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 a new key to the list of trusted keys. The key is read from
filename, or standard input if filename is -.
Remove a key from the list of trusted keys.
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the local keyring the archive keys which are no longer valid.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 section.
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: Dir::Etc::Trusted.
File fragments for the trusted keys, additional keyrings can be
stored here (by other packages or the administrator). Configuration
Local trust database of archive keys.
Keyring of Debian archive trusted keys.
Keyring of Debian archive removed trusted keys.
