> 1) How can I set the time for retention of the Passphrase?
This depends on what version of GnuPG you're using. The mechanism
changed between GnuPG 1.4 and 2.0. Look for a configuration file called
"gpg-agent.conf" (normally found in ~/.gnupg; dunno where it would be
stored on iOS). Open it up with your favorite text editor and look for
That's the duration, in seconds, your passphrase will be retained. 3600
seconds is one hour, and 86400 seconds is one day.
> 2) What is the best way to automatically send my Public Key to message
Don't. Public keys are big and a little obnoxious. Send your public
certificate to a keyserver. In your email signature, you can say
something like "OpenPGP Certificate ID: 1DCBDC01B44427C7". Anyone can
then retrieve your public certificate by typing something like:
$ gpg --keyserver pool.sks-keyservers.net --recv-key 1DCBDC01B44427C7
... and presto, they get it and import it into GnuPG, all in one statement.
