Post-quantum VPN. Understanding quantum computers and installing OpenVPN to protect them against future threats

Quantum computers have been widely discussed since the 1980s. Even though very few people have dealt with them by now, such devices steadily become a harsh reality threatening traditional cryptography. In response to this threat, computer engineers have developed post-quantum encryption algorithms. In this article, I will show how these algorithms are applied in OpenVPN and will give an overview of the current situation in the world of quantum technologies.
