       apt-key - APT key management utility

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

       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.

       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.

	   Output all trusted keys to standard output.

	   List trusted keys.

	   List fingerprints of trusted keys.

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

	   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	   the archive keys which are no longer valid.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 debian-archive-keyring package
	   in Debian.

	   Work similar to the update command above, but get the archive keyring from an 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 and relies on update instead,
	   but Ubuntu's APT does.

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

       --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.

	   Keyring of local trusted keys, new keys will be added here. Configuration Item:

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

	   Local trust database of archive keys.

	   Keyring of Debian archive trusted keys.

	   Keyring of Debian archive removed trusted keys.

       apt-get(8), apt-secure(8)
