APT-KEY(8)			      APT			    APT-KEY(8)

NAME
       apt-key - APT key management utility

SYNOPSIS
       apt-key [--keyring filename] {add filename | del keyid | export keyid |
	       exportall | list | finger | adv | update | net-update |
	       {-v | --version} | {-h | --help}}

DESCRIPTION
       apt-key is used to manage the list of keys used by apt to authenticate
       packages. Packages which have been authenticated using these keys will
       be considered trusted.

COMMANDS
       add filename
	   Add a new key to the list of trusted keys. The key is read from the
	   filename given with the parameter filename or if the filename is -
	   from standard input.

       del keyid
	   Remove a key from the list of trusted keys.

       export keyid
	   Output the key keyid to standard output.

       exportall
	   Output all trusted keys to standard output.

       list
	   List trusted keys.

       finger
	   List fingerprints of trusted keys.

       adv
	   Pass advanced options to gpg. With adv --recv-key you can download
	   the public key.

       update
	   Update the local keyring with the archive keyring and remove from
	   the local keyring the archive keys which are no longer valid. The
	   archive keyring is shipped in the archive-keyring package of your
	   distribution, e.g. the ubuntu-keyring package in Ubuntu.

       net-update
	   Perform an update working similarly to the update command above,
	   but get the archive keyring from a URI instead and validate it
	   against a master key. This requires an installed wget(1) and an APT
	   build configured to have a server to fetch from and a master
	   keyring to validate. APT in Debian does not support this command,
	   relying on update instead, but Ubuntu's APT does.

OPTIONS
       Note that options need to be defined before the commands described in
       the previous section.

       --keyring filename
	   With this option it is possible to specify a particular keyring
	   file the command should operate on. The default is that a command
	   is executed on the trusted.gpg file as well as on all parts in the
	   trusted.gpg.d directory, though trusted.gpg is the primary keyring
	   which means that e.g. new keys are added to this one.

FILES
       /etc/apt/trusted.gpg
	   Keyring of local trusted keys, new keys will be added here.
	   Configuration Item: Dir::Etc::Trusted.

       /etc/apt/trusted.gpg.d/
	   File fragments for the trusted keys, additional keyrings can be
	   stored here (by other packages or the administrator). Configuration
	   Item Dir::Etc::TrustedParts.

       /etc/apt/trustdb.gpg
	   Local trust database of archive keys.

       /usr/share/keyrings/ubuntu-archive-keyring.gpg
	   Keyring of Ubuntu archive trusted keys.

       /usr/share/keyrings/ubuntu-archive-removed-keys.gpg
	   Keyring of Ubuntu archive removed trusted keys.
