An OVPN file is a configuration file used by OpenVPN, a popular open-source virtual private network (VPN) system. It contains the settings and instructions needed for an OpenVPN client to connect to a specific VPN server. These settings include server addresses, port numbers, encryption algorithms, authentication methods (like usernames, passwords, or certificates), and other security parameters. The OVPN file essentially acts as a blueprint for establishing a secure and encrypted connection between your device and the VPN server. It allows users to easily import and configure their OpenVPN client without manually entering all the necessary settings. The file is typically a plain text file, making it relatively easy to inspect and modify, although caution should be exercised when editing to avoid compromising security. Using an OVPN file simplifies the process of connecting to a VPN, ensuring that the connection is properly configured and secure.
