I have some dogs and my old postman had a problem with it, to the point of actually attacking one of my dogs and chasing it around my yard. He got away with it by claiming my dog attacked him. I moved my mailbox out to the street (there is a 3ft easement that is considered a public/utility way) and talked to the local postmaster general. It was made clear that if he stepped into my yard I would press trespass. Both the postmaster and the local police agreed that was legal.

If it were, analysts would start off by encrypting the message again. It has been a while since I've read on this, too, so please correct me if I'm wrong, but what is important for multiple encryption is whether or not the cypher in question is a group (as in closed under composition). DES, for example, is not, so multiple DES cycles is not equivalent to single DES. Again, I probably shouldn't be talking about this, as I haven't refreshed my memory on it in a while. -j -- Jamie Lawrence jal(a)jal.org "The current pursuit of American supremacy reminds me of the the boom-bust process, or a stock market bubble.

Which would lead to the question of why would (Nike) not just have "(Nike) News" - a newspaper or similar entity, completely hand-assed. The distinction between the press and non-press would appear to be difficult to define in anything like legally binding terms anyhow. (Not that I'd know.) FB`

This is why double >and triple DES are stronger than single DES. Also if you don't trust a given algorithm then chaining it doesn't help. You can also increase robustness by adding noise, at a cost of bandwith, see US patent 6,351,539, which both chains dissimilar ciphers and adds noise (doubling bandwidth requirements).

He's actually relevent to this list, viz.: There exists a "King Crimson collector's club" wherein, for $$ up front, you receive CDs in the future which are put together from concert tapes, which he judges to be not worth releasing otherwise. (Some have *awful* audio quality but of interest to fans, some are as high quality as modern studio work but are live performances.) This is different from the Foobar Record Club where the albums already exist. The KCCC is based entirely on reputation. He also leaves the copyrights with the artists, rather than publishers, and has written several rants on this :-) "Contrary to common practice within the music and record industry, both artists own the copyright in their work. " in his own words. (Albeit this is a mere biz model choice, and all are free to implement their own policies, although RF frames it morally.)
