FAQ

What is the difference between certificate encryption and password encryption?

  1. Certificate encryption uses a digital certificate to protect the file and is suitable for scenarios that need stronger identity-based control.
  2. Password encryption mainly relies on a password to control access and is simpler to use.
  3. If your PDF workflow needs certificate-based access control, choose certificate encryption.

How can I get a digital certificate?

  1. You can obtain a digital certificate from a certificate authority.
  2. You can also use a certificate provided by your organization.
  3. After you get the certificate, confirm that its file format and password can be used for import and verification.

Can I remove certificate encryption later?

  1. Yes. You can use the corresponding certificate to decrypt the document or change its encryption settings.
  2. Before you do that, confirm that the current environment still has access to the corresponding certificate.
  3. If the certificate has been updated or changed, check its status before modifying the file.
