+The AUTH message informs the recipient that authentication is required to

+the recipient can sign with a private key. The recipient replies with an
+AUTH packet where type is SIGNATURE(2) and data is the signature. If the
+signature verification succeeds, the sender replies with a CONNECT packet.
+
+If the signature verification fails, the sender replies with a new AUTH

+Once the recipient has tried all its private keys, it can reply with an
