Nothing about this discussion is about the security of the transmission. I'm sure your points would be interesting, if that's what we were discussing.

You've also obviously completely failed to grasp the nature of individual private keys. I suggest again "The Code Book", as an entertaining history of cryptography, and a layman's non-technical introduction to public key cryptography.

For myself, however, the topic is over. I appreciated Kovid's agreement and understanding, Peter's cogent comment on the mindset of publishers, and the posters who pointed out examples of this system already in practice.

But feel free to continue to talk about how it doesn't prevent piracy, and how once "the key" is "cracked" the whole system is broken.
