Hello,
does this mean `epa-file-cache-passphrase-for-symmetric-encryption' can
work with GnuPG 2.1? Do you plan to enable that functionality?
Thanks
Ted

Apparently, I missed Cc: to the list. Resending with a bit more info,
for those interested.

With GnuPG 2.1, the variable is even not necessary anymore. When you set
epa-pinentry-mode to loopback, gpg-agent (now internally invoked by gpg)
talks to Emacs. That means the passphrase you input from the minibuffer
will be cached in the gpg-agent's cache.
If you are on Debian sid, you can try it with:
- install GnuPG 2.1 package from experimental:
$ apt-get install gnupg2/experimental
- add 'allow-loopback-pinentry' to ~/.gnupg/gpg-agent.conf
$ echo allow-loopback-pinentry >> ~/.gnupg/gpg-agent.conf
- set epg-gpg-program to "gpg2" and also epa-pinentry-mode to 'loopback
Regards,
