openssl-speed - test library performance
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 ...]
This command is used to test the performance of cryptographic algorithms.
Print out a usage message.
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.
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.
Run multiple operations in parallel.
Enable async mode and start specified number of jobs.
Misalign the buffers by the specified number of bytes.
Time the HMAC algorithm using the specified message digest.
Time the CMAC algorithm using the specified cipher e.g. openssl speed -cmac aes128.
Time the decryption instead of encryption. Affects only the EVP testing.
Enable multi-block mode on EVP-named cipher.
Benchmark EVP-named AEAD cipher in TLS-like sequence.
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.
Run benchmarks for num seconds.
Run benchmarks on num-byte buffers. Affects ciphers, digests and the CSPRNG.
Produce the summary in a mechanical, machine-readable, format.
See "Random State Options" in openssl(1) for details.
See "Engine Options" in openssl(1). This option is deprecated.
See "Provider Options" in openssl(1), provider(7), and property(7).
If any algorithm is given, then those algorithms are tested, otherwise a pre-compiled grand selection is tested.
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.
The -engine option was deprecated in OpenSSL 3.0.
