Rossi: How’d you crack it? Reid: I profiled the author. Cortland Ryan was on death row with several high ranking members of the Aryans brotherhood. JJ: He got the code from the Aryans? Reid: Either that or he read a lot of sixteenth century literature. The Aryans liked to use a cipher based on a four hundred year old code written by Sir Francis Bacon. Morgan: So it’s a binary code. Reid: Yeah. Bacon used a twenty one letter alphabet. This one is twenty four. Each letter is assigned a bit-string of five binary digits. This combination yields thirty two possible encodings. Normally, you’d use a computer to run all these combinations, but it was quicker just to do it long hand until I found the right one.
