[I<file> ...]
Print out the digest in two digit groups separated by colons, only relevant if
the B<-hex> option is given as well.
-=item B<-d>
+=item B<-d>, B<-debug>
Print out BIO debugging information.
The engine is not used for digests unless the B<-engine_impl> option is
used or it is configured to do so, see L<config(5)/Engine Configuration Module>.
-=item B<-engine_impl>
+=item B<-engine_impl> I<id>
When used with the B<-engine> option, it specifies to also use
engine I<id> for digest operations.
