- =head1 NAME
- openssl-pkeyparam - public key algorithm parameter processing tool
- =head1 SYNOPSIS
- B<openssl> B<pkeyparam>
- [B<-help>]
- [B<-in> I<filename>]
- [B<-out> I<filename>]
- [B<-text>]
- [B<-noout>]
- [B<-engine> I<id>]
- [B<-check>]
- =for openssl ifdef engine
- =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 filename 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.
- =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> I<id>
- Specifying an engine (by its unique I<id> string) will cause this command
- 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.
- =item B<-check>
- This option checks the correctness of parameters.
- =back
- =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.
