You can get yourself a vanity key using https://github.com/AlexanderYastrebov/wireguard-vanity-key tool:

   % wireguard-vanity-key -prefix=NAS/
   private                                      public                                       attempts   duration   attempts/s

While it's cool, something about vanity keys in general stroke me the wrong way. I feel like in principle you should never use a very short part of a public key for ocular identification, and it attempts to solve something that should be solved outside of wireguard, i.e. the "friendly naming" of public keys.
