It was also used by Netscape certificate server. 28 29=head1 OPTIONS 30 31=over 4 32 33=item B<-help> 34 35Print out a usage message. 36 37=item B<-in> I<filename> 38 39This specifies the input filename to read or standard input if this 40option is not specified. 41 42=item B<-out> I<filename> 43 44Specifies the output filename or standard output by default. 45 46=item B<-toseq> 47 48Normally a Netscape certificate sequence will be input and the output 49is the certificates contained in it. With the B<-toseq> option the 50situation is reversed: a Netscape certificate sequence is created from 51a file of certificates. 52 53{- $OpenSSL::safe::opt_provider_item -} 54 55=back 56 57=head1 EXAMPLES 58 59Output the certificates in a Netscape certificate sequence 60 61 openssl nseq -in nseq.pem -out certs.pem 62 63Create a Netscape certificate sequence 64 65 openssl nseq -in certs.pem -toseq -out nseq.pem 66 67=head1 COPYRIGHT 68 69Copyright 2000-2020 The OpenSSL Project Authors.
