Optional; for a description of the default value, see "COMMAND SUMMARY" in \fBopenssl\fR\|(1). .IP \fB\-elapsed\fR 4 .IX Item "-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. .IP "\fB\-evp\fR \fIalgo\fR" 4 .IX Item "-evp algo" Use the specified cipher or message digest algorithm via the EVP interface. If \fIalgo\fR is an AEAD 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. .Sp To see the algorithms supported with this option, use \&\f(CW\*(C`openssl list \-digest\-algorithms\*(C'\fR or \f(CW\*(C`openssl list \-cipher\-algorithms\*(C'\fR command. .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 HMAC algorithm using the specified message digest. .IP "\fB\-cmac\fR \fIcipher\fR" 4 .IX Item "-cmac cipher" Time the CMAC 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 EVP testing. .IP \fB\-mb\fR 4 .IX Item "-mb" Enable multi-block mode on EVP-named cipher. .IP \fB\-aead\fR 4 .IX Item "-aead" Benchmark EVP-named AEAD cipher in TLS-like sequence. .IP "\fB\-primes\fR \fInum\fR" 4 .IX Item "-primes num" Generate a \fInum\fR\-prime RSA key and use it to run the benchmarks. This option is only effective if RSA 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 CSPRNG. The limit on the size of the buffer is INT_MAX \- 64 bytes, which for a 32\-bit int would be 2147483583 bytes. .IP \fB\-mr\fR 4 .IX Item "-mr" Produce the summary in a mechanical, machine-readable, format. .IP \fB\-mlock\fR 4 .IX Item "-mlock" Lock memory into RAM for more deterministic measurements. .IP "\fB\-rand\fR \fIfiles\fR, \fB\-writerand\fR \fIfile\fR" 4 .IX Item "-rand files, -writerand file" See "Random State Options" in \fBopenssl\fR\|(1) for details. .IP "\fB\-engine\fR \fIid\fR" 4 .IX Item "-engine id" See "Engine Options" in \fBopenssl\fR\|(1). This option is deprecated. .IP "\fB\-provider\fR \fIname\fR" 4 .IX Item "-provider name" .PD 0 .IP "\fB\-provider\-path\fR \fIpath\fR" 4 .IX Item "-provider-path path" .IP "\fB\-propquery\fR \fIpropq\fR" 4 .IX Item "-propquery propq" .PD See "Provider Options" in \fBopenssl\fR\|(1), \fBprovider\fR\|(7), and \fBproperty\fR\|(7). .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. .SH BUGS .IX Header "BUGS" The \fIalgorithm\fR can be selected only from a pre-compiled subset of things that the \f(CW\*(C`openssl speed\*(C'\fR command knows about. To test any additional digest or cipher algorithm supported by OpenSSL use the \f(CW\*(C`\-evp\*(C'\fR option. .PP There is no way to test the speed of any additional public key algorithms supported by third party providers with the \f(CW\*(C`openssl speed\*(C'\fR command. .SH HISTORY .IX Header "HISTORY" The \fB\-engine\fR option was deprecated in OpenSSL 3.0. .SH COPYRIGHT .IX Header "COPYRIGHT" Copyright 2000\-2022 The OpenSSL Project Authors.
