18
19The B<pkey> command processes public or private keys. They can be converted
20between various forms and their components printed out.

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

53=head1 EXAMPLE

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