openssl-engine, engine - load and query engines
openssl engine [ engine... ] [-v] [-vv]
[-vvv] [-vvv] [-vvv] [-c] [-t] [-tt]
[-pre command] [-post command] [ engine...
]
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.
- -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.
