# wg set wg0 listen-port 51871 private-key /path/to/peer_A.key In this example peer A will listen on UDP port 51871 and will accept connection from peer B and C.

Reason: These examples use the pre-shared keys which were introduced as optional in #Key generation. Manual setup is accomplished by using ip(8) and wg(8). One solution is to generate a public key that contains some familiar characters (perhaps the first few letters of the owner's name or of the hostname etc.), wireguard-vanity-address AUR does this. This makes identifying the key's owner difficult particularly when multiple keys are in use. Generate a pre-shared key for each peer pair using the following command: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.
