EXAMPLE
The code is decrypted by looking at the first letter of the chapter for each number, resulting in ERPERDJLWTEEOOGT. Decryption is performed using a columnar transposition cipher, termed a "Caesar Square" cipher in the book (this is unrelated to the Caesar cipher). The letters are arranged into a square:
ERPE
RDJL
WTEE
OOGT
and read from the top down.
ERWORDTOPJEGELET.
Add spaces and you get the plaintext, "Er wordt op je gelet" a reference to the NSA's monitoring systems.
