=pod =head1 NAME openssl-nseq, nseq - create or examine a Netscape certificate sequence =head1 SYNOPSIS B B [B<-help>] [B<-in filename>] [B<-out filename>] [B<-toseq>] =head1 DESCRIPTION The B command takes a file containing a Netscape certificate sequence and prints out the certificates contained in it or takes a file of certificates and converts it into a Netscape certificate sequence. =head1 OPTIONS =over 4 =item B<-help> Print out a usage message. =item B<-in filename> This specifies the input filename to read or standard input if this option is not specified. =item B<-out filename> Specifies the output filename or standard output by default. =item B<-toseq> Normally a Netscape certificate sequence will be input and the output is the certificates contained in it. With the B<-toseq> option the situation is reversed: a Netscape certificate sequence is created from a file of certificates. =back =head1 EXAMPLES Output the certificates in a Netscape certificate sequence openssl nseq -in nseq.pem -out certs.pem Create a Netscape certificate sequence openssl nseq -in certs.pem -toseq -out nseq.pem =head1 NOTES The B encoded form uses the same headers and footers as a certificate: -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- A Netscape certificate sequence is a Netscape specific format that can be sent to browsers as an alternative to the standard PKCS#7 format when several certificates are sent to the browser: for example during certificate enrollment. It is used by Netscape certificate server for example. =head1 BUGS This program needs a few more options: like allowing DER or PEM input and output files and allowing multiple certificate files to be used. =head1 COPYRIGHT Copyright 2000-2017 The OpenSSL Project Authors.
