Please add authorization to the SOCKS5 Proxy

Please add authentication to the SOCKS5 Proxy so that third-party applications cannot determine the address of the remote server.

What I mean is that in proxy-only mode, some applications may be able to connect to the proxy without a password and find out my server's IP address.
One guy from 4pda made a modification of your version of Nekobox (last version) and published the patches. Please take a look; you might find something useful to borrow. It includes proxy authentication.
Also, please pay attention to this important patch:

• Ported the PersistentKeepalive fix for older kernels (4.17 and earlier) from wireguard-android
