1=pod 2 3=head1 NAME 4 5openssl-nseq, 6nseq - create or examine a Netscape certificate sequence 7 8=head1 SYNOPSIS 9 10B<openssl> B<nseq> 11[B<-help>] 12[B<-in filename>] 13[B<-out filename>] 14[B<-toseq>] 15 16=head1 DESCRIPTION 17 18The B<nseq> command takes a file containing a Netscape certificate 19sequence and prints out the certificates contained in it or takes a 20file of certificates and converts it into a Netscape certificate 21sequence. 22 23=head1 OPTIONS 24 25=over 4 26 27=item B<-help> 28 29Print out a usage message. 30 31=item B<-in filename> 32 33This specifies the input filename to read or standard input if this 34option is not specified. 35 36=item B<-out filename> 37 38Specifies the output filename or standard output by default. 39 40=item B<-toseq> 41 42Normally a Netscape certificate sequence will be input and the output 43is the certificates contained in it. With the B<-toseq> option the 44situation is reversed: a Netscape certificate sequence is created from 45a file of certificates. 46 47=back 48 49=head1 EXAMPLES 50 51Output the certificates in a Netscape certificate sequence 52 53 openssl nseq -in nseq.pem -out certs.pem 54 55Create a Netscape certificate sequence 56 57 openssl nseq -in certs.pem -toseq -out nseq.pem 58 59=head1 NOTES 60 61The B<PEM> encoded form uses the same headers and footers as a certificate: 62 63 -----BEGIN CERTIFICATE----- 64 -----END CERTIFICATE----- 65 66A Netscape certificate sequence is a Netscape specific format that can be sent 67to browsers as an alternative to the standard PKCS#7 format when several 68certificates are sent to the browser: for example during certificate enrollment. 69It is used by Netscape certificate server for example. 70 71=head1 BUGS 72 73This program needs a few more options: like allowing DER or PEM input and 74output files and allowing multiple certificate files to be used. 75 76=head1 COPYRIGHT 77 78Copyright 2000-2017 The OpenSSL Project Authors.
