Cryptogram or Claptrap?

Bruce Schneier, a computer security expert, has an intriguing posting in his blog. It purports to be a cryptogram that was found near the body of a suicide who had just murdered his wife and stepson. While there was some doubt at first as to whether the cryptogram is genuine, it appears that it may well be. The comments on Schneier’s blog entry are also worth reading. The most plausible explanation is currently that (assuming the cryptogram is genuine) it represents a cheat sheet for a series of computer passwords.
