=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.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.
|
|
|
|
=item B<-engine id>
|
|
|
|
Specifying an engine (by its unique B<id> string) will cause B<speed>
|
|
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<-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 algo>
|
|
|
|
Use the specified cipher or message digest algorithm via the EVP interface.
|
|
If B<algo> is an AEAD cipher, then you can pass <-aead> to benchmark a
|
|
TLS-like sequence. And if B<algo> is a multi-buffer capable cipher, e.g.
|
|
aes-128-cbc-hmac-sha1, then B<-mb> will time multi-buffer operation.
|
|
|
|
=item B<-hmac digest>
|
|
|
|
Time the HMAC algorithm using the specified message digest.
|
|
|
|
=item B<-cmac cipher>
|
|
|
|
Time the CMAC algorithm using the specified cipher e.g. B<speed -cmac aes128>.
|
|
|
|
=item B<-decrypt>
|
|
|
|
Time the decryption instead of encryption. Affects only the EVP testing.
|
|
|
|
=item B<-rand file...>
|
|
|
|
A file or 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>]
|
|
|
|
Writes random data to the specified I<file> upon exit.
|
|
This can be used with a subsequent B<-rand> flag.
|
|
|
|
=item B<-primes num>
|
|
|
|
Generate a B<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 num>
|
|
|
|
Run benchmarks for B<num> seconds.
|
|
|
|
=item B<-bytes num>
|
|
|
|
Run benchmarks on B<num>-byte buffers. Affects ciphers, digests and the CSPRNG.
|
|
|
|
=item B<[zero or more test algorithms]>
|
|
|
|
If any options are given, B<speed> tests those algorithms, otherwise a
|
|
pre-compiled grand selection is tested.
