| =head1 NAME |
| |
| pkeyparam - public key algorithm parameter processing tool |
| |
| =head1 SYNOPSIS |
| |
| B<openssl> B<pkeyparam> |
| [B<-in filename>] |
| [B<-out filename>] |
| [B<-text>] |
| [B<-noout>] |
| [B<-engine id>] |
| |
| =head1 DESCRIPTION |
| |
| The B<pkey> command processes public or private keys. They can be converted |
| between various forms and their components printed out. |
| |
| =head1 COMMAND OPTIONS |
| |
| =over 4 |
| |
| =item B<-in filename> |
| |
| This specifies the input filename to read parameters from or standard input if |
| this option is not specified. |
| |
| =item B<-out filename> |
| |
| This specifies the output filename to write parameters to or standard output if |
| this option is not specified. |
| |
| =item B<-text> |
| |
| prints out the parameters in plain text in addition to the encoded version. |
| |
| =item B<-noout> |
| |
| do not output the encoded version of the parameters. |
| |
| =item B<-engine id> |
| |
| specifying an engine (by its unique B<id> string) will cause B<pkeyparam> |
| to attempt to obtain a functional reference to the specified engine, |
| thus initialising it if needed. The engine will then be set as the default |
| for all available algorithms. |
| |
| =back |
| |
| =head1 EXAMPLE |
| |
| Print out text version of parameters: |
| |
| openssl pkeyparam -in param.pem -text |
| |
| =head1 NOTES |
| |
| There are no B<-inform> or B<-outform> options for this command because only |
| PEM format is supported because the key type is determined by the PEM headers. |
