bool "WireGuard secure VPN tunnel"
WireGuard is a secure, fast, and easy to use replacement for IPSec
that uses modern cryptography and clever networking tricks. It's
designed to be fairly general purpose and abstract enough to fit most
use cases, while at the same time remaining extremely simple to
configure. See www.wireguard.io for more info.
It's safe to say Y or M here, as the driver is very lightweight and
is only in use when an administrator chooses to add an interface.
bool "Debugging checks and verbose messages for WireGuard"
depends on WIREGUARD
This will write log messages for handshake and other events
that occur for a WireGuard interface. It will also perform some
extra validation checks and unit tests at various points. This is
only useful for debugging.
Say N here unless you know what you're doing.
bool "Enable parallel engine"
depends on SMP && WIREGUARD
This will allow WireGuard to utilize all CPU cores when encrypting
and decrypting packets.
It's safe to say Y here, and you probably should, as the performance
improvements are substantial.
