            "description": "The use of HMAC to hash the response from the server can also be used to thwart reflection. The server responds by returning its own challenge as well as hashing the client's challenge, its own challenge and the pre-shared secret. Requiring the client to respond with the HMAC of the two challenges ensures that only the possessor of a valid pre-shared secret can successfully hash in the two values.",
