🤷 What is VPN ?

A Virtual Private Network (VPN) allows users to send and receive data through shared or public networks as if their computing devices were directly connected to the private network. Thus, applications running on an end-system (PC, smartphone, etc.) over a VPN may benefit from individual network features, protection, and management. Encryption is a standard aspect of a VPN connection but not an intrinsic one.

📶 What is WireGuard❓

WireGuard is a straightforward yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general-purpose VPN for running on embedded interfaces and super computers alike, fit for many circumstances. Initially released for the Linux kernel, it is now cross-platform (Windows, macOS, BSD, iOS, Android) and widely deployable. It is currently under a massive development, but it already might be regarded as the most secure, most comfortable to use, and the simplest VPN solution in the industry.

⛳ Goals

  • robust and modern security by default
  • minimal config and critical management
  • fast, both low-latency and high-bandwidth
  • simple internals and small protocol surface area
  • simple CLI and seamless integration with system networking

🌲 Prerequisite

  • CentOS, Debian, Ubuntu, Arch, Fedora, Redhat, Raspbian, PopOS, Manjaro, Kali, Alpine, Mint, FreeBSD
  • Linux Kernel 3.1 or newer
  • You will need superuser access or a user account with sudo privilege.
  • Docker Kernel 5.6 or newer

📲 Installation

Instance Installation

Lets first use curl and save the file in /usr/local/bin/

curl https://raw.githubusercontent.com/complexorganizations/wireguard-manager/main/wireguard-manager.sh --create-dirs -o /usr/local/bin/wireguard-manager.sh

Then let's make the script user executable (Optional)

chmod +x /usr/local/bin/wireguard-manager.sh

It's finally time to execute the script

bash /usr/local/bin/wireguard-manager.sh

In your /etc/wireguard/clients directory, you will have .conf files. These are the peer configuration files. Download them from your WireGuard Interface and connect using your favorite WireGuard Peer.
