- Product
- Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Setting up a digital ID for secure document signing using a Notarius digital certificate.
- Observed behavior
- Notarius ID files, such as EPF or XCC, appear unavailable or cannot be selected when attempting to manually import them during the Acrobat digital ID setup.
Ensure that your Notarius certificate is fully activated and correctly installed on your computer using the Entrust application before opening your PDF software.
Allow Acrobat to Auto-Detect the Certificate via Entrust
Avoid manual file imports by letting Adobe Acrobat automatically detect the Notarius certificate through your system's Entrust installation.
A common misconception is that you need to manually import EPF or XCC files into Adobe Acrobat to create a new digital ID. In reality, if your Notarius certificate is properly installed and managed by Entrust on your computer, Acrobat will automatically detect it.
Launch Adobe Acrobat Pro DC. Go to the 'Edit' menu (or 'Acrobat' menu on macOS) and select 'Preferences'. Click on 'Signatures' in the left-hand categories pane.
In the 'Identities & Trusted Certificates' section, click the 'More...' button. Check the list to ensure your Notarius certificate is automatically displayed under your digital IDs.
Open the PDF you wish to sign. Select the 'Certificates' tool from the tools menu, click 'Digitally Sign', drag a signature box, and select your Notarius certificate from the list of available system certificates.

Frequently Asked Questions
Do I need to manually import my Notarius EPF file into Acrobat?
No. Adobe Acrobat relies on the system's certificate store managed by Entrust for Notarius certificates. Manually importing EPF or XCC files into Acrobat's digital ID interface is generally neither required nor supported.
Can I use Adobe Sign with my Notarius certificate?
Yes. Once the Notarius certificate is correctly installed on your computer via Entrust, it is fully compatible with both Adobe Acrobat Pro DC and Adobe Sign for digital signature workflows.
Why isn't ConsignO working with my Notarius certificate on macOS 11?
There have been reported compatibility delays with specific versions of macOS (such as macOS 11) and the ConsignO software. However, you can bypass ConsignO entirely and use Adobe Acrobat to sign your PDFs, provided Entrust is properly installed.
