.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "OPENSSL-SPEED 1ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
openssl-speed - test library performance Header "SYNOPSIS" \fBopenssl speed [-help] [-elapsed] [-evp algo] [-hmac algo] [-cmac algo] [-mb] [-aead] [-multi num] [-async_jobs num] [-misalign num] [-decrypt] [-primes num] [-seconds num] [-bytes num] [-mr] [-rand files] [-writerand file] [-engine id] [-provider name] [-provider-path path] [-propquery propq] [algorithm ...] Header "DESCRIPTION" This command is used to test the performance of cryptographic algorithms. Header "OPTIONS" Item "-help" Print out a usage message. Item "-elapsed" When calculating operations- or bytes-per-second, use wall-clock time instead of \s-1CPU\s0 user time as divisor. It can be useful when testing speed of hardware engines. Item "-evp algo" Use the specified cipher or message digest algorithm via the \s-1EVP\s0 interface. If algo is an \s-1AEAD\s0 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. .Sp To see the algorithms supported with this option, use \f(CW\*(C`openssl list -digest-algorithms\*(C' or \*(C`openssl list -cipher-algorithms\*(C' command. Item "-multi num" Run multiple operations in parallel. Item "-async_jobs num" Enable async mode and start specified number of jobs. Item "-misalign num" Misalign the buffers by the specified number of bytes. Item "-hmac digest" Time the \s-1HMAC\s0 algorithm using the specified message digest. Item "-cmac cipher" Time the \s-1CMAC\s0 algorithm using the specified cipher e.g. \f(CW\*(C`openssl speed -cmac aes128\*(C'. Item "-decrypt" Time the decryption instead of encryption. Affects only the \s-1EVP\s0 testing. Item "-mb" Enable multi-block mode on EVP-named cipher. Item "-aead" Benchmark EVP-named \s-1AEAD\s0 cipher in TLS-like sequence. Item "-primes num" Generate a num-prime \s-1RSA\s0 key and use it to run the benchmarks. This option is only effective if \s-1RSA\s0 algorithm is specified to test. Item "-seconds num" Run benchmarks for num seconds. Item "-bytes num" Run benchmarks on num-byte buffers. Affects ciphers, digests and the \s-1CSPRNG.\s0 The limit on the size of the buffer is \s-1INT_MAX\s0 - 64 bytes, which for a 32-bit int would be 2147483583 bytes. Item "-mr" Produce the summary in a mechanical, machine-readable, format. Item "-rand files, -writerand file" See \*(L"Random State Options\*(R" in openssl\|(1) for details. Item "-engine id" See \*(L"Engine Options\*(R" in openssl\|(1). This option is deprecated. Item "-provider name"

0

Item "-provider-path path" Item "-propquery propq"

See \*(L"Provider Options\*(R" in openssl\|(1), provider\|(7), and property\|(7).

Item "algorithm ..." If any algorithm is given, then those algorithms are tested, otherwise a pre-compiled grand selection is tested. Header "BUGS" The algorithm can be selected only from a pre-compiled subset of things that the \*(C`openssl speed\*(C' command knows about. To test any additional digest or cipher algorithm supported by OpenSSL use the \*(C`-evp\*(C' option.

There is no way to test the speed of any additional public key algorithms supported by third party providers with the \*(C`openssl speed\*(C' command.
