openssl-engine - load and query engines
 |

=head1 SYNOPSIS
 |

 | 
						|
B<openssl engine>
 | 
						|
[B<-v>]
 | 
						|
[B<-vv>]
 | 
						|
[B<-vvv>]
 | 
						|
[B<-vvvv>]
 |

 | 
						|
[I<engine> ...]
 | 
						|
 | 
						|
=head1 DESCRIPTION
 | 
						|
 | 
						|
This command is used to query the status and capabilities
 | 
						|
of the specified I<engine>s.
 | 
						|
Engines may be specified before and after all other command-line flags.
 | 
						|
Only those specified are queried.
 | 
						|
 | 
						|
=head1 OPTIONS
 | 
						|
 | 
						|
=over 4
 | 
						|
 | 
						|
=item B<-v> B<-vv> B<-vvv> B<-vvvv>
 | 
						|
 | 
						|
Provides information about each specified engine. The first flag lists
 | 
						|
all the possible run-time control commands; the second adds a
 | 
						|
description of each command; the third adds the input flags, and the
 | 
						|
final option adds the internal input flags.
 | 
						|
 | 
						|
=item B<-c>
 | 
						|
 | 
						|
Lists the capabilities of each engine.
 | 
						|
 | 
						|
=item B<-t>
 | 
						|
 | 
						|
Tests if each specified engine is available, and displays the answer.
 | 
						|
 | 
						|
=item B<-tt>
 | 
						|
 | 
						|
Displays an error trace for any unavailable engine.
 | 
						|
 | 
						|
=item B<-pre> I<command>
 | 
						|
 | 
						|
=item B<-post> I<command>
 | 
						|
 | 
						|
Command-line configuration of engines.
 | 
						|
The B<-pre> command is given to the engine before it is loaded and
 | 
						|
the B<-post> command is given after the engine is loaded.
 | 
						|
The I<command> is of the form I<cmd>:I<val> where I<cmd> is the command,
 | 
						|
and I<val> is the value for the command.
 | 
						|
See the example below.
 | 
						|
 | 
						|
These two options are cumulative, so they may be given more than once in the
 | 
						|
same command.
