Digital Fortress: A Thriller by Dan Brown

My Rating: Five Stars 

Having already read “The Davinci Code” and Angels & Demons” I decided to give “Digital Fortress” a read. Mr. Brown does not disappoint… this book was just as fast-paced and full of twists as his other books. I couldn’t put it down! I work with computers so the tech-speak made the book more interesting to me. Others may be put off by that but he explains everything as you go so non-techies can get it too. I think I actually learned some things about number theory and cryptography from this book! The book is about the National Security Agency (NSA) and basically their search for dominance in the encryption algorithm market – so they can snoop everyone’s’ email (among other things). In this pursuit things don’t go quite as planned and the underlying love story adds another level of intrigue to the whole story. The characters are well written and I felt like I knew the main character, Susan Fletcher the NSA’s lead cryptographer and her fiancée, David by the end. I don’t want to spoil the story for those of you that haven’t read it so I’ll stop there. Once again Mr. Brown’s writing is enthralling I read this straight through in a day!

I read some of the other comments about this book on and I just want to say this is FICTION and is allowed to be full of government conspiracy theories and as one-sided as Mr. Brown sees fit. I really don’t think he was trying to make an anti-political statement; but considering the recent NON-FICTION news related to the NSA intercepting all of our phone logs recently I think the book may have a modicum of truth.

  1. There is a code on the last page…


    (If you want the answer go read the next comment.)

  2. I finally figured out the code in the back of the book! It took me way too long and it was because I missed the obvious.



    The highest number in the code is 128.
    There are 128 chapters in the book.
    There are 16 letters in the code.
    16 has a perfect square of 4.
    The method for deciphering is explained in the book.

    Answer is on the next comment (I promise!)

  3. Cracking the code…

    The numbers represent chapters in the book.
    Use the first letter in the chapter.
    The method is Caesar’s Square.

    Chapter First Letter
    128 w
    10 e
    93 c
    85 g
    10 e
    128 w
    98 h
    112 y
    6 a
    6 a
    25 i
    126 o
    39 r
    1 t
    68 n
    78 u

    Rearrange the letters into a 4×4 square.
    Read top to bottom, left to right.

    w e c g
    e w h y
    a a i o
    r t n u
