32 This command is used to test the performance of cryptographic algorithms.
40 Print out a usage message.
44 When calculating operations- or bytes-per-second, use wall-clock time
45 instead of CPU user time as divisor. It can be useful when testing speed
50 Use the specified cipher or message digest algorithm via the EVP interface.
51 If I<algo> is an AEAD cipher, then you can pass B<-aead> to benchmark a
52 TLS-like sequence. And if I<algo> is a multi-buffer capable cipher, e.g.
53 aes-128-cbc-hmac-sha1, then B<-mb> will time multi-buffer operation.
55 To see the algorithms supported with this option, use
56 C<openssl list -digest-algorithms> or C<openssl list -cipher-algorithms>
59 =item B<-multi> I<num>
61 Run multiple operations in parallel.
63 =item B<-async_jobs> I<num>
65 Enable async mode and start specified number of jobs.
67 =item B<-misalign> I<num>
69 Misalign the buffers by the specified number of bytes.
71 =item B<-hmac> I<digest>
73 Time the HMAC algorithm using the specified message digest.
75 =item B<-cmac> I<cipher>
77 Time the CMAC algorithm using the specified cipher e.g.
78 C<openssl speed -cmac aes128>.
82 Time the decryption instead of encryption. Affects only the EVP testing.
84 =item B<-primes> I<num>
86 Generate a I<num>-prime RSA key and use it to run the benchmarks. This option
87 is only effective if RSA algorithm is specified to test.
89 =item B<-seconds> I<num>
91 Run benchmarks for I<num> seconds.
93 =item B<-bytes> I<num>
95 Run benchmarks on I<num>-byte buffers. Affects ciphers, digests and the CSPRNG.
99 Produce the summary in a mechanical, machine-readable, format.

107 =item I<algorithm> ...
109 If any I<algorithm> is given, then those algorithms are tested, otherwise a
110 pre-compiled grand selection is tested.
116 The I<algorithm> can be selected only from a pre-compiled subset of things
117 that the C<openssl speed> command knows about. To test any additional digest
118 or cipher algorithm supported by OpenSSL use the C<-evp> option.
120 There is no way to test the speed of any additional public key algorithms
121 supported by third party providers with the C<openssl speed> command.
125 The B<-engine> option was deprecated in OpenSSL 3.0.
