2 Invoking GPG-AGENT

gpg-agent is a daemon to manage secret (private) keys independently from any protocol. It is used as a backend for gpg and gpgsm as well as for a couple of other utilities.

The agent is usualy started on demand by gpg, gpgsm, gpgconf or gpg-connect-agent. Thus there is no reason to start it manually. In case you want to use the included Secure Shell Agent you may start the agent using:

     gpg-connect-agent /bye

You should always add the following lines to your .bashrc or whatever initialization file is used for all shell invocations:

     GPG_TTY=$(tty)
     export GPG_TTY

It is important that this environment variable always reflects the output of the tty command. For W32 systems this option is not required.

Please make sure that a proper pinentry program has been installed under the default filename (which is system dependant) or use the option pinentry-program to specify the full name of that program. It is often useful to install a symbolic link from the actual used pinentry (e.g. /usr/bin/pinentry-gtk) to the expected one (e.g. /usr/bin/pinentry).
