NAME

6       openssl-engine - load and query engines
7

SYNOPSIS

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

DESCRIPTION

13       This command has been deprecated.  Providers should be used instead of
14       engines.
15
16       This command is used to query the status and capabilities of the
17       specified engines.  Engines may be specified before and after all other
18       command-line flags.  Only those specified are queried.
19

OPTIONS

21       -help
22           Display an option summary.
23
24       -v -vv -vvv -vvvv
25           Provides information about each specified engine. The first flag
26           lists all the possible run-time control commands; the second adds a
27           description of each command; the third adds the input flags, and
28           the final option adds the internal input flags.
29
30       -c  Lists the capabilities of each engine.
31
32       -t  Tests if each specified engine is available, and displays the
33           answer.
34
35       -tt Displays an error trace for any unavailable engine.
36
37       -pre command
38       -post command
39           Command-line configuration of engines.  The -pre command is given
40           to the engine before it is loaded and the -post command is given
41           after the engine is loaded.  The command is of the form cmd:val
42           where cmd is the command, and val is the value for the command.
43           See the example below.
44
45           These two options are cumulative, so they may be given more than
46           once in the same command.
47

EXAMPLES

49       To list all the commands available to a dynamic engine:
50
51        $ openssl engine -t -tt -vvvv dynamic
52        (dynamic) Dynamic engine loading support
53             [ unavailable ]
54             SO_PATH: Specifies the path to the new ENGINE shared library
55                  (input flags): STRING
56             NO_VCHECK: Specifies to continue even if version checking fails (boolean)
57                  (input flags): NUMERIC
58             ID: Specifies an ENGINE id name for loading
59                  (input flags): STRING
60             LIST_ADD: Whether to add a loaded ENGINE to the internal list (0=no,1=yes,2=mandatory)
61                  (input flags): NUMERIC
62             DIR_LOAD: Specifies whether to load from 'DIR_ADD' directories (0=no,1=yes,2=mandatory)
63                  (input flags): NUMERIC
64             DIR_ADD: Adds a directory from which ENGINEs can be loaded
65                  (input flags): STRING
66             LOAD: Load up the ENGINE specified by other settings
67                  (input flags): NO_INPUT
68
69       To list the capabilities of the rsax engine:
70
71        $ openssl engine -c
72        (rsax) RSAX engine support
73         [RSA]
74        (dynamic) Dynamic engine loading support
