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.

To list all the commands available to a dynamic engine:

$ openssl engine -t -tt -vvvv dynamic (dynamic) Dynamic engine loading support [ unavailable ] SO_PATH: Specifies the path to the new ENGINE shared library (input flags): STRING NO_VCHECK: Specifies to continue even if version checking fails (boolean) (input flags): NUMERIC ID: Specifies an ENGINE id name for loading (input flags): STRING LIST_ADD: Whether to add a loaded ENGINE to the internal list (0=no,1=yes,2=mandatory) (input flags): NUMERIC DIR_LOAD: Specifies whether to load from DIR_ADD directories (0=no,1=yes,2=mandatory) (input flags): NUMERIC DIR_ADD: Adds a directory from which ENGINEs can be loaded (input flags): STRING LOAD: Load up the ENGINE specified by other settings (input flags): NO_INPUT

To list the capabilities of the rsax engine:

$ openssl engine -c (rsax) RSAX engine support [RSA] (dynamic) Dynamic engine loading support
