Factual error: The whole book is about a computer breaking a very strong code, and that for every code a large enough computer can be built to break it. That's simply not true: The "one time pad" cannot be broken by brute force, only by traditional stealing of the key.
Trivia: The cipher that Brown calls a "Caesar box cipher" is actually called a columnar transposition cipher. Julius Caesar did really invent ciphers, but the only one whose description has survived - and which to this day is called the "Caesar cipher" - is much simpler than the columnar transposition.
