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. COPYRIGHT
