Code examples
The test code can be found in the snapd repository:
https://github.com/snapcore/snapd/blob/master/interfaces/builtin/pkcs11_test.go
The source code for the interface is in the snapd repository:
snapd/interfaces/builtin/pkcs11.go at master · canonical/snapd · GitHub
I’m trying to figure out how this is supposed to work.
I am one of the people who maintain the official Belgian eID middleware, which (amongst other things) ships a PKCS#11 module.
Enabling the pkcs11 interface for firefox does not work. On plucky, using the “latest/edge” snap, I get:
wouter@ubuntu-test:~$ snap connect firefox:pkcs11
error: snap "firefox" has no plugin named "pkcs11"
I assume this means that PKCS#11 support for the firefox snap is not enabled. Is this correct? If not, what do I need to do?
Additionally, once I manage to connect the PKCS#11 interface to Firefox, I assume I need to go through some special steps to make my PKCS#11 module available for use in snaps? I have it registered with p11-kit, is that sufficient? If not, what other steps would I need to do?
The documentation here is very limited and not at all clear for someone in my position who wants to make things work 
Thanks.
Sorry for the delay getting back to you. I’m going to put this question to the team, and I totally agree what we need to provide much more information for these interface pages with only the bare minimum.
