| 4 | When working via wired communication channels (using the Internet), to establish a secure data exchange channel between the client's equipment and the CENTO server, it is recommended to use a secure VPN channel based on the OpenVPN protocol. | ||
| 5 | |||
| 6 | To implement a VPN channel based on the OpenVPN protocol, the client must have a router that supports the OpenVPN protocol (supported by most modern routers). | ||
| 7 | |||
| 8 | The following files are provided to the client for connection: | ||
| 9 | |||
| 10 | * ca.crt - public certificate of the certification authority | ||
| 11 | * client.crt - public client encryption certificate | ||
| 12 | * client.key - private key for the client certificate | ||
| 13 | * auth.cfg - file containing the username and password | ||
| 14 | * client.ovpn - OpenVPN configuration file | ||
| 15 | |||
| 16 | To ensure security, the client.crt, client.key, and auth.cfg files are created individually for each client. |
