NAMEopenssl−speed − test library performance
SYNOPSISopenssl 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 ...]
DESCRIPTIONThis 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 \*(C`openssl list \-digest\-algorithms\*(C'\fR or \f(CW\*(C`openssl list \-cipher\-algorithms\*(C'\fR 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. \*(C`openssl speed \-cmac aes128\*(C'\fR. −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.
BUGSThe algorithm can be selected only from a pre-compiled subset of things that the \*(C`openssl speed\*(C'\fR command knows about. To test any additional digest or cipher algorithm supported by OpenSSL use the \*(C`\-evp\*(C'\fR option. There is no way to test the speed of any additional public key algorithms supported by third party providers with the \*(C`openssl speed\*(C'\fR command.
HISTORYThe −engine option was deprecated in OpenSSL 3.0.
