WireGuard protocol implementation in Dlang

This project implements the WireGuard protocol in D.

The main part of the implementation is in proto.d. Other part of the protocol include a Temps Atomique International (TAI) struct, a Blake2s implementation, some crypto primitives, and a key abstraction.

The library is meant to be used via its library subconfiguration:

"dependencies": {
    "wireguard": "~>x.y.z"
},
"subConfigurations": {
    "wireguard": "library"
}

Client

This library also includes a simple client under its application configuration. As this requires CAP_NET_ADMIN, you might need to run it as root.
