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."
