NAME
       apt-key - APT key management utility

SYNOPSIS
       apt-key [--keyring filename] [command] [arguments...]

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
	   filename, or standard input if filename is -.

       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 keyring of Debian archive keys
	   and removes from the keyring the archive keys which are no longer
	   valid.

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 specific 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, through trusted.gpg is the primary keyring
	   which means that e.g. new keys are added to this one.
