### HMAC Message Authentication ### HMAC Message Authentication
Message authentication is a user-configurable feature that's enabled if an authentication key is provided. Please *DO NOT USE A PASSWORD THAT YOU ACTUALLY USE FOR ANYTHING ELSE!* Do note that facility authentication keys are not securely stored, so anyone with access to the server's file system or the computer can view them. Note, computing hashes and serializing the messages takes some additional processing time, though it appears to be worst case in the 10s of milliseconds. Coordinator status packets are the largest, so those take the longest, giving those 10-20ms hash/verify times.
