You know your working scenarios, we on this mailing list don't
(at least as long as you don't give more details). So it's only
you who can evaluate these and who must decide finally. As
always, the evaluation of the scenarios comes first, the
selection of the means (software) to face them comes afterwards.
I think you should invest some time to go through the man pages
of all the commands you intend to use. For example gpg-agent(1):
Set the time a cache entry is valid to n seconds. The
default is 600 seconds.
Set the maximum time a cache entry is valid to n seconds.
After this time a cache entry will be expired even if it
has been accessed recently. The default is 2 hours (7200
If unsure, keep using the defaults.
Do you want to encrypt your mail? Then join CAcert and get your SSL
certificate from https://www.CAcert.org. If you have any questions,
don't hesitate to ask.
