openssl speed [-help] [-engine id] [-elapsed] [-evp algo] [-decrypt]
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.
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.
Measure time in real time instead of CPU time. It can be useful
when testing speed of hardware engines.
Use the specified cipher or message digest algorithm via the EVP
Time the decryption instead of encryption. Affects only the EVP
[zero or more test algorithms]
If any options are given, speed tests those algorithms, otherwise
all of the above are tested.
