Thank you, that was a very informative explanation.

BTW, can't Mallory (e.g. NSA++) inject fake DNS responses (QUANTUMLEAP, or whatever it is called) to the ACME server to falsely "prove" it is the owner of Bob's domain, and then get certificates for his domain? Is dns txt records as authentication good enough?
