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 Document Security User Guide For Adobe Acrobat and Adobe Reader (PDF) at www.adobe.com/go/learn_acr_security_en. 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.
