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.
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 multi-buffer operation.
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.
