NAME

openssl-speed - test library performance

SYNOPSIS

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 ...]

DESCRIPTION

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

OPTIONS

-help

Print out a usage message.

-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.

-evp algo

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 openssl list -digest-algorithms or openssl list -cipher-algorithms command.

-multi num

Run multiple operations in parallel.

-async_jobs num

Enable async mode and start specified number of jobs.

-misalign num

Misalign the buffers by the specified number of bytes.

-hmac digest

Time the HMAC algorithm using the specified message digest.

-cmac cipher

Time the CMAC algorithm using the specified cipher e.g. openssl speed -cmac aes128.

-decrypt

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

-mb

Enable multi-block mode on EVP-named cipher.

-aead

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

-primes num

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.

-seconds num

Run benchmarks for num seconds.

-bytes num

Run benchmarks on num-byte buffers. Affects ciphers, digests and the CSPRNG.

-mr

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

-rand files, -writerand file

See "Random State Options" in openssl(1) for details.

-engine id

See "Engine Options" in openssl(1). This option is deprecated.

-provider name
-provider-path path
-propquery propq

See "Provider Options" in openssl(1), provider(7), and property(7).

algorithm ...

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

BUGS

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

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

HISTORY

The -engine option was deprecated in OpenSSL 3.0.
