# NAME

openssl-speed - test library performance

# SYNOPSIS

openssl speed [-help] [-config filename] [-elapsed] [-evp algo] [-hmac algo] [-cmac algo] [-mb] [-aead] [-kem-algorithms] [-signature-algorithms] [-multi num] [-async_jobs num] [-misalign num] [-decrypt] [-primes num] [-seconds num] [-bytes num] [-mr] [-mlock] [-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.

-config filename

  Specifies the configuration file to use. Optional; for a description of the default value, see "COMMAND SUMMARY" in openssl(1).

-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.

-kem-algorithms

  Benchmark KEM algorithms: key generation, encapsulation, decapsulation.

-signature-algorithms

  Benchmark signature algorithms: key generation, signature, verification.

-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. The limit on the size of the buffer is INT_MAX - 64 bytes, which for a 32-bit int would be 2147483583 bytes.

-mr

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

-mlock

  Lock memory into RAM for more deterministic measurements.

-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.

DSA512 was removed in OpenSSL 3.2.
