6 speed - test library performance
23 This command is used to test the performance of cryptographic algorithms.
24 To see the list of supported algorithms, use the I<list --digest-commands>
25 or I<list --cipher-commands> command. The global CSPRNG is denoted by
26 the I<rand> algorithm name.
34 Print out a usage message.
38 Specifying an engine (by its unique B<id> string) will cause B<speed>
39 to attempt to obtain a functional reference to the specified engine,
40 thus initialising it if needed. The engine will then be set as the default
41 for all available algorithms.
45 Measure time in real time instead of CPU time. It can be useful when testing
46 speed of hardware engines.
50 Use the specified cipher or message digest algorithm via the EVP interface.
54 Time the decryption instead of encryption. Affects only the EVP testing.
56 =item B<-rand file...>
58 A file or files containing random data used to seed the random number
60 Multiple files can be specified separated by an OS-dependent character.
61 The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
64 =item [B<-writerand file>]
66 Writes random data to the specified I<file> upon exit.
67 This can be used with a subsequent B<-rand> flag.
71 Generate a B<num>-prime RSA key and use it to run the benchmarks. This option
72 is only effective if RSA algorithm is specified to test.
76 Run benchmarks for B<num> seconds.
80 Run benchmarks on B<num>-byte buffers. Affects ciphers, digests and the CSPRNG.
82 =item B<[zero or more test algorithms]>
84 If any options are given, B<speed> tests those algorithms, otherwise all of
