The @code{(gnu home services gnupg)} modules provides services that help

you set up the GNU Privacy Guard, also known as GnuPG or GPG, in your

home environment.
|

@cindex gpg-agent, Home service

@cindex SSH agent, with gpg-agent

program that is responsible for managing OpenPGP private keys and,

||||
optionally, OpenSSH (secure shell) private keys (@pxref{Invoking
|
||||

|

|

As an example, here is how you would configure @code{gpg-agent} with SSH

support such that it uses the Emacs-based Pinentry interface when
