NAMEopenssl−engine − load and query engines
SYNOPSIS​openssl engine [−help] [−v] [−vv] [−vvv] [−vvvv] [−c] [−t] [−tt] [−pre command] ... [−post command] ... [engine ...]
DESCRIPTIONThis 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.
EXAMPLESTo 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
ENVIRONMENTOPENSSL_ENGINES The path to the engines directory.
