NAME

6       openssl-speed, speed - test library performance
7

SYNOPSIS

9       openssl speed [-help] [-engine id] [-elapsed] [-evp algo] [-decrypt]
10       [-rand file...]  [-writerand file] [-primes num] [-seconds num] [-bytes
11       num] [algorithm...]
12

DESCRIPTION

14       This command is used to test the performance of cryptographic
15       algorithms.  To see the list of supported algorithms, use the list
16       --digest-commands or list --cipher-commands command. The global CSPRNG
17       is denoted by the rand algorithm name.
18

OPTIONS

20       -help
21           Print out a usage message.
22
23       -engine id
24           Specifying an engine (by its unique id string) will cause speed to
25           attempt to obtain a functional reference to the specified engine,
26           thus initialising it if needed. The engine will then be set as the
27           default for all available algorithms.
28
29       -elapsed
30           When calculating operations- or bytes-per-second, use wall-clock
31           time instead of CPU user time as divisor. It can be useful when
32           testing speed of hardware engines.
33
34       -evp algo
35           Use the specified cipher or message digest algorithm via the EVP
36           interface.  If algo is an AEAD cipher, then you can pass <-aead> to
37           benchmark a TLS-like sequence. And if algo is a multi-buffer
38           capable cipher, e.g.  aes-128-cbc-hmac-sha1, then -mb will time
39           multi-buffer operation.
40
41       -decrypt
42           Time the decryption instead of encryption. Affects only the EVP
43           testing.
44
45       -rand file...
46           A file or files containing random data used to seed the random
47           number generator.  Multiple files can be specified separated by an
48           OS-dependent character.  The separator is ; for MS-Windows, , for
49           OpenVMS, and : for all others.
50
51       [-writerand file]
52           Writes random data to the specified file upon exit.  This can be
53           used with a subsequent -rand flag.
54
55       -primes num
56           Generate a num-prime RSA key and use it to run the benchmarks. This
57           option is only effective if RSA algorithm is specified to test.
58
59       -seconds num
60           Run benchmarks for num seconds.
61
62       -bytes num
63           Run benchmarks on num-byte buffers. Affects ciphers, digests and
64           the CSPRNG.
65
66       [zero or more test algorithms]
67           If any options are given, speed tests those algorithms, otherwise a
68           pre-compiled grand selection is tested.
