Name
----
pacman-key - manage pacman's list of trusted keys


Synopsis
--------
'pacman-key' [options]


Description
-----------
'pacman-key' is a wrapper script for GnuPG used to manage pacman's keyring, which
is the collection of PGP keys used to check signed packages and databases. It
provides the ability to import and export keys, fetch keys from keyservers and
update the key trust database.

More complex keyring management can be achieved using GnuPG directly combined with
the '\--homedir' option pointing at the pacman keyring (located in
+{sysconfdir}/pacman.d/gnupg+ by default).


Options
-------
*-a, \--add* [file(s)]::
	Add the key(s) contained in the specified file or files to pacman's
	keyring. If a key already exists, update it.

*\--config* <file>::
	Use an alternate config file instead of the +{sysconfdir}/pacman.conf+
	default.

*-d, \--delete* <keyid(s)>::
	Remove the key(s) identified by the specified keyid(s) from pacman's
	keyring.

*-e, \--export* [keyid(s)]::
	Export key(s) identified by the specified keyid(s) to 'stdout'. If no keyid
	is specified, all keys will be exported.

*\--edit-key* <keyid(s)>::
	Present a menu for key management task on the specified keyid(s). Useful
	for adjusting a keys trust level.

*-f, \--finger* [keyid(s)]::
	List a fingerprint for each specified keyid, or for all known keys if no
	keyids are specified.

*\--gpgdir* <dir>::
	Set an alternate home directory for GnuPG. If unspecified, the value is
	read from +{sysconfdir}/pacman.conf+.

*-h, \--help*::
	Output syntax and command line options.

*\--import* <dir(s)>::
	Imports keys from `pubring.gpg` into the public keyring from the specified
	directories.

*\--import-trustdb* <dir(s)> ::
	Imports ownertrust values from `trustdb.gpg` into the shared trust database
	from the specified directories.

*\--init*::
	Ensure the keyring is properly initialized and has the required access
	permissions.

*\--keyserver* <keyserver>::
	Use the specified keyserver if the operation requires one. This will take
	precedence over any keyserver option specified in a `gpg.conf`
	configuration file. Running '\--init' with this option will set the default
	keyserver if one was not already configured.

*-l, \--list-keys* [keyid(s)]::
	Lists all or specified keys from the public keyring.

*\--list-sigs* [keyid(s)]::
	Same as '\--list-keys', but the signatures are listed too.

*\--lsign-key* <keyid>::
	Locally sign the given key. This is primarily used to root the web of trust
	in the local private key generated by '\--init'.

*-r, \--recv-keys* <keyid(s)>::
	Equivalent to '\--recv-keys' in GnuPG.

*\--refresh-keys* [keyid(s)]::
	Equivalent to '\--refresh-keys' in GnuPG.

*\--populate* [keyring(s)]::
	Reload the default keys from the (optionally provided) keyrings in
	+{pkgdatadir}/keyrings+. For more information, see
	<<SC,Providing a Keyring for Import>> below.

*-u, \--updatedb*::
	Equivalent to '\--check-trustdb' in GnuPG.

*-v, \--verify* <signature>::
	Verify the given signature file.

*-V, \--version*::
	Displays the program version.


Providing a Keyring for Import
------------------------------
A distribution or other repository provided may want to provide a set of
PGP keys used in the signing of its packages and repository databases that can
be readily imported into the pacman keyring. This is achieved by providing a
PGP keyring file `foo.gpg` that contains the keys for the foo keyring in the
directory +{pkgdatadir}/keyrings+.

Optionally, the file `foo-trusted` can be provided containing a list of trusted
key IDs for that keyring. This is a file in a format compatible with 'gpg
\--export-ownertrust' output. This file will inform the user which keys a user
needs to verify and sign to build a local web of trust, in addition to
assigning provided owner trust values.

Also optionally, the file `foo-revoked` can be provided containing a list of
revoked key IDs for that keyring. Revoked is defined as "no longer valid for
any signing", so should be used with prudence. A key being marked as revoked
will be disabled in the keyring and no longer treated as valid, so this always
takes priority over it's trusted state in any other keyring.

All files are required to be signed (detached) by a trusted PGP key that the
user must manually import to the pacman keyring. This prevents a potentially
malicious repository adding keys to the pacman keyring without the users
knowledge.
