openssl-speed,
|
|
speed - test library performance

=head1 SYNOPSIS
|
|
|
|
B<openssl speed>
|
|
[B<-help>]
|
|
[B<-engine id>]
|
|
[B<-elapsed>]
|
|
[B<-evp algo>]
|
|

|
=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. The global CSPRNG is denoted by
|
|
the I<rand> algorithm name.
|
|
|
|
=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.
