First conclusion, signing doesn't work in Foxit Readerġ7. I repeat from step 4, twice, for both certificates. I unlock the certificates through Keychain Access (enter PIN) and leave the card inserted (so certificates are unlocked for some minutes)ġ5. Repeat from step 5 twice, for both certificates, Same resultġ4. I run Keychain Access (stock utility application of macOS), change both certificates trust from "System Default" to "Always trust" for all categories, then remove the smart card, reboot, reinsert the card, run Keychain Access again and check, the trust setting is now "Always Trust" for both certificates.ġ2. I unplug the reader, quit Foxit and repeat from step 2, selecting lower certificate. I unplug the reader, quit Foxit and repeat from step 2, selecting upper certificate. I repeat from step 5, only I use the other (upper) certificate.
After reboot, I go back to step 2, everything is the same, including the error messageĨ.
#PDF SIGNATURE PROBLEM MAC#
I disconnect the smart card reader and reboot the Mac (BTW, this instruction is completely wrong, on a Mac this *NEVER* helps, it's not Windows)ħ. I select the lower cerificate (for signing) and click OK, The dialog disappears and an alert pops up immediately:Ħ. The Select Certificate dialog box shows this In theSelect Certificate dialog box, select the digital ID file, specify the selection preference, and click OK.(Optional) If you choose not to sign document immediately after the signature is placed, click on the signature field you drawn to continue.Press and hold the mouse button down, and drag to draw a signature field for your signature.Click Protect > Sign & Certify > Place Signature.

Following steps from Foxit Reader User Manual
#PDF SIGNATURE PROBLEM PDF#
PDF document opened using Foxit Reader (which is NOT default application for PDF)ĥ. smart card inserted, green LED lights up steadilyĤ. smart card reader plugged into USB, the reader green LED flashesģ. first signing attempt usually fails, but only when attempting to save the signed document, and the next attempt immediately after is successful. Signing PDF documents works erratically when I use the same setup with latest available Adobe Reader (2021.001.20155). There are two certificates on the card, one for identification only, and the other for signing. Smart card is standard contact-chip card bearing digital identity certificates and keys compliant to EU Regulation 910/2014 MacOS is 10.13.6 running on MacBookPro 15" Mid2015 with dual graphics and 16GB RAM On any Acrobat XI, though, the message presumably will become "At least one signature has problems" again because Adobe meanwhile has started supporting PAdES subfilters.I'm trying to place a digital signature using a digital identity certificate from a smart car through Foxit Reader for macOS into a PDF document created by LibreOffice Writer built-in PDF generator, and it consistently fails at first step. I've changed the subfilter from CMS to CADES and the message changed from "At least one signature has problems" to "At least one signature requires validating".
If it does not know the SubFilter, it does not try to verify. If it knows the SubFilter but not the Filter, it does not try to verify automatically but at least offers to verify If the Reader / Acrobat knows them, it automatically tries to verify the signature (unless the configuration settings were changed). Whether or not Adobe Reader / Acrobat tries to verify a signature depends on the Filter and SubFilter entries of the signature dictionary: At least one signature has problems implies that Adobe Acrobat has tried to verify the signature but failed doing so.Īt least one signature requires validating implies that Adobe Acrobat has not tried to verify the signature and, therefore, has not yet decided whether it would fail or not.
