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

BUGS

93       The algorithm can be selected only from a pre-compiled subset of things
94       that the "openssl speed" command knows about. To test any additional
95       digest or cipher algorithm supported by OpenSSL use the "-evp" option.
96
97       There is no way to test the speed of any additional public key
98       algorithms supported by third party providers with the "openssl speed"
99       command.

HISTORY

102       The -engine option was deprecated in OpenSSL 3.0.
