=head1 DESCRIPTION
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>.
=item B<-mac-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>.
=item B<-public-key-algorithms>
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<-engines>
+
+Display a list of loaded engines.
+
=item B<-disabled>
Display a list of disabled features, those that were compiled out
