OpenVPN is a free and open-source software application that implements virtual private network (VPN) techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange.
OpenVPN is designed to be easy to use and configure, and it is fully documented. It can run on any port, so it can be easily configured to run over non-standard port connections, such as HTTP or Secure Sockets Layer (SSL). OpenVPN can also use a static key for simple configurations or a PKI (public key infrastructure) for more complex configurations.
This VPN tool is highly flexible and can be configured to work in a variety of scenarios. It can be used to connect a remote client to a private network, such as a home or corporate network, or to connect two private networks together over the internet. It can also be used to provide secure remote access to a single computer or device. OpenVPN is often used in conjunction with other security measures, such as firewalls and intrusion detection systems, to provide a comprehensive security solution.
In summary, OpenVPN is a secure and flexible VPN solution that can be used to establish secure connections over the internet and protect data transmission. It is widely used in both personal and corporate settings to provide secure remote access and connect private networks together.
