  1. Two reasons why this isn't big by Sheepdot · · Score: 5

    There are two big problems I have with this "new" technology.

    1) It isn't anywhere near feasible for common use, nor cheap enough.

    2) We already have "pretty good privacy". It's not the best, but it is sufficient and now we need to work on the next big step: securing both ends.

    I think we've pretty much covered the encryption news to death and left out some of the big stuff, the compromising of a machine on either end of the communication.

    What good does a secure method of communication do when the website you are dealing with stores your credit card info in clear text databases on machines 4 different crackers have access too?

    What good is securing a transmission with a customer when their Windows box is already compromised by a Subseven server?

    I guess what my biggest beef with secure communication overkill like this is that we've already determined it is possible to secure a transmission. We haven't determined how to properly secure both the client and the server.
