=head1 DESCRIPTION
This command is used to test the performance of cryptographic algorithms.
To see the list of supported algorithms, use the I<list --digest-commands>
or I<list --cipher-commands> command. The global CSPRNG is denoted by
-the I<rand> algorithm name.

to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default
for all available algorithms.

-=item B<-hmac digest>
+=item B<-hmac> I<digest>
Time the HMAC algorithm using the specified message digest.
-=item B<-cmac cipher>
+=item B<-cmac> I<cipher>
Time the CMAC algorithm using the specified cipher e.g. B<speed -cmac aes128>.
Time the decryption instead of encryption. Affects only the EVP testing.
-=item B<-rand file...>
+=item B<-rand> I<files>
-A file or files containing random data used to seed the random number

+The files containing random data used to seed the random number generator.
Multiple files can be specified separated by an OS-dependent character.
The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
all others.
-=item [B<-writerand file>]
+=item B<-writerand> I<file>
Writes random data to the specified I<file> upon exit.
This can be used with a subsequent B<-rand> flag.

If any options are given, B<speed> tests those algorithms, otherwise a
pre-compiled grand selection is tested.
