=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<-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
  foo => bar
then B<foo> is an alias for the official algorithm name, B<bar>.

=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
  foo => bar
then B<foo> is an alias for the official algorithm name, B<bar>.

=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: this also includes public key methods
without an associated ASN.1 method, for example, KDF algorithms.

=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>.
