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