=head1 DESCRIPTION
This command is used to test the performance of cryptographic algorithms.
To see the list of supported algorithms, use C<openssl list -digest-commands>
or C<openssl list -cipher-commands> command. The global CSPRNG is denoted by
the B<rand> algorithm name.
=head1 OPTIONS
=over 4
=item B<-help>
Print out a usage message.
=item B<-elapsed>
When calculating operations- or bytes-per-second, use wall-clock time
instead of CPU user time as divisor. It can be useful when testing speed
of hardware engines.
=item B<-evp> I<algo>
Use the specified cipher or message digest algorithm via the EVP interface.
If I<algo> is an AEAD cipher, then you can pass B<-aead> to benchmark a
TLS-like sequence. And if I<algo> is a multi-buffer capable cipher, e.g.
aes-128-cbc-hmac-sha1, then B<-mb> will time multi-buffer operation.
=item B<-multi> I<num>
Run multiple operations in parallel.
=item B<-async_jobs> I<num>
Enable async mode and start specified number of jobs.
=item B<-misalign> I<num>
Misalign the buffers by the specified number of bytes.
=item B<-hmac> I<digest>
Time the HMAC algorithm using the specified message digest.
=item B<-cmac> I<cipher>
Time the CMAC algorithm using the specified cipher e.g.
C<openssl speed -cmac aes128>.
=item B<-decrypt>
Time the decryption instead of encryption. Affects only the EVP testing.
=item B<-primes> I<num>
Generate a I<num>-prime RSA key and use it to run the benchmarks. This option
is only effective if RSA algorithm is specified to test.
=item B<-seconds> I<num>
Run benchmarks for I<num> seconds.
=item B<-bytes> I<num>
Run benchmarks on I<num>-byte buffers. Affects ciphers, digests and the CSPRNG.
=item B<-mr>
Produce the summary in a mechanical, machine-readable, format.
{- $OpenSSL::safe::opt_r_item -}
{- $OpenSSL::safe::opt_engine_item -}
{- $OpenSSL::safe::opt_provider_item -}
=item I<algorithm> ...
If any I<algorithm> is given, then those algorithms are tested, otherwise a
pre-compiled grand selection is tested.
