Dato che oggi discutevamo su quale fosse un possibile scenario di utilizzo di HMAC, riporto un esempio da Wikipedia EN.
A pizza restaurant that suffers from attackers that place bogus Internet orders may insist that all its customers deposit a secret key with the restaurant. Along with an order, a customer must supply the order's HMAC digest, computed using the customer's secret key. The restaurant, knowing the customer's secret key, can then verify that the order originated from the stated customer and has not been tampered with. _________________ Let the future tell the truth and evaluate each one according to his work and accomplishments.
