![]() ![]() Generate a pre-shared key for each peer pair using the following command (make sure to use umask 0077 for this as well):Ĭurrently, WireGuard does not support comments or attaching human-memorable names to keys. For example, three interconnected peers, A, B, and, C will need three separate pre-shared keys, one for each peer pair. A pre-shared key should be generated for each peer pair and should not be reused. One can also generate a pre-shared key to add an additional layer of symmetric-key cryptography to be mixed into the already existing public-key cryptography, for post-quantum resistance. $ wg genkey | (umask 0077 & tee peer_A.key) | wg pubkey > peer_A.pub The above alters the umask temporarily within a sub-shell to ensure that access (read/write permissions) is restricted to the owner. Note: It is recommended to only allow reading and writing access for the owner. wg_tool - Tool to manage wireguard configs for server and users.Qomui - OpenVPN GUI with advanced features and support for multiple providers.See #Persistent configuration for details. Install the wireguard-tools package for userspace utilities.Īlternatively, various network managers provide support for WireGuard, provided that peer keys are available. WireGuard has been included in the Linux kernel since late 2019. Initially released for the Linux kernel, it is now cross-platform (Windows, macOS, BSD, iOS, Android) and widely deployable.Ī rough introduction to the main concepts used in this article can be found on WireGuard's project homepage. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. It intends to be considerably more performant than OpenVPN. It aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache. WireGuard is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography.
