11B<openssl> B<pkeyparam>

19
20The B<pkey> command processes public or private keys. They can be converted
21between various forms and their components printed out.
22
23=head1 COMMAND OPTIONS
24
25=over 4
26
27=item B<-in filename>
28
29This specifies the input filename to read parameters from or standard input if
30this option is not specified.
31
32=item B<-out filename>
33
34This specifies the output filename to write parameters to or standard output if
35this option is not specified.
36
37=item B<-text>
38
39prints out the parameters in plain text in addition to the encoded version. 
40
41=item B<-noout>
42
43do not output the encoded version of the parameters.
44
45=item B<-engine id>
46
47specifying an engine (by its unique B<id> string) will cause B<pkeyparam>
48to attempt to obtain a functional reference to the specified engine,
49thus initialising it if needed. The engine will then be set as the default
50for all available algorithms.

54=head1 EXAMPLE
55
56Print out text version of parameters:
57
58 openssl pkeyparam -in param.pem -text
59
60=head1 NOTES
61
62There are no B<-inform> or B<-outform> options for this command because only
63PEM format is supported because the key type is determined by the PEM headers.
