Providers should be used instead of engines. 26 27This command is used to query the status and capabilities 28of the specified I<engine>s. 29Engines may be specified before and after all other command-line flags. 30Only those specified are queried. 31 32=head1 OPTIONS 33 34=over 4 35 36=item B<-help> 37 38Display an option summary. 39 40=item B<-v> B<-vv> B<-vvv> B<-vvvv> 41 42Provides information about each specified engine. The first flag lists 43all the possible run-time control commands; the second adds a 44description of each command; the third adds the input flags, and the 45final option adds the internal input flags. 46 47=item B<-c> 48 49Lists the capabilities of each engine. 50 51=item B<-t> 52 53Tests if each specified engine is available, and displays the answer. 54 55=item B<-tt> 56 57Displays an error trace for any unavailable engine. 58 59=item B<-pre> I<command> 60 61=item B<-post> I<command> 62 63Command-line configuration of engines. 64The B<-pre> command is given to the engine before it is loaded and 65the B<-post> command is given after the engine is loaded. 66The I<command> is of the form I<cmd>:I<val> where I<cmd> is the command, 67and I<val> is the value for the command. 68See the example below. 69 70These two options are cumulative, so they may be given more than once in the 71same command. 72 73=back 74 75=head1 EXAMPLES 76 77To list all the commands available to a dynamic engine: 78 79 $ openssl engine -t -tt -vvvv dynamic 80 (dynamic) Dynamic engine loading support 81 [ unavailable ] 82 SO_PATH: Specifies the path to the new ENGINE shared library 83 (input flags): STRING 84 NO_VCHECK: Specifies to continue even if version checking fails (boolean) 85 (input flags): NUMERIC 86 ID: Specifies an ENGINE id name for loading 87 (input flags): STRING 88 LIST_ADD: Whether to add a loaded ENGINE to the internal list (0=no,1=yes,2=mandatory) 89 (input flags): NUMERIC 90 DIR_LOAD: Specifies whether to load from 'DIR_ADD' directories (0=no,1=yes,2=mandatory) 91 (input flags): NUMERIC 92 DIR_ADD: Adds a directory from which ENGINEs can be loaded 93 (input flags): STRING 94 LOAD: Load up the ENGINE specified by other settings 95 (input flags): NO_INPUT 96 97To list the capabilities of the B<rsax> engine: 98 99 $ openssl engine -c 100 (rsax) RSAX engine support 101 [RSA] 102 (dynamic) Dynamic engine loading support 103 104=head1 ENVIRONMENT 105 106=over 4 107 108=item B<OPENSSL_ENGINES> 109 110The path to the engines directory. 111 112=back 113 114=head1 SEE ALSO 115 116L<openssl(1)>, 117L<config(5)> 118 119=head1 HISTORY 120 121This command was deprecated in OpenSSL 3.0. 122 123=head1 COPYRIGHT 124 125Copyright 2016-2020 The OpenSSL Project Authors.
