NAME
openssl-engine - load and query engines
SYNOPSIS
openssl engine [-help] [-v] [-vv] [-vvv] [-vvvv] [-c] [-t] [-tt] [-pre
command] ... [-post command] ... [engine ...]
DESCRIPTION
This command has been deprecated. Providers should be used instead of
engines.
This command is used to query the status and capabilities of the
specified engines. Engines may be specified before and after all other
command-line flags. Only those specified are queried.
OPTIONS
-help
Display an option summary.
-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.
These two options are cumulative, so they may be given more than
once in the same command.
