OpenVPN

OpenVPN is a Virtual private network protocol that is open-source. This means the source code is openly available for anyone to access and develop. It creates secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities.

An active community has formed around the OpenVPN project, which has kept it up-to-date and provided regular security audits to ensure it’s viability.

It is particularly known for its security and privacy as well as its adjustability.

OpenVPN typically works on any port and has five encryption algorithms to such as SSL, IPSec or SSH. AES 256-bit encryption is the best security and privacy as it is essentially unbreakable. A TCP 443 port will make a connection similar to an https connection. It is essentially a secure connection which can help prevent website blocking and bypass censorship.

For greater speed, it is recommended to use UDP ports, using the default, Blowfish-128 cipher. This isn’t the absolute highest level of security, but for most people, it will suffice and will operate significantly faster than AES 256 on TCP.
