I agree OpenPGP smartcard/token support is a must have, and brought this
up during this during this weekend's OpenPGP summit; please see the
[notes] section "Workshop: Thunderbird & OpenPGP" for some of the
discussion, specifically
Although RNP doesn't support smartcards currently, a potential solution
was suggested by Kristian and Andre: talking to SCDaemon (scd) with IPC.
Details need to be discussed, but it would be an optional solution, that
only works if the user has installed software (scd etc.) in addition to
Thunderbird. How would this work? GnuPG as an optional dependency?
Outsourcing smartcard handling to scdaemon (scd), which is available
cross-platform through Unix socket or TCP/IP (windows) with usual user
system protection? Or... extend the RNP library to talk to scd? Needs
discussion and contributors, but that should wait until we're certain
what library TB will use.
