SPEED(1SSL)							      OpenSSL							       SPEED(1SSL)

NAME

       openssl-speed, speed - test library performance

SYNOPSIS

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

       -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 benchmarks for num seconds.

       -bytes num
	   Run benchmarks 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 a pre-compiled grand selection is tested.
