=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<-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<-digest-commands>

Display a list of message digest commands, which are typically used
as input to the L<dgst(1)> or L<speed(1)> commands.

=item B<-digest-algorithms>

Display a list of message digest algorithms.
If a line is of the form C<foo =E<gt> bar> then B<foo> is an alias for the
official algorithm name, B<bar>.
If a line is of the form C<foo @ bar>, then B<foo> is provided by the provider
B<bar>.

In verbose mode, the algorithms provided by a provider will get additional
information on what parameters each implementation supports.

=item B<-kdf-algorithms>

Display a list of key derivation function algorithms.

=item B<-mac-algorithms>

Display a list of message authentication code algorithms.

=item B<-cipher-commands>

Display a list of cipher commands, which are typically used as input
to the L<dgst(1)> or L<speed(1)> commands.

=item B<-cipher-algorithms>

Display a list of cipher algorithms.
If a line is of the form C<foo =E<gt> bar> then B<foo> is an alias for the
official algorithm name, B<bar>.
If a line is of the form C<foo @ bar>, then B<foo> is provided by the provider
B<bar>.

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.

=item B<-public-key-methods>

Display a list of public key method OIDs.

=item B<-engines>

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<-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>.
