The output file is truncated and then written. 48 49=item B<-text> 50 51Prints out the parameters in plain text in addition to the encoded version. 52 53=item B<-noout> 54 55Do not output the encoded version of the parameters. 56 57=item B<-check> 58 59This option checks the correctness of parameters. 60 61{- $OpenSSL::safe::opt_engine_item -} 62 63{- $OpenSSL::safe::opt_provider_item -} 64 65=back 66 67=head1 EXAMPLES 68 69Print out text version of parameters: 70 71 openssl pkeyparam -in param.pem -text 72 73=head1 NOTES 74 75There are no B<-inform> or B<-outform> options for this command because only 76PEM format is supported because the key type is determined by the PEM headers. 77 78=head1 SEE ALSO 79 80L<openssl(1)>, 81L<openssl-genpkey(1)>, 82L<openssl-rsa(1)>, 83L<openssl-pkcs8(1)>, 84L<openssl-dsa(1)>, 85L<openssl-genrsa(1)>, 86L<openssl-gendsa(1)> 87 88=head1 HISTORY 89 90The B<-engine> option was deprecated in OpenSSL 3.0. 91 92=head1 COPYRIGHT 93 94Copyright 2006-2021 The OpenSSL Project Authors.
