5 pkeyparam - public key algorithm parameter processing tool
9 B<openssl> B<pkeyparam>
19 The B<pkey> command processes public or private keys. They can be converted
20 between various forms and their components printed out.
22 =head1 COMMAND OPTIONS
28 Print out a usage message.
32 This specifies the input filename to read parameters from or standard input if
33 this option is not specified.
35 =item B<-out filename>
37 This specifies the output filename to write parameters to or standard output if
38 this option is not specified.
42 prints out the parameters in plain text in addition to the encoded version.
46 do not output the encoded version of the parameters.
50 specifying an engine (by its unique B<id> string) will cause B<pkeyparam>
51 to attempt to obtain a functional reference to the specified engine,
52 thus initialising it if needed. The engine will then be set as the default
53 for all available algorithms.
59 Print out text version of parameters:
61 openssl pkeyparam -in param.pem -text
65 There are no B<-inform> or B<-outform> options for this command because only
66 PEM format is supported because the key type is determined by the PEM headers.
