NAME

openssl-engine, engine - load and query engines  

SYNOPSIS

openssl engine [ engine... ] [-v] [-vv] [-vvv] [-vvv] [-vvv] [-c] [-t] [-tt] [-pre command] [-post command] [ engine... ]  

DESCRIPTION

The engine command is used to query the status and capabilities of the specified engine's. Engines may be specified before and after all other command-line flags. Only those specified are queried.  

OPTIONS

-v -vv -vvv -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.
-c
Lists the capabilities of each engine.
-t
Tests if each specified engine is available, and displays the answer.
-tt
Displays an error trace for any unavailable engine.
-pre command
-post command
Command-line configuration of engines. The -pre command is given to the engine before it is loaded and the -post command is given after the engine is loaded. The command is of the form cmd:val where cmd is the command, and val is the value for the command. See the example below.
