted identities. You can set your trust
settings to trust all digital signatures and certified documents created with a specific certificate. You can also import
certificates from a certificate store, such as the Windows certificate store. A certificate store often contains numerous
certificates issued by different certification authorities.
For complete information on sharing certificates, see the Digital Signatures Guide (PDF) at
Note: Third-party security providers usually validate identities by using proprietary methods. Or, they integrate their
validation methods with Acrobat. If you use a third-party security provider, see the documentation for the third-party
provider.
Get certificates from other users
Certificates that you receive from others are stored in a list of trusted identities. This list resembles an address book and
enables you to validate the signatures of these users on any documents you receive from them.

Add a certificate from a digital signature in a PDF

originator or the certificate.
