openssl engine -- load and query engines

SYNOPSIS

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

DESCRIPTION

This command has been deprecated. Providers should be used instead of engines.

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

-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.
