Can a pdf file be signed using a usb token on Linux-based distributions?

[Alex Chamba]

I tried the latest version of JsignPdf in Windows and when signing pdf files using usb token devices there is no problem. I would like to know if in Linux based distributions there is also how to sign pdf files using a usb token.

Thanks in advance for the help.

Sure, it's possible. I'm using Linux primarily. You just need to use
the proper driver & config file for PKCS#11.

E.g. For my yubikey I use the following content of pkcs11.cfg:

name=OpenSC
library=/usr/lib/x86_64-linux-gnu/opensc-pkcs11.so
slotListIndex=1

Use the following java argument to enable PKCS#11 debug output
"-Djava.security.debug=sunpkcs11". You will get a better insight into
what's happening (or failing).

Just make sure to use java version 8 as jsignpdf will not be able to use PKCS11
