<p>openssl-nseq, nseq - create or examine a Netscape certificate sequence</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<p><b>openssl</b> <b>nseq</b> [<b>-help</b>] [<b>-in filename</b>] [<b>-out filename</b>] [<b>-toseq</b>]</p>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>The <b>nseq</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.</p>

<h1 id="OPTIONS">OPTIONS</h1>

<dl>

<p>Print out a usage message.</p>

</dd>
<dt id="in-filename"><b>-in filename</b></dt>
<dd>

<p>This specifies the input filename to read or standard input if this option is not specified.</p>

</dd>
<dt id="out-filename"><b>-out filename</b></dt>
<dd>

<p>Specifies the output filename or standard output by default.</p>

</dd>
<dt id="toseq"><b>-toseq</b></dt>
<dd>

<p>Normally a Netscape certificate sequence will be input and the output is the certificates contained in it. With the <b>-toseq</b> option the situation is reversed: a Netscape certificate sequence is created from a file of certificates.</p>

</dd>
</dl>

<h1 id="EXAMPLES">EXAMPLES</h1>

<p>Output the certificates in a Netscape certificate sequence</p>

<pre><code> openssl nseq -in nseq.pem -out certs.pem</code></pre>

<p>Create a Netscape certificate sequence</p>

<pre><code> openssl nseq -in certs.pem -toseq -out nseq.pem</code></pre>

<h1 id="NOTES">NOTES</h1>

<p>The <b>PEM</b> encoded form uses the same headers and footers as a certificate:</p>

<pre><code> -----BEGIN CERTIFICATE-----
 -----END CERTIFICATE-----</code></pre>

<p>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.</p>

<p>This program needs a few more options: like allowing DER or PEM input and output files and allowing multiple certificate files to be used.</p>
