NAME

openssl-speed, speed - test library performance

SYNOPSIS

openssl speed [-help] [-engine id] [-elapsed] [-evp algo] [-decrypt] [-rand file...] [-writerand file] [-primes num] [algorithm...]

DESCRIPTION

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.

OPTIONS

-help

Print out a usage message.

-engine id

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.

-elapsed

Measure time in real time instead of CPU time. It can be useful when testing speed of hardware engines.

-evp algo

Use the specified cipher or message digest algorithm via the EVP interface.

-decrypt

Time the decryption instead of encryption. Affects only the EVP testing.

-rand file...

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.

[-writerand file]

Writes random data to the specified file upon exit. This can be used with a subsequent -rand flag.

-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 bechmarks for num seconds.

-bytes num

Run bechmarks on num-byte buffers. Affects ciphers, digests and the CSPRNG.

[zero or more test algorithms]

If any options are given, speed tests those algorithms, otherwise all of the above are tested.
