RE: Digital Signatures Directly From CAC Card

community.appian.com/.../notary-seal-tools Notary Seal Tool will likely do this for you.

The CAC and other local client keys are not available through a browser interface without locally installed software and browser add-ins. For security purposes, the browser intentionally and rightfully blocks the certificate private keys from being accessible to the browser content.

However, you can have the Application, with a server side Certificate sign as a Notary (just like a physical notary) on behalf of the end user. So long as the end user is authenticated over SSL with their client cert to the application, the app has proof of authenticity (like you showing your driver's license to a physical notary). Then the App, acting as the Notary, can digitally sign with cryptographic integrity, on behalf of the end user. The Digital Signature is a completely valid digital signature and shows up with green checkboxes inside the PDF and stuff, BUT it is signed by the server side Notary private key on behalf of the SSL authenticated end user.

For reference this is how DocuSign (without local installs) works as well.

David L Did you end up building something? If so, I would be interested in talking to you about it. Thank you!
