<p>openssl-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</b> <i>filename</i>] [<b>-out</b> <i>filename</i>] [<b>-toseq</b>] [<b>-provider</b> <i>name</i>] [<b>-provider-path</b> <i>path</i>] [<b>-provparam</b> <i>[name:]key=value</i>] [<b>-propquery</b> <i>propq</i>]</p>

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

<p>This 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>

<p>A Netscape certificate sequence is an old Netscape-specific format that can be sometimes 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 was also used by Netscape certificate server.</p>

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

<dl>

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

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

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

<dt id="provider-name"><b>-provider</b> <i>name</i></dt>

<dt id="provider-path-path"><b>-provider-path</b> <i>path</i></dt>
