200-Year-Old Cipher Finally Cracked
Attila Dimedici writes "A code expert just cracked a code used by a friend of Thomas Jefferson in a letter written to Jefferson some 200 years ago. This code is fairly easy to crack using a computer, but extremely difficult without one. I think it would have been much harder if the author had not included an indication as to what code algorithm he used in the letter accompanying the coded message."
the Voynich manuscript is a much more compelling and difficult mystery.
The elusive Zodiac Killer's 360 character cipher was never cracked, either, and it's been decades since he mailed it to newspapers. That cipher also seems a bit grid-like, with spacing made deliberately in rows. I wonder if this method would help, at least in part, in cracking it?
If anything, would be nice to see something come up to ascertain his identity, and if alive, put him behind bars.
