<title>Generating SSL/TLS certificates for SIP agents and proxies</title>
</head>
<body>
<h1>Generating SSL/TLS certificates for SIP agents and proxies</h1>
<h2>Prerequisites</h2>
The openssl v0.96 or higher must be installed to create the certificates.

<h2>To generate the random seed file</h2>
<strong><pre>$ tport_rand tls_seed.dat
</pre>
</strong>

<h2>To generate the root authority certificate</h2>
<strong><pre>
$ make_root_cert.pl \
     -cn &lt;root common name&gt;\
     -dns &lt;comma separated list of root dns names&gt;\
    [-prefix &lt;prefix for the generated files&gt; (default root)]\
    [-rand &lt;random seed file&gt; (default tls_seed.dat)]</pre></strong>

This command will generate files <strong>&lt;prefix&gt;key.pem</strong> (root private key), 
<strong>&lt;prefix&gt;cert.pem</strong> (root certificate) and <strong>&lt;prefix&gt;.pem</strong> (combination
of the key and the certificate). The latter file will be used to sign the node certificates.

<h2>To generate a certificate for a single node (user agent or proxy)</h2>
<strong><pre>
$ make_node_cert.pl \
     -cn &lt;node common name&gt;\
     -dns &lt;comma separated list of node dns names&gt;\
    [-ca &lt;cafile&gt; (default root.pem)]\
    [-prefix &lt;prefix for the generated files&gt; (default agent)]\
    [-rand &lt;random seed file&gt; (default tls_seed.dat)]
</pre></strong>
This command will generate files <strong>&lt;prefix&gt;key.pem </strong> (node private key), 
<strong>&lt;prefix&gt;cert.pem</strong> (node certificate) and <strong>&lt;prefix&gt;.pem</strong> (combination
of the key and the certificate). The certificate has been signed with ca certificate
contained in <strong>&lt;cafile&gt;</strong>.

<h2>Installing the certificates to the nodes</h2>

<ol>

<li>Copy the root certificate file (<strong>rootcert.pem</strong> by default - <strong>not root.pem or rootkey.pem!</strong>), 
the combined node certificate+key file (<strong>agent.pem</strong>) and <strong>tls_seed.dat</strong> to the tls configuration
directory (default <strong>$HOME/.sip/auth</strong>)</li>

<li>Rename <strong>rootcert.pem</strong> as <strong>cafile.pem</strong></li>
</ol>
<p>
<strong>Note that files agent.pem and tls_seed.dat must be kept secret to
ensure secure connection</strong>  
</p>

</ol>
