.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This command is used to test the performance of cryptographic algorithms.
To see the list of supported algorithms, use \f(CW\*(C`openssl list \-digest\-commands\*(C'\fR
or \f(CW\*(C`openssl list \-cipher\-commands\*(C'\fR command. The global \s-1CSPRNG\s0 is denoted by
the \fBrand\fR algorithm name.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-help\fR" 4
.IX Item "-help"
Print out a usage message.
.IP "\fB\-elapsed\fR" 4
.IX Item "-elapsed"
When calculating operations\- or bytes-per-second, use wall-clock time
instead of \s-1CPU\s0 user time as divisor. It can be useful when testing speed
of hardware engines.
.IP "\fB\-evp\fR \fIalgo\fR" 4
.IX Item "-evp algo"
Use the specified cipher or message digest algorithm via the \s-1EVP\s0 interface.
If \fIalgo\fR is an \s-1AEAD\s0 cipher, then you can pass \fB\-aead\fR to benchmark a
TLS-like sequence. And if \fIalgo\fR is a multi-buffer capable cipher, e.g.
aes\-128\-cbc\-hmac\-sha1, then \fB\-mb\fR will time multi-buffer operation.
.IP "\fB\-multi\fR \fInum\fR" 4
.IX Item "-multi num"
Run multiple operations in parallel.
.IP "\fB\-async_jobs\fR \fInum\fR" 4
.IX Item "-async_jobs num"
Enable async mode and start specified number of jobs.
.IP "\fB\-misalign\fR \fInum\fR" 4
.IX Item "-misalign num"
Misalign the buffers by the specified number of bytes.
.IP "\fB\-hmac\fR \fIdigest\fR" 4
.IX Item "-hmac digest"
Time the \s-1HMAC\s0 algorithm using the specified message digest.
.IP "\fB\-cmac\fR \fIcipher\fR" 4
.IX Item "-cmac cipher"
Time the \s-1CMAC\s0 algorithm using the specified cipher e.g.
\&\f(CW\*(C`openssl speed \-cmac aes128\*(C'\fR.
.IP "\fB\-decrypt\fR" 4
.IX Item "-decrypt"
Time the decryption instead of encryption. Affects only the \s-1EVP\s0 testing.
.IP "\fB\-primes\fR \fInum\fR" 4
.IX Item "-primes num"
Generate a \fInum\fR\-prime \s-1RSA\s0 key and use it to run the benchmarks. This option
is only effective if \s-1RSA\s0 algorithm is specified to test.
.IP "\fB\-seconds\fR \fInum\fR" 4
.IX Item "-seconds num"
Run benchmarks for \fInum\fR seconds.
.IP "\fB\-bytes\fR \fInum\fR" 4
.IX Item "-bytes num"
Run benchmarks on \fInum\fR\-byte buffers. Affects ciphers, digests and the \s-1CSPRNG\s0.
.IP "\fB\-mr\fR" 4
.IX Item "-mr"
Produce the summary in a mechanical, machine-readable, format.
.IP "\fB\-rand\fR \fIfiles\fR, \fB\-writerand\fR \fIfile\fR" 4
.IX Item "-rand files, -writerand file"
See \*(L"Random State Options\*(R" in \fIopenssl\fR\|(1) for details.
.IP "\fB\-engine\fR \fIid\fR" 4
.IX Item "-engine id"
See \*(L"Engine Options\*(R" in \fIopenssl\fR\|(1).
.IP "\fIalgorithm\fR ..." 4
.IX Item "algorithm ..."
If any \fIalgorithm\fR is given, then those algorithms are tested, otherwise a
pre-compiled grand selection is tested.
