I've been using org.gpg files for a while for encrypting information
and everything works just fine.  However, trying to add such a file to
my org-agenda-files list means I end up having to type in my passphrase
quite often.  I know that EPA will allow caching of passphrases but this
is discouraged for security reasons.  Instead, one is advised to use
gnupg-agent.  

Does anybody have any experience with gnupg-agent?  It's working, in
that I get prompted for my passphrase and the files are decrypted (or
encrypted, as the case may be) but my passphrase is not cached.  I have
configured my ~/.gnupg/gpg-agent.conf file with:

--8<---------------cut here---------------start------------->8---
debug-level advanced
default-cache-ttl 14400
log-file /home/ucecesf/tmp/gpg-agent-log
max-cache-ttl 14400
pinentry-program /usr/bin/pinentry
--8<---------------cut here---------------end--------------->8---

and it does seem to be used (debugging is enabled and so is the log
file).  However, still not caching.

Any suggestions?

Thanks,
eric
