It is truely mind-boggling how Dan Brown can get away with putting so many factual errors about cryptography and computers into a single book. Doesn't he have anybody proofread his manuscripts? It is also surprising that a so highly praised writer can write so badly.

In "Digital Fortress" we enter a universe where:

* A 64-bit code requires 64 characters to type. (Fact: 64 bits can be easily typed with 16 characters or less.)

* Public Key Cryptography requires the exchange of a secret passkey. (Fact...more

There's a reason why everyone talks about The DaVinci Code and not about this book. I have no idea what that reason would be, because I thought Angels & Demons was mediocre so I never bothered to read the The DaVinci Code. Anyway, I was bored and a copy of this was sitting at the library for a quarter and I thought "WTF, mate, I'll give it a go."

The first page of chapter 1 starts with Susan Fletcher waking from a romantic dream to the ringing of the telephone:

"Susan, it's David. Did I wake y...more

I work in the Information Technology field so relating to this book was easy for me. I don’t know anything about NSA (National Security Agency) and how they operate but I know stuff like encryption, algorithm, anagram, computer virus, code-breaking, etc. So, this book glued me from start to finish. My officemate has been telling me that this is his favorite Dan Brown book. He said that since I’ve read all his 4 other novels, The Da Vinci Code, Angels and Demons, Deception Point (all 3 stars, i.e...more

هل أنت مبرمج ؟
إذاً ، لا تفوت قراءة هذه الرواية :)
عامة الناس سوف يستمتعون بقراءتها ، وأنتَ وحدك من سوف يفهم ما وراء سطورها
وشيفراتها ، سوف تشعر بأنها تعنيك أنتَ وحدكـ .

أذهلتني هذه الرواية ، عشتُها لحظةً بلحظة ، حرفاً بحرف ، كنتُ أستيقظ باكرًا لأبدأ قراءتها حتَّى تتعب عيناي ، مختلفةً هذه الحكاية عن كل ما قرأتُه وسوف أقرأه !.

سؤالين يتبادران إلى ذهني الآن ، أولهما / ما هو تخصص دان براون ؟ التاريخ ؟ علم الأديان ؟ أم البرمجة :)

السؤال الآخر / لماذا النساء في روايات بروان مثالياتٌ إلى حدٍّ غبي ؟

I learned that Dan Brown is a bad writer and I will never read any of his other books. I also am upset at my friend for recommending me this book.


In short, the book is a bad novel, and a very bad novel if you know anything about math / cryptography.
Not only the technical errors were appalling, but the writing style itself is mediocre.


WARNING: spoiler here.

There is a scene where the heads of NSA along with some of the smartest people on Earth were trying to solve a riddle left by the bad guy as a

When I first read the DaVinci Code a couple of years back, I admit that it wasn't all that bad (at least for the first two-thirds or so), but in light of its content I found it significantly overrated... Upon reading this book, however, I am outright insulted that this man's success is inspiring documentaries on the History Channel...

I had the unfortunate luck to inherit this along with a box of other (and thankfully much more redeeming) books when a good friend of mine was leaving Japan. After...more

I'm not sure what to believe after reading this book. I've always liked Dan Brown's books because he writes so realistically, using big words to belittle readers about how little they know.
Or so I thought.
After reading this book, I did a little snooping of my own (OK, those were big words too, I just used Google) and realised that most of the technology, computers and cool machinery did not exist. In fact, Goodreads was an excellent source of information of unhappy reviewers tearing down this bo...more

What would happen if every nation and person in the would, with a computer, could access every top secret file of the government? This is what Susan Fletcher and David Becker have to prevent in Digital Fortress by Dan Brown. With a lot of action and suspense Digital Fortress is a book for anyone who likes action.

Dan Brown wrote many other action novels. I have read all of them and this novel is just as good of a read as the rest. This novel is written in the same style as all the others. Leaving...more

No matter what people want to say about Dan Brown or his books or hatred towards him you got to admire the fact that what he brings to the table no one else does.

This was the book which brought me to the beautiful world of books. Before reading this book I though reading was a bit cissy and a waste of time since everything is fictional, why not better read some spiritual/self help and knowledge books. After reading this book everything changed, I started to read more and more fiction and today b...more

Oh Dan Brown, how I love to hate you. It seems a universal truth that when you have run out of all of the books to read that you’ve brought with you, it is impossible to find decent reading material wherever you are.

Shamefully, I’ve actually read most of his books. I read Angels and Demons because someone recommended it to me. Though I found his writing to be extraordinarily poor, I found the story to be engaging enough to overlook that fact. I didn’t guess the ending, and it posited some fasci...more

Here’s the problem: Digital Fortress has a good plot, but it’s filled with weak characters. I really liked the plot. A disgruntled NSA employee develops an unbreakable encryption program (the Digital Fortress) and threatens to give both the encryption program and the key (which is buried in the program) away on the Internet. If the bad guys gain access to the key, they will be able to communicate without fear of the NSA decrypting their messages. This throws the NSA into a panic – as it should –...more

Avevo ragione a pensare che leggendo che questo libro mi sarei fatta due sane risate. Infatti, a mio modesto avviso, Dan Brown è uno scrittore umoristico travestito da autore di thriller.

A dire il vero, di risate me ne sono fatta ben più di due, perché i protagonisti hanno un “culo” che neanche i miracolati di Lourdes possono vantare. Sempre sull’orlo di un baratro, ne escono fuori illesi in virtù non tanto del loro presunto altissimo quoziente intellettivo, che in realtà deve essere assai pross...more

Based upon how very little I'd heard about Dan Brown's two non-Robert Langdon books, I went into this one with very low expectations. However, Digital Fortress is a fairly well-written and entertaining novel. The main storyline is based upon a hush-hush operation within the NSA to obtain and or destroy the only existing copies of a pass-key that, if made public, could enable the use of an encryption program that would create coded messages that would be entirely unbreakable thereby rendering the...more

رسميا .. أصبح دان براون هو الروائى المفضل لى
رواية فيها رومانسية . خطر . إثارة . و مغامرة رائعة كعادته
و الأشخاص بتتكشف بطرق فظيعة .. و كنت بحس بالتوتر بيزيد مع كل صفحة
هى عبارة عن مركز الأمن القومى فى أمريكا عندما تتم محاولات اختراقه

Officially Dan brown is my favorite author now!
the novel has got it all, danger, romance, excitement, and a great adventure as always
the revealing of each character's role & plot is amazing and the tension ge...more

My book group chose this book and I will never forgive them.

I’ve never read anything by Dan Brown. He doesn’t write my type of fiction, so while I was aware that he’s a huge success, I never bothered to pick any of his books up because I knew I wouldn’t be interested.

What I didn’t know is how much of a shit writer he is.

I’m sure he cries into a giant pile of money every single time someone tells him that.



Digital Fortress is about the government and secrecy. Susan Fletcher works for a super top s...more

Reading Dan Brown books is a bit like watching porn. Mildly enjoyable at the time, but not really something you'd like your friends or family to know about.

Digital Fortress starts as it means to go on, with two-dimensional characters in a whirlwind of mystery and action. The cast never evolves beyond cardboard cut-out level, but the plot does pick up through various levels of incredulity and intrigue to a climax that ends up shallow and disappointing, leaving the reader feeling cheap and cheated...more

وأخيرا، أنهيت قراءة هذا الكتاب

لقد كان من الجيد أن نأخذ إستراحة من روبرت لانغدون بطل ثلاثية دان براون الأشهر "شيفرة دافنشي" و"ملائكة وشياطين" و"الرمز المفقود"، ففي هذه الرواية أبطال يختلفون في الإهتمامات والمقاصد

*A Typical American Novel, a typical American end.

الرواية تعبر إلى حد كبير عن الهوس الأمريكي بالتكنولوجيا واستخدامها في كل ما يخدم الإستخبارات الأمريكية والتجسس، وتتناول بشكل ما حرية تداول المعلومات وحرية المراسلات. الرواية مثيرة وفيها تقلبات مفاجئة، فقد تغيرت قناعاتي في أكثر من مرة في تو...more

Here's the thing with Dan Brown's work, once you read one, you read them ALL!

It was surprisingly my first book of Dan brown. Cryptography was always an interesting subject for me and always had a kind of passion towards the way it encrypt and decrypt things. I am the one who use cryptic words even in the conversation and I know exactly why I loved this book so much now. Story was changing very fast in last few hours and terribly stressed me when the worm was about to hit their main database. I liked susan :) , liked the plot and the way its carried out :)

I don't even remember what this one is about. There's a CIA computer technician, and all I can remember about her is the scene where a security guard is ogling her sweet, sweet ass and wondering in bafflement how a woman with a 192 IQ could be so damn fuckable. Also, I'm pretty sure she saves the world with computers, but we're not supposed to care because she does it while her shirt is partially unbuttoned. She may have gotten wet at some point, too.

Digital Fortress is a mysterious, intriguing book by Dan Brown. Dan Brown is a widely known author, who has written The Da Vinci Code and Angels and Demons. This book is about a woman named Susan Fletcher, who works for the National Security Agency (NSA). After five years of work, the NSA invented the TRANSLTR, which could break any code known to man. TRANSLTR is faced with a code that it cannot break, and when the NSA calls it head cryptographer, Susan Fletcher, she uncovers that the NSA is bei...more

You know how some days you just feel like eating candy? And then more candy, maybe topped off with ice cream, cookies, cake? Some days that is okay. Until you get to about eight o'clock at night, and your body has reached a point that is beyond satiation. And then you think to yourself, just one last cookie. Your stomach is telling you don't do it. It's gurgling and protesting the hours of abuse it has already taken, but you keep thinking about how good that cookie is going to taste. So you do i...more

Dan Brown has made his mark in the world of fiction by combining complex mental puzzles with action-filled adventure and romance. His thriller, "Digital Fortress" has all of these elements, and it is an exhilarating novel that raises timely and thought-provoking questions.

A covert agency, known as NSA (jokingly, "No Such Agency"), has a multi-billion dollar secret device known as TRANSLTR that can decrypt any code. It is used to eavesdrop on encrypted email communications worldwide; the data th...more

After reading Dan Browns Da Vinci Code and being completely immersed and engrossed into every chapter, I was a bit dissapointed reading Dan Browns Digital Fortress. It starts out when the NSA code breaking machine (called TRANSLTER) finds a new and complex code, named Digital Fortress, that it cannot break. Commander Trevor Strathmore calls in Susan Fletcher, their head cryptographer to help crack it. She discovers that it was written by Ensei Tankado, a former NSA employee who was displeased wi...more
Benjamin Duffy
If the roundly reviled The Da Vinci Code and Angels and Demons are examples of Dan Brown at his most polished, you can only imagine how bad he was during his early career.

Actually, you can imagine, or you can read Digital Fortress and find out for yourself. But I don't recommend it. Where the Langdon books spill their secrets two acts too soon to anyone with a basic knowledge of French, or of Latin roots, Digital Fortress boasts a simplistic play on words that crumbles, fortune cookie-like, to a...more

Have you heard of the NSA? I think these days, a lot of people know the NSA but apparently, there was a point in time when no one knew what the NSA was. Oh, NSA = National Security Agency. I've been there. Well, not there exactly, cuz it was after 9/11 = mad security. I was at the Cryptology Museum right next door.

Anywho, this Dan Brown thriller, post Da Vinci Code fame, follows much the same style and basic plot structure as Angels & Demons and The Da Vinci Code. You can almost see the plot...more

Definitely a fast-paced book that was breathtaking at times which took me into the world of of cyberism and national intelligence. What I love about this book was that the heroine, Susan, was a female. Not only that, but she was one of the important asset to breaking the code.

As we may know or realize (or not), our government has many top secret infos and files with top-of-the-line technologies, firewalls, and so on. Imagine when someone was blackmailing the agency and was on the verge of exposi...more

Dan Brown CAN actually write. Angels and Demons was inventive, well-paced and exciting. The DaVinci Code was really just Angels and Demons repackaged, but it was still a good summer read.

This book, however, is complete crap. I have read it so you don't have to. Avoid at all costs.
