=head1 DESCRIPTION
This command is used to generate list of algorithms or disabled
features.
=head1 OPTIONS
=over 4
=item B<-help>
Display a usage message.
=item B<-verbose>
Displays extra information.
The options below where verbosity applies say a bit more about what that means.
=item B<-select> I<name>
Only list algorithms that match this name.
=item B<-1>
List the commands, digest-commands, or cipher-commands in a single column.
If used, this option must be given first.
=item B<-commands>
Display a list of standard commands.
=item B<-standard-commands>
List of standard commands.
=item B<-digest-commands>
This option is deprecated. Use B<digest-algorithms> instead.
Display a list of message digest commands, which are typically used
as input to the L<openssl-dgst(1)> or L<openssl-speed(1)> commands.
=item B<-cipher-commands>
This option is deprecated. Use B<cipher-algorithms> instead.
Display a list of cipher commands, which are typically used as input
to the L<openssl-enc(1)> or L<openssl-speed(1)> commands.
=item B<-digest-algorithms>, B<-kdf-algorithms>, B<-mac-algorithms>,
B<-cipher-algorithms>
Display a list of cipher, digest, kdf and mac algorithms.
See L</Display of algorithm names> for a description of how names are
displayed.
In verbose mode, the algorithms provided by a provider will get additional
information on what parameters each implementation supports.
=item B<-random-instances>
List the primary, public and private random number generator details.
=item B<-random-generators>
Display a list of random number generators.
See L</Display of algorithm names> for a description of how names are
displayed.
=item B<-encoders>
Display a list of encoders.
See L</Display of algorithm names> for a description of how names are
displayed.
In verbose mode, the algorithms provided by a provider will get additional
information on what parameters each implementation supports.
=item B<-decoders>
Display a list of decoders.
See L</Display of algorithm names> for a description of how names are
displayed.
In verbose mode, the algorithms provided by a provider will get additional
information on what parameters each implementation supports.
=item B<-public-key-algorithms>
Display a list of public key algorithms, with each algorithm as
a block of multiple lines, all but the first are indented.
The options B<key-exchange-algorithms>, B<kem-algorithms>,
B<signature-algorithms>, and B<asymcipher-algorithms> will display similar info.
=item B<-public-key-methods>
Display a list of public key methods.
=item B<-key-managers>
Display a list of key managers.
=item B<-key-exchange-algorithms>
Display a list of key exchange algorithms.
=item B<-kem-algorithms>
Display a list of key encapsulation algorithms.
=item B<-signature-algorithms>
Display a list of signature algorithms.
=item B<-asymcipher-algorithms>
Display a list of asymmetric cipher algorithms.
=item B<-providers>
Display a list of all loaded providers with their names, version and status.
In verbose mode, the full version and all provider parameters will additionally
be displayed.
=item B<-engines>
This option is deprecated.
Display a list of loaded engines.
=item B<-disabled>
Display a list of disabled features, those that were compiled out
of the installation.
=item B<-missing-help>
List missing detailed help strings.
=item B<-objects>
Display a list of built in objects, i.e. OIDs with names. They're listed in the
format described in L<config(5)/ASN1 Object Configuration Module>.
=item B<-options> I<command>
Output a two-column list of the options accepted by the specified I<command>.
The first is the option name, and the second is a one-character indication
of what type of parameter it takes, if any.
This is an internal option, used for checking that the documentation
is complete.

=head2 Display of algorithm names
Algorithm names may be displayed in one of two manners:
=over 4
=item Legacy implementations
Legacy implementations will simply display the main name of the
algorithm on a line of its own, or in the form C<<foo > bar>> to show
that C<foo> is an alias for the main name, C<bar>
=item Provided implementations
Implementations from a provider are displayed like this if the
implementation is labeled with a single name:
foo @ bar
or like this if it's labeled with multiple names:
{ foo1, foo2 } @bar
In both cases, C<bar> is the name of the provider.
=back
=head1 HISTORY
The B<-engines>, B<-digest-commands>, and B<-cipher-commands> options
were deprecated in OpenSSL 3.0.
