  26 =head1 DESCRIPTION
  27
  28 This command is used to test the performance of cryptographic algorithms.
  29 To see the list of supported algorithms, use C<openssl list -digest-commands>
  30 or C<openssl list -cipher-commands> command. The global CSPRNG is denoted by
  31 the B<rand> algorithm name.

  33 =head1 OPTIONS
  34
  35 =over 4
  36
  37 =item B<-help>
  38
  39 Print out a usage message.
  40
  41 =item B<-engine> I<id>
  42
  43 Specifying an engine (by its unique I<id> string) will cause this command
  44 to attempt to obtain a functional reference to the specified engine,
  45 thus initialising it if needed. The engine will then be set as the default
  46 for all available algorithms.
  47
  48 =item B<-elapsed>
  49
  50 When calculating operations- or bytes-per-second, use wall-clock time
  51 instead of CPU user time as divisor. It can be useful when testing speed
  52 of hardware engines.
  53
  54 =item B<-evp> I<algo>
  55
  56 Use the specified cipher or message digest algorithm via the EVP interface.
  57 If I<algo> is an AEAD cipher, then you can pass B<-aead> to benchmark a
  58 TLS-like sequence. And if I<algo> is a multi-buffer capable cipher, e.g.
  59 aes-128-cbc-hmac-sha1, then B<-mb> will time multi-buffer operation.
  60
  61 =item B<-hmac> I<digest>
  62
  63 Time the HMAC algorithm using the specified message digest.
  64
  65 =item B<-cmac> I<cipher>
  66
  67 Time the CMAC algorithm using the specified cipher e.g.
  68 C<openssl speed -cmac aes128>.
  69
  70 =item B<-decrypt>
  71
  72 Time the decryption instead of encryption. Affects only the EVP testing.
  73
  74 =item B<-primes> I<num>
  75
  76 Generate a I<num>-prime RSA key and use it to run the benchmarks. This option
  77 is only effective if RSA algorithm is specified to test.
  78
  79 =item B<-seconds> I<num>
  80
  81 Run benchmarks for I<num> seconds.
  82
  83 =item B<-bytes> I<num>
  84
  85 Run benchmarks on I<num>-byte buffers. Affects ciphers, digests and the CSPRNG.
  86
  87 {- $OpenSSL::safe::opt_r_item -}
  88
  89 =item I<algorithm> ...
  90
  91 If any I<algorithm> is given, then those algorithms are tested, otherwise a
  92 pre-compiled grand selection is tested.
