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. 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.
-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.
