3. Key Components of a WireGuard Server

Understanding the key components of a WireGuard server is crucial for setting it up and maintaining it effectively. Here are the main elements:

WireGuard Interface: WireGuard operates by creating a network interface, such as wg0, similar to eth0 or wlan0. This interface is configured using standard networking utilities like ifconfig(8) or ip-address(8) for IP addresses and route(8) or ip-route(8) for routing. The wg(8) tool is used to manage WireGuard-specific aspects of the interface.
Private and Public Keys: Each WireGuard interface requires a private key, which is kept secret, and a public key, which is shared with peers. These keys are used for encrypting and authenticating data. The exchange of public keys is similar to how SSH keys are exchanged.
Peers: Peers are the other endpoints (clients or other servers) that connect to the WireGuard server. Each peer is identified by its public key and associated with a list of allowed IP addresses.
AllowedIPs: This is a list of IP addresses that a peer is allowed to use within the tunnel. When the WireGuard server receives a packet from a peer, it checks if the source IP address is in the peer’s AllowedIPs list. If not, the packet is dropped. Similarly, when the server sends a packet to a peer, it uses the AllowedIPs list to determine which peer to send the packet to.
Endpoint: The endpoint is the IP address and port number of the peer. The WireGuard server uses this information to send encrypted packets to the peer. Clients typically have an initial endpoint configured for the server, while the server learns the endpoints of its peers by examining the source of authenticated data.
Cryptokey Routing: WireGuard uses a concept called Cryptokey Routing, which associates public keys with a list of tunnel IP addresses. This mechanism ensures that only authorized peers can send and receive traffic through the tunnel.
Encryption Protocols: WireGuard uses state-of-the-art cryptography, including the Noise protocol framework, Curve25519, ChaCha20, Poly1305, BLAKE2, SipHash24, and HKDF. These protocols provide privacy, authenticity, and perfect forward secrecy.
