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           and removes from the keyring the archive keys which are no longer
           valid.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

       /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
