| =head1 NAME |
| |
| openssl-nseq, |
| nseq - create or examine a Netscape certificate sequence |
| |
| =head1 SYNOPSIS |
| |
| B<openssl> B<nseq> |
| [B<-help>] |
| [B<-in filename>] |
| [B<-out filename>] |
| [B<-toseq>] |
| |
| =head1 DESCRIPTION |
| |
| The B<nseq> 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<PEM> 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. |
