WireGuard offers a free and open-source VPN protocol known for its speed, simplicity, and robust security. It’s a direct communication VPN protocol that employs encryption to safeguard data sent between a client and a server. Due to its compact code base and minimal overhead, WireGuard is especially effective for embedded devices like routers and smartphones.
For authentication and establishing secure connections, WireGuard relies on public key cryptography. Every user gets a pair of public and private keys. Data sent to the client is encrypted by the server using the client’s public key. The client then decrypts the received data using its private key. ChaCha20, a highly secure and efficient encryption algorithm, is used by WireGuard for this encryption process.
If you’re looking to deploy WireGuard VPN on a VPS, it can be streamlined using the WireGuard installer script. This guide will walk you through the steps to get a WireGuard VPN up and running on a Virtual Private Server with ease: https://coin.host/blog/how-to-set-up-a-private-wireguard-vpn-server-on-a-vps
