OpenVPN: What Is It and How to Use It

The privacy protection industry has boomed in the past few years, as many realized that anonymity shouldn’t be reserved for those who engage in shady activities.

VPNs have been around for over two decades, but they have dramatically improved since their creation. Initially, the VPN started as a way to facilitate secure, private communication and file transfer between companies. It was not intended for the general public.

The first VPN was based on Point-to-Point Tunneling Protocol (PPTP), a protocol that is now obsolete due to its numerous security vulnerabilities. In time, more protocols were developed to address the need for a stabler, faster, and more secure connection.

What is OpenVPN

OpenVPN, one of the best-known VPN protocols, was first released for public use in 2001 and is still a strong contender, even when paired against newer technology.

Arguably, OpenVPN strikes a perfect balance between speed and security, which could explain why most reputable VPN providers implement it within their products. Some of the most significant features that make OpenVPN an ideal choice include:

• SSL/TLS protocol for key exchange
• Up to 256-bit encryption support through the OpenSSL library
• 2048-bit RSA authentication
• 160-bit SHA1 hashing
• TLS protocol to encrypt VPN traffic and manage key exchange
• udp and TCP support
• Full IPv6 support
• high compatibility with numerous device type and operating system
• Supports traffic obfuscation to bypass geographical restrictions
• Perfect Forward Secrecy support that facilitates the creation of new random keys during each data transmission

As its name suggests, OpenVPN is open source. The project is entirely supported by the community, has several developers, and receives constant updates to ensure top-notch security, speed and stability.

How to use openvpn

Despite its attractive features, casual users often see OpenVPN as a complicated protocol. Unlike other protocols, OpenVPN lacks a graphical user interface (GUI); instead, it can be set up manually by editing configuration files.

Misconfiguration is expose could expose the connection to several security risk . wrongfully believe that the connection is secure could lead user to take unnecessary risk online and jeopardize their privacy and security without their knowledge .

Furthermore, an OVPN connection lacks advanced VPN features, including kill switch, split tunneling, DNS leak protection, ad-blocking and tracker prevention.
