openssl-speed - test library performance

<h1 id="SYNOPSIS">SYNOPSIS</h1>

openssl speed [-help] [-elapsed] [-evp algo] [-hmac algo] [-cmac algo] [-mb] [-aead] [-multi num] [-async_jobs num] [-misalign num] [-decrypt] [-primes num] [-seconds num] [-bytes num] [-mr] [-rand files] [-writerand file] [-engine id] [-provider name] [-provider-path path] [-propquery propq] [algorithm ...]

<h1 id="DESCRIPTION">DESCRIPTION</h1>

This command is used to test the performance of cryptographic algorithms.

<h1 id="OPTIONS">OPTIONS</h1>

<dl>

Print out a usage message.

</dd>
<dt id="elapsed">-elapsed</dt>
<dd>

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.

</dd>
<dt id="evp-algo">-evp algo</dt>
<dd>

Use the specified cipher or message digest algorithm via the EVP interface. If algo is an AEAD cipher, then you can pass -aead to benchmark a TLS-like sequence. And if algo is a multi-buffer capable cipher, e.g. aes-128-cbc-hmac-sha1, then -mb will time multi-buffer operation.

To see the algorithms supported with this option, use <code>openssl list -digest-algorithms</code> or <code>openssl list -cipher-algorithms</code> command.

</dd>
<dt id="multi-num">-multi num</dt>
<dd>

Run multiple operations in parallel.

</dd>
<dt id="async_jobs-num">-async_jobs num</dt>
<dd>

Enable async mode and start specified number of jobs.

</dd>
<dt id="misalign-num">-misalign num</dt>
<dd>

Misalign the buffers by the specified number of bytes.

</dd>
<dt id="hmac-digest">-hmac digest</dt>
<dd>

Time the HMAC algorithm using the specified message digest.

</dd>
<dt id="cmac-cipher">-cmac cipher</dt>
<dd>

Time the CMAC algorithm using the specified cipher e.g. <code>openssl speed -cmac aes128</code>.

</dd>
<dt id="decrypt">-decrypt</dt>
<dd>

Time the decryption instead of encryption. Affects only the EVP testing.

</dd>
<dt id="mb">-mb</dt>
<dd>

Enable multi-block mode on EVP-named cipher.

</dd>
<dt id="aead">-aead</dt>
<dd>

Benchmark EVP-named AEAD cipher in TLS-like sequence.

</dd>
<dt id="primes-num">-primes num</dt>
<dd>

Generate a num-prime RSA key and use it to run the benchmarks. This option is only effective if RSA algorithm is specified to test.

</dd>
<dt id="seconds-num">-seconds num</dt>
<dd>

Run benchmarks for num seconds.

</dd>
<dt id="bytes-num">-bytes num</dt>
<dd>

Run benchmarks on num-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.

</dd>
<dt id="mr">-mr</dt>
<dd>

Produce the summary in a mechanical, machine-readable, format.

</dd>
<dt id="rand-files--writerand-file">-rand files, -writerand file</dt>
<dd>

See <a href="../man1/openssl.html">&quot;Random State Options&quot; in openssl(1)</a> for details.

</dd>
<dt id="engine-id">-engine id</dt>
<dd>

See <a href="../man1/openssl.html">&quot;Engine Options&quot; in openssl(1)</a>. This option is deprecated.

</dd>
<dt id="provider-name">-provider name</dt>
<dd>

</dd>
<dt id="provider-path-path">-provider-path path</dt>
<dd>

</dd>
<dt id="propquery-propq">-propquery propq</dt>
<dd>

See <a href="../man1/openssl.html">&quot;Provider Options&quot; in openssl(1)</a>, <a href="../man7/provider.html">provider(7)</a>, and <a href="../man7/property.html">property(7)</a>.

</dd>
<dt id="algorithm">algorithm ...</dt>
<dd>

If any algorithm is given, then those algorithms are tested, otherwise a pre-compiled grand selection is tested.

</dd>
</dl>

The algorithm can be selected only from a pre-compiled subset of things that the <code>openssl speed</code> command knows about. To test any additional digest or cipher algorithm supported by OpenSSL use the <code>-evp</code> option.

There is no way to test the speed of any additional public key algorithms supported by third party providers with the <code>openssl speed</code> command.

<h1 id="HISTORY">HISTORY</h1>

The -engine option was deprecated in OpenSSL 3.0.
