+# gpgconf.conf - configuration for gpgconf
+#----------------------------------------------------------------------
+# This file is read by gpgconf(1) to setup defaults for all or
+# specified users and groups.  It may be used to change the hardwired
+# defaults in gpgconf and to enforce certain values for the various
+# GnuPG related configuration files.
+#
+# NOTE: This is a legacy mechanism.  The modern way is to use global
+#       configuration files like /etc/gnupg/gpg.conf which are more
+#       flexible and better integrated into the configuration system.
+#
+# Empty lines and comment lines, indicated by a hash mark as first non
+# white space character, are ignored.  The line is separated by white
+# space into fields. The first field is used to match the user or
+# group and must start at the first column, the file is processed
+# sequential until a matching rule is found.  A rule may contain
+# several lines; continuation lines are indicated by a indenting them.
+#
+# Syntax of a line:
+# <key>|WS  <component> <option> ["["<flag>"]"] [<value>]
+#
+# Examples for the <key> field:
+#   foo         - Matches the user "foo".
+#   foo:        - Matches the user "foo".
+#   foo:staff   - Matches the user "foo" or the group "staff".
+#   :staff      - Matches the group "staff".
+#   *           - Matches any user.
+# All other variants are not defined and reserved for future use.
+#
+# <component> and <option> are as specified by gpgconf.
+# <flag> may be one of:
+#   default     - Delete the option so that the default is used.
+#   no-change   - Mark the field as non changeable by gpgconf.
+#   change      - Mark the field as changeable by gpgconf.
+#
+# Example file:
+#==========
+# :staff  gpg-agent min-passphrase-len 6 [change]
+#
+# *       gpg-agent min-passphrase-len [no-change] 8
+#         gpg-agent min-passphrase-nonalpha [no-change] 1
+#         gpg-agent max-passphrase-days [no-change] 700
+#         gpg-agent enable-passphrase-history [no-change]
+#         gpg-agent enforce-passphrase-constraints [default]
+#         gpg-agent enforce-passphrase-constraints [no-change]
+#         gpg-agent max-cache-ttl [no-change] 10800
+#         gpg-agent max-cache-ttl-ssh [no-change] 10800
+#         gpgsm     enable-ocsp
+#         gpg       compliance [no-change]
+#         gpgsm     compliance [no-change]
+#===========
+# All users in the group "staff" are allowed to change the value for
+# --allow-mark-trusted; gpgconf's default is not to allow a change
+# through its interface.  When "gpgconf --apply-defaults" is used,
+# "allow-mark-trusted" will get enabled and "min-passphrase-len" set
+# to 6.  All other users are not allowed to change
+# "min-passphrase-len" and "allow-mark-trusted".  When "gpgconf
+# --apply-defaults" is used for them, "min-passphrase-len" is set to
+# 8, "allow-mark-trusted" deleted from the config file and
+# "enable-ocsp" is put into the config file of gpgsm.  The latter may
+# be changed by any user.

+Socket-activated dirmngr and gpg-agent with systemd
+===================================================
+
+When used on a GNU/Linux system supervised by systemd, you can ensure
+that the GnuPG daemons dirmngr and gpg-agent are launched
+automatically the first time they're needed, and shut down cleanly at
+session logout.  This is done by enabling user services via
+socket-activation.
+
+System distributors
+-------------------
+
+The *.service and *.socket files (from this directory) should be
+placed in /usr/lib/systemd/user/ alongside other user-session services
+and sockets.
+
+To enable socket-activated dirmngr for all accounts on the system,
+use:
+
+    systemctl --user --global enable dirmngr.socket
+
+To enable socket-activated gpg-agent for all accounts on the system,
+use:
+
+    systemctl --user --global enable gpg-agent.socket
+
+Additionally, you can enable socket-activated gpg-agent ssh-agent
+emulation for all accounts on the system with:
+
+    systemctl --user --global enable gpg-agent-ssh.socket
+
+You can also enable restricted ("--extra-socket"-style) gpg-agent
+sockets for all accounts on the system with:
+
+    systemctl --user --global enable gpg-agent-extra.socket
+
+Individual users
+----------------
+
+A user on a system with systemd where this has not been installed
+system-wide can place these files in ~/.config/systemd/user/ to make
+them available.
+
+If a given service isn't installed system-wide, or if it's installed
+system-wide but not globally enabled, individual users will still need
+to enable them.  For example, to enable socket-activated dirmngr for
+all future sessions:
+
+    systemctl --user enable dirmngr.socket
+
+To enable socket-activated gpg-agent with ssh support, do:
+
+    systemctl --user enable gpg-agent.socket gpg-agent-ssh.socket
+
+These changes won't take effect until your next login after you've
+fully logged out (be sure to terminate any running daemons before
+logging out).
+
+If you'd rather try a socket-activated GnuPG daemon in an
+already-running session without logging out (with or without enabling
+it for all future sessions), kill any existing daemon and start the
+user socket directly.  For example, to set up socket-activated dirmgnr
+in the current session:
+
+    gpgconf --kill dirmngr
+    systemctl --user start dirmngr.socket
