+ <para>
+ <command>apt-key</command> 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.
+ </para>
+ <para>
+ Use of <command>apt-key</command> is deprecated, except for the use of
+ <command>apt-key del</command> in maintainer scripts to remove existing
+ keys from the main keyring.
+ If such usage of <command>apt-key</command> is desired the additional
+ installation of the GNU Privacy Guard suite (packaged in
+ <package>gnupg</package>) is required.
+ </para>
+ <para>
+ apt-key(8) will last be available in Debian 11 and Ubuntu 22.04.
+ </para>
+</refsect1>
+
+<refsect1><title>Supported keyring files</title>
+<para>apt-key supports only the binary OpenPGP format (also known as "GPG key
+ public ring") in files with the "<literal>gpg</literal>" extension, not
+ the keybox database format introduced in newer &gpg; versions as default
+ for keyring files. Binary keyring files intended to be used with any apt
+ version should therefore always be created with <command>gpg --export</command>.
+</para>
+<para>Alternatively, if all systems which should be using the created keyring
+ have at least apt version >= 1.4 installed, you can use the ASCII armored
+ format with the "<literal>asc</literal>" extension instead which can be
+ created with <command>gpg --armor --export</command>.
+</para>

+ <varlistentry><term><option>add</option> <option>&synopsis-param-filename;</option> (deprecated)</term>
+ <listitem>
+ <para>
+ Add a new key to the list of trusted keys.
+ The key is read from the filename given with the parameter
+ &synopsis-param-filename; or if the filename is <literal>-</literal>
+ from standard input.
+ </para>
+ <para>
+ It is critical that keys added manually via <command>apt-key</command> are
+ verified to belong to the owner of the repositories they claim to be for
+ otherwise the &apt-secure; infrastructure is completely undermined.
+ </para>
+ <para>
+ <emphasis>Note</emphasis>: Instead of using this command a keyring
+ should be placed directly in the <filename>/etc/apt/trusted.gpg.d/</filename>
+ directory with a descriptive name and either "<literal>gpg</literal>" or
+ "<literal>asc</literal>" as file extension.

+ <para>
+ Pass advanced options to gpg. With <command>adv --recv-key</command> you
+ can e.g. download key from keyservers directly into the trusted set of
+ keys. Note that there are <emphasis>no</emphasis> checks performed, so it is

+ <varlistentry><term><option>update</option> (deprecated)</term>
+ <listitem>
+ <para>
+ 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 <literal>archive-keyring</literal> package of your
+ distribution, e.g. the &keyring-package; package in &keyring-distro;.
+ </para>
+ <para>
+ Note that a distribution does not need to and in fact should not use
+ this command any longer and instead ship keyring files in the
+ <filename>/etc/apt/trusted.gpg.d/</filename> directory directly as this
+ avoids a dependency on <package>gnupg</package> and it is easier to manage
+ keys by simply adding and removing files for maintainers and users alike.
+ </para>

+ </varlistentry>
+
+ <varlistentry><term><option>net-update</option> (deprecated)</term>
+ <listitem>
+ <para>
+
+ Perform an update working similarly to the <command>update</command> command above,
+ but get the archive keyring from a URI instead and validate it against a master key.
+
+ This requires an installed &wget; 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
+ <command>update</command> instead, but Ubuntu's APT does.

+ <listitem><para>With this option it is possible to specify a particular keyring

+ on the <filename>trusted.gpg</filename> file as well as on all parts in the

+ is the primary keyring which means that e.g. new keys are added to this one.
