Aside from thousands of possible encoding schemes that could be used to embed a "plain-text" message, one must consider that the text could easily be obscured beforehand by some combination of compression or otherwise "weak" encryption. The combinations and variations are staggering, and if you don't hit upon the right one, you see nothing out of the ordinary. As much as I oppose "crypto-banning" in general, I find the statement "The researchers discuss, and dismiss, the possibility that strong passwords were being used" to be patently self-serving. ____tony____ At 10:54 PM 9/21/01 -0700, you wrote: >Research slaps crypto-banning Feds > >By Andrew Orlowski in San Francisco > >Posted: 22/09/2001 at 01:03 GMT > >While America's own fundamentalists - led by US Attorney General John >Ashcroft - prepare the most draconian assault on Americans' civil >liberties since the second world war, their very own causus beli seems >to be vanishing. > >The enormous increase in surveillance has been justified by claims that >terrorists are using cryptography, and in particular steganography: the >art of hiding information.
