115 <h2>VPN connection via OpenVPN</h2>
116
117 <p>When working via wired communication channels (Internet), it is recommended to establish a secure data exchange channel between the client&rsquo;s equipment and the CENTO server using a <strong>VPN channel based on the OpenVPN protocol</strong>.</p>
118
119 <p>To implement an OpenVPN channel, the client must have a router that supports the OpenVPN protocol (supported by most modern routers).</p>
120
121 <h2>Connection files</h2>
122
123 <p>The following files are provided to the client for connection:</p>
124
125 <ul class="file-list">
126 <li><code>ca.crt</code> <span>Public certificate of the certification authority</span></li>
127 <li><code>client.crt</code> <span>Public client encryption certificate</span></li>
128 <li><code>client.key</code> <span>Private key for the client certificate</span></li>
129 <li><code>auth.cfg</code> <span>File containing the username and password</span></li>
130 <li><code>client.ovpn</code> <span>OpenVPN configuration file</span></li>
131 </ul>
132
133 <div class="note-info">
134 <div class="note-hd"><span>&#8505;</span> Security note</div>
135 <div class="note-body">The files <code>client.crt</code>, <code>client.key</code>, and <code>auth.cfg</code> are generated <strong>individually for each client</strong> to ensure connection security.</div>
