Could you give a couple of examples of critical information carried in
HTTP traffic that would become unavailable to such actors if they were
unable to decipher HTTP traffic? It seems reasonable to assume, for in-
stance, that they would be able through one way or another to find out
which IP address was associated with a given target at specific inter-
vals, and asking a couple of large corporations for all data they have
associated with the addresses during those intervals would likely yield
e.g. account identifiers, which could then be used to obtain even more
data. What could these actors want to know that would not be available
through such methods ten years from now?
