What is OpenVPN?
OpenVPN is a virtual private network type, which provides strong point-to-point or site-to-site connections encryption. The current technology is one of the most demanded and widely used by both organizations and private clients. OpenVPN is open source protocol, which can be both upgraded and modified according to user’s needs.
OpenVPN protocol features
OpenVPN is one of the most secure and safe protocols. This technology is deemed one of the best VPN options. The technology’s features are the following:
- 256-bit encryption usage within OpenSSL technology in order to protect data from hacking attempts.
- Support for L2TP, PPTP and IPSec technologies. TLS and SSL usage as the basis for own information encryption protocol.
- Ability to both install and configure additional plugins and scripts in order to improve authentication technology, speed up the encryption process.
- Private network setup support, the ability to connect to remote servers, installed outside OpenVPN's range.
- Tls-auth technology appliance. Reliable protection against DoS, port scanning and overflow. OpenVPN operation in user space instead of the kernel.
Low encryption and information transfer speed is one of the main protocol disadvantages. But this feature is not an issue for broadband communication channels. Complexity to set up OpenVPN to Windows and other operating systems is one more drawback. The current technology provides a great chance to easily avoid blocking at almost any firewall level.
