A visit from Gus Andrews is always refreshing and invigorating as we explore some of the intellectual links in our mutual networks. So, last Wednesday, February 12, we talked, among other things, about the efforts of the organization where she works (she will have to provide the link…) to convince people around the world to use encryption to communicate in ways that, perhaps, governments and other cannot listen in. One of the problem is that it is hard to identify who are these people and, when members of plausible audiences are identified, convince them that this encryption is the solution to a problem many do not know they have. Some already use VPN (whatever that is, and however it works–it will advertise my ignorance here) and tell representatives of the institution that this works well enough for their purposes.
