Request for Support with Pre-shared Key

[mauro-midolo]

I'm reaching out to request the implementation of pre-shared key support.
This addition would greatly benefit users requiring secure communication.

Could you consider integrating this feature into the project?

Thank you for your consideration.

This fork has already implemented the pre-shared key feature:
https://github.com/kienvu58/WireGuard-ESP32-Arduino

My fork, which is based on the above one, has also implemented some compiler error fixes, which I collected from other available forks ;)

@SpaceTeddy When I try to use your library with the provided code in examples, I get an error saying I need 14 arguments for the .begin instead of the 5 as provided in the example. Can you give a minimally working example of your library?

[SpaceTeddy]

well, I'dnt't compile the code below, but this is more and less my setup for initialisation.

//------------------------------[ WireGuard configuration ]----------------------
#include <WireGuard-ESP32.h>
#include "wireguardif.h"

static WireGuard wg;

IPAddress local_ip(192,168,0,100); // [Interface] Address, choose your local IP
char private_key[] = "your_private_key"; // [Interface] PrivateKey
char public_key[] = "your_public_key"; // [Peer] PublicKey
char preshared_key[] = "your_pre_shared_key"; // [Peer] PreSharedKey
char endpoint_address[] = "your_endpint_address"; // [Peer] Endpoint hostname or IP
int endpoint_port = 50614; // [Peer] Endpoint port

setup_wg(){

    if(!wg.is_initialized()){
        Serial.println("Initializing WG interface...");
        if( !wg.begin(
                local_ip,
                private_key,
                endpoint_address,
                public_key,
                endpoint_port,
                preshared_key) ) {
            Serial.println("Failed to initialize WG interface.");
            wg.end();
        }
    }
    else {
        Serial.println("Shutting down WG interface...");
        wg.end();
    }
    
    delay(500);
