=head1 NAME
openssl-speed,
speed - test library performance
=head1 SYNOPSIS
B<openssl speed>
[B<-help>]
[B<-engine id>]
[B<-elapsed>]
[B<-evp algo>]
[B<-decrypt>]
[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<[zero or more test algorithms]>
If any options are given, B<speed> tests those algorithms, otherwise all of
the above are tested.
