The signature of a certified or signed document is valid if you and the signer have a trust relationship. The trust level of the certificate indicates the actions for which you trust the signer.
To set the trust level:
- Choose File > Preferences > Signature and click Change Settings under Signing & Verifications.
- Check the option(s) in Windows Integration group to trust all root certificates in the Windows Certificate Store when validating signatures and certified documents.
Tip: You can specify the trust level for a specific certificate in Foxit PDF Editor Trusted Certificates list while adding and managing the trusted certificate. Please refer to Add Trusted Certificates and Manage Trusted Certificates for more information. If you configure different settings for the same certificate, settings with higher permissions will prevail. Remember that checking trust options may compromise security. Please make sure that you trust all the root certificates before enabling the features.
