.\" way too many mistakes in technical documents.

.SH "NAME"
openssl\-nseq, nseq \- create or examine a Netscape certificate sequence
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBopenssl\fR \fBnseq\fR
[\fB\-help\fR]
[\fB\-in filename\fR]
[\fB\-out filename\fR]
[\fB\-toseq\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBnseq\fR 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.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-help\fR" 4
.IX Item "-help"
Print out a usage message.
.IP "\fB\-in filename\fR" 4
.IX Item "-in filename"
This specifies the input filename to read or standard input if this
option is not specified.
.IP "\fB\-out filename\fR" 4
.IX Item "-out filename"
Specifies the output filename or standard output by default.
.IP "\fB\-toseq\fR" 4
.IX Item "-toseq"
Normally a Netscape certificate sequence will be input and the output
is the certificates contained in it. With the \fB\-toseq\fR option the
situation is reversed: a Netscape certificate sequence is created from
a file of certificates.
.SH "EXAMPLES"
.IX Header "EXAMPLES"
Output the certificates in a Netscape certificate sequence
.PP

.SH "NOTES"
.IX Header "NOTES"
The \fB\s-1PEM\s0\fR encoded form uses the same headers and footers as a certificate:
.PP
.Vb 2
\& \-\-\-\-\-BEGIN CERTIFICATE\-\-\-\-\-
\& \-\-\-\-\-END CERTIFICATE\-\-\-\-\-
.Ve
.PP
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.
.SH "BUGS"
.IX Header "BUGS"
This program needs a few more options: like allowing \s-1DER\s0 or \s-1PEM\s0 input and
output files and allowing multiple certificate files to be used.
