=head1 DESCRIPTION
|
|
|
|
This command processes public key algorithm parameters.
|
|
They can be checked for correctness and their components printed out.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.
|
|
|
|
=item B<-in> I<filename>
|
|
|
|
This specifies the input file to read parameters from or standard input if
|
|
this option is not specified.
|
|
|
|
=item B<-out> I<filename>
|
|
|
|
This specifies the output filename to write parameters to or standard output if
|
|
this option is not specified.
|
|
The output filename can be the same as the input filename,
|
|
which leads to replacing the file contents.
|
|
Note that file I/O is not atomic. The output file is truncated and then written.
|
|
|
|
=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<-check>
|
|
|
|
This option checks the correctness of parameters.

|
=head1 EXAMPLES
|
|
|
|
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.
