This command is used to test the performance of cryptographic
algorithms. To see the list of supported algorithms, use the list
--digest-commands or list --cipher-commands command. The global CSPRNG
is denoted by the rand algorithm name.
Print out a usage message.
Specifying an engine (by its unique id string) will cause speed to
attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the
default for all available algorithms.
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
Time the decryption instead of encryption. Affects only the EVP
A file or files containing random data used to seed the random
number generator. Multiple files can be specified separated by an
OS-dependent character. The separator is ; for MS-Windows, , for
OpenVMS, and : for all others.
Writes random data to the specified file upon exit. This can be
used with a subsequent -rand flag.
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
[zero or more test algorithms]
If any options are given, speed tests those algorithms, otherwise a
pre-compiled grand selection is tested.
