Solution 1Recommended

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.

1
Open Signature Preferences

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.

2
Verify Approved Certificates

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.

3
Apply the Digital Signature

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.

ConsignO is Optional: You do not need to use ConsignO to sign documents if you are using Acrobat. As long as Entrust is running, Acrobat will successfully interact with your digital ID.

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.
