=pod =head1 NAME openssl-pkeyparam, pkeyparam - public key algorithm parameter processing tool =head1 SYNOPSIS B<openssl> B<pkeyparam> [B<-help>] [B<-in filename>] [B<-out filename>] [B<-text>] [B<-noout>] [B<-engine id>] [B<-check>] =head1 DESCRIPTION The B<pkeyparam> 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 filename> This specifies the input filename to read parameters from or standard input if this option is not specified. =item B<-out 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 id> Specifying an engine (by its unique B<id> string) will cause B<pkeyparam> 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. =head1 SEE ALSO L<genpkey(1)>, L<rsa(1)>, L<pkcs8(1)>, L<dsa(1)>, L<genrsa(1)>, L<gendsa(1)> =head1 COPYRIGHT Copyright 2006-2019 The OpenSSL Project Authors.
