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] [-testmode] [-rand files]
     [-writerand file] [-provider name] [-provider-path path] [-provparam
     [name:]key=value] [-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.

     -evp algo
	 Use the specified cipher or message digest algorithm via the EVP inter-
	 face.	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 test-
	 ing.

     -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, verifica-
	 tion.

     -primes num
	 Generate a num-prime RSA key and use it to run the benchmarks. This op-
	 tion 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.

     -testmode
	 Runs the speed command in testmode. Runs only 1 iteration of each algo-
	 rithm test regardless of any -seconds value. In the event that any op-
	 eration fails then the speed command will return with a failure result.

     -rand files, -writerand file
	 See "Random State Options" in openssl(1) for details.

     -provider name
     -provider-path path
     -provparam [name:]key=value
     -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.

     The -testmode option was added in OpenSSL 3.4.

     The -engine option was removed in OpenSSL 4.0.
