DESCRIPTION

16       This command is used to test the performance of cryptographic
17       algorithms.
18

OPTIONS

20       -help
21           Print out a usage message.
22
23       -config filename
24           Specifies the configuration file to use.  Optional; for a
25           description of the default value, see "COMMAND SUMMARY" in
26           openssl(1).
27
28       -elapsed
29           When calculating operations- or bytes-per-second, use wall-clock
30           time instead of CPU user time as divisor. It can be useful when
31           testing speed of hardware engines.
32
33       -evp algo
34           Use the specified cipher or message digest algorithm via the EVP
35           interface.  If algo is an AEAD cipher, then you can pass -aead to
36           benchmark a TLS-like sequence. And if algo is a multi-buffer
37           capable cipher, e.g.  aes-128-cbc-hmac-sha1, then -mb will time
38           multi-buffer operation.
39
40           To see the algorithms supported with this option, use "openssl list
41           -digest-algorithms" or "openssl list -cipher-algorithms" command.
42
43       -multi num
44           Run multiple operations in parallel.
45
46       -async_jobs num
47           Enable async mode and start specified number of jobs.
48
49       -misalign num
50           Misalign the buffers by the specified number of bytes.
51
52       -hmac digest
53           Time the HMAC algorithm using the specified message digest.
54
55       -cmac cipher
56           Time the CMAC algorithm using the specified cipher e.g.  "openssl
57           speed -cmac aes128".
58
59       -decrypt
60           Time the decryption instead of encryption. Affects only the EVP
61           testing.
62
63       -mb Enable multi-block mode on EVP-named cipher.
64
65       -aead
66           Benchmark EVP-named AEAD cipher in TLS-like sequence.
67
68       -primes num
69           Generate a num-prime RSA key and use it to run the benchmarks. This
70           option is only effective if RSA algorithm is specified to test.
71
72       -seconds num
73           Run benchmarks for num seconds.
74
75       -bytes num
76           Run benchmarks on num-byte buffers. Affects ciphers, digests and
77           the CSPRNG.  The limit on the size of the buffer is INT_MAX - 64
78           bytes, which for a 32-bit int would be 2147483583 bytes.
79
80       -mr Produce the summary in a mechanical, machine-readable, format.
81
82       -mlock
83           Lock memory into RAM for more deterministic measurements.
84
85       -rand files, -writerand file
86           See "Random State Options" in openssl(1) for details.
87
88       -engine id
89           See "Engine Options" in openssl(1).  This option is deprecated.
90
91       -provider name
92       -provider-path path
93       -propquery propq
94           See "Provider Options" in openssl(1), provider(7), and property(7).
95
96       algorithm ...
97           If any algorithm is given, then those algorithms are tested,
98           otherwise a pre-compiled grand selection is tested.
99

BUGS

101       The algorithm can be selected only from a pre-compiled subset of things
102       that the "openssl speed" command knows about. To test any additional
103       digest or cipher algorithm supported by OpenSSL use the "-evp" option.
104
105       There is no way to test the speed of any additional public key
106       algorithms supported by third party providers with the "openssl speed"
107       command.
108

HISTORY

110       The -engine option was deprecated in OpenSSL 3.0.
