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

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.

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 email

When a contact sends a certificate to you in email, it is displayed as an import/export methodology file attachment.

1 Double-click the email attachment, then click Set Contact Trust in the dialog box that appears.

2 Select the contact and click Import.

3 Supply any password required and click Next. Click OK to view the import details, and then click OK again.

Details and Trust information.

• For Trust, select the options desired.

• Use This Certificate As A Trusted Root only if it is required to validate a digital signature. Once you make a

certificate a trust anchor, you prevent revocation checking on it (or any certificate in the chain).

• To allow actions that can be a security risk, click Certified Documents, and then select the options you want to

allow:

Add a certificate from a digital signature in a PDF

You can safely add a certificate to your trusted identities from a signed PDF by first verifying the fingerprint with the

originator or the certificate.
