| =head1 NAME |
| |
| speed - test library performance |
| |
| =head1 SYNOPSIS |
| |
| B<openssl speed> |
| [B<-help>] |
| [B<-engine id>] |
| [B<-elapsed>] |
| [B<-evp algo>] |
| [B<-decrypt>] |
| [B<-rand file...>] |
| [B<-writerand file>] |
| [B<algorithm...>] |
| |
| =head1 DESCRIPTION |
| |
| This command is used to test the performance of cryptographic algorithms. |
| To see the list of supported algorithms, use the I<list --digest-commands> |
| or I<list --cipher-commands> command. |
| |
| =head1 OPTIONS |
| |
| =over 4 |
| |
| =item B<-help> |
| |
| Print out a usage message. |
| |
| =item B<-engine id> |
| |
| Specifying an engine (by its unique B<id> string) will cause B<speed> |
| to attempt to obtain a functional reference to the specified engine, |
| thus initialising it if needed. The engine will then be set as the default |
| for all available algorithms. |
| |
| =item B<-elapsed> |
| |
| Measure time in real time instead of CPU time. It can be useful when testing |
| speed of hardware engines. |
| |
| =item B<-evp algo> |
| |
| Use the specified cipher or message digest algorithm via the EVP interface. |
| |
| =item B<-decrypt> |
| |
| Time the decryption instead of encryption. Affects only the EVP testing. |
| |
| =item B<-rand file...> |
| |
| A file or files containing random data used to seed the random number |
| generator. |
| Multiple files can be specified separated by an OS-dependent character. |
| The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for |
| all others. |
| |
| =item [B<-writerand file>] |
| |
| Writes random data to the specified I<file> upon exit. |
| This can be used with a subsequent B<-rand> flag. |
| |
| =item B<[zero or more test algorithms]> |
| |
| If any options are given, B<speed> tests those algorithms, otherwise all of |
| the above are tested. |
