How do I set up a Digital ID for my signature using my Yubikey security token?

Report · Aug 26, 2017

I would like to set up my Dgital ID for use in Adobe forms where a signature is required and would like to use my Yubikey for this.

When I select Smart Card or hardware token Adobe can not find the modules or drivers required.

Appreciate any help you can offer.

I know this post is old but in case any one is curious.

Here's how to set up a digital ID on a YubiKey and then use it in Adobe Acrobat:
1. Generating or Importing a Digital Certificate:

Before you can use a YubiKey with Adobe Acrobat, you'll need to generate or import a digital certificate. Here's how you can do this using the YubiKey Manager, which is the official YubiKey application for managing your device:

Download and install YubiKey Manager from Yubico's official website. For macOS (brew install --cask yubico-yubikey-manager)
Download and install OpenSC open source smart card tools and middleware. For macOS (brew install --cask opensc)
Launch YubiKey Manager and insert your YubiKey into a USB port.
Navigate to the "Applications" -> "PIV" -> "Certificates".
Under the "Digital Signature" section, click "Generate" to create a new certificate. Follow the prompts to complete this process (I used Self-signed certificate but you can use Certificate Signing Request (CSR), it's pricey)

2. Configuring Adobe Acrobat to use the YubiKey:

After you have a certificate on your YubiKey, you can configure Adobe Acrobat to use it:

Launch Adobe Acrobat and go to "Acrobat" -> "Preferences..." -> "Signatures" -> "Identities & Trusted Certificates" -> "More".
Click on "PCS#11 Modules and Tokens" under "Digital IDs"
Click "Attach Module" and paste in the path: /Library/OpenSC/lib/opensc-pkcs11.so
At this point, Acrobat should detect your YubiKey Digital Signature. (BTW, the default Yubikey PIN is 123456)

Your instructions were very clear. I followed them precisely (former BSEE). Until I got to the very last bullet everything was good. "Acrobad should detect"....but doesn't. I click on the "use signature device" and I get the error "Acrobat cannot find any new Digital IDs"...help.
