Hendrickson delves deep into the history, statutes and case law behind the Code to reveal its startling and liberating secrets; and unless you live in a cave, you need to know what he has uncovered. Once you've finished Cracking the Code, the tax laws will never mean the same thing to you, or your bank account, again! Cracking The Code soon became a popular byword within both state and federal prison paralegal circles. The books were filled with 'advanced' information like none that had ever existed before. A totally new 'concept' of legal process like had never existed before. Only, Cracking The Code was somewhat complicated for the average Joe.

The Code Book is like geek porn. Explanations of the theories behind cryptography are woven together with anecdotes of times when code-making or code-breaking was integral to historical events. Singh strikes an excellent balance with this book. The clarity of his writing makes the explanations of the mathematics of cryptography very straightforward without dumbing them down, and the historical connections are always fascinating.

Coming on 20 years after the book was written, it’s still quite awesome despite all our subsequent advances in cryptography.
Or rather, I should say, we’re still living in the same world already transformed by pretty good encryption. The methods for breaking the security still falls in the same category as usual: interception. Of course, the means of interception has gotten amazingly good and creative as hell, but that isn’t the primary scope of this book.

I haven’t had this much gleeful delight in a book in a long time. This book is pure fun. It’s not fast reading necessarily, and requires some active engagement to keep up, but man, it is a blast. If you read a lot of spy books as a child, or if you’re secretly jealous when there’s a cipher to be solved in a TV or movie plot and a character says,“Yeah, I can totally crack this if I have a few hours, let me get to work,” you’re going to love this.

This is a *must* read before reading Cryptonomicon. Or maybe after, like I did.
If you at all feel uncomfortable in your knowledge of one time pad cyphers, public/private keys, or the importance of really good cryptography for average folks, please read this book! It's sadly a bit out of date, but Singh does such a brilliant job of methodically building up the complexity in cyphers though history, that you will inevitably learn a ton.

I really enjoyed The Code Book. The explanations were well-done, and the history lessons amazed me, which is odd because I'm not a history fan. I learned a lot about codes and ciphers and how they work, and that was the best part of it all. I liked the writing, so I think I might pick up another Simon Singh book in the future.

In the appendix, he discusses other famous attempts at breaking codes, including the recent book, The Bible Code, by Michael Drosnin.

I have a romantic view of old-fashioned, analog cryptography (and stenography). Every time I read about it, I feel like a kid again, sitting in a treehouse with the neighboring kids who make up our small detective/spy club, encrypting messages we hoped someone would care to attempt to read. If I were born a decade or two earlier, I surely would have become a ham radio operator. Recommendations for spy novels that capture this childish feeling are appreciated.

Cryptography 101: Basic Solving Techniques for Substitution Ciphers

It doesn’t matter whether a cryptogram presents you with letters, numbers, arcane symbols, lines and dots, or weird alien squiggles — if you’re asked to replace each letter in the alphabet with another symbol, you’re dealing with a simple substitution cipher.

All substitution ciphers can be cracked by using the following tips:

Cracking The Dream Code Book Free Download

  • Scan through the cipher, looking for single-letter words. They’re almost definitely A or I.

  • Count how many times each symbol appears in the puzzle. The most frequent symbol is probably E. It could also be T, A, or O, especially if the cryptogram is fairly short.

  • Pencil in your guesses over the ciphertext. Do typical word fragments start to reveal themselves? Be prepared to erase and change your guesses!

  • Look for apostrophes. They’re generally followed by S, T, D, M, LL, or RE.

  • Look for repeating letter patterns. They may be common letter groups, such as TH, SH, RE, CH, TR, ING, ION, and ENT.

  • Try to decipher two-, three-, and four-letter words.

    • Two-letter words almost always have one vowel and one consonant. The five most common two-letter words, in order of frequency, are OF, TO, IN, IS, and IT.

    • The most common three-letter words, in order of frequency, are THE, AND, FOR, WAS, and HIS.

    • The most common four-letter word is THAT. An encrypted word with the pattern 1 – – 1 is likely to be THAT. However, the pattern 1 – – 1 also represents 30 other words, so keep this in mind!

  • Scan for double letters. They’re most likely to be LL, followed in frequency by EE, SS, OO, and TT (and on to less commonly seen doubles).

Understanding the Freemason’s Cipher

Freemasons have used ciphers since at least the 18th century. The Freemason’s Cipher is sometimes called the Pigpen Cipher, because the alphabet is written into a grid of lines, which may look like pigpens, and a cross shape from two diagonal lines. A letter is enciphered by drawing the shape of the cell that encompasses it. Freemasons learned one of the many versions of this cipher as part of the Royal Arch initiation.

Here are the main reasons Freemasons use ciphers:

Cracking The Code Pete Hendrickson

  • To keep their ritual ceremonies secure so they aren’t easily discovered by the unitiated

  • To keep messages about Masonic business (like “lodge officers meet one half-hour before the meeting of the full lodge”) just among Masons

  • To have fun, plain and simple

The Grand Lodge style of Freemasonry began in 1717 in London, England, and spread to France in fewer than ten years. In France, Freemasons experimented with the development of so-called high degrees, ritual initiation ceremonies that somehow went beyond the first three degrees of Freemasonry.

These high degree ceremonies were plays that enhanced a Mason’s experience and interaction with the legends, for example, of the Temple built by King Solomon. Some believe that the French invented a degree called the Royal Arch, as a kind of completion (keystone) of the third or Master Mason degree.

However the Royal Arch was developed — and early Masonic records are notoriously incomplete — history suggests that the Royal Arch degree was being conferred in London in the 1740s. When it comes down to it, the Freemason’s Cipher (in any version) is a straight substitution cipher, so you can solve it by substituting a letter for each symbol.

Crack the Code and Find the Secret Word

Cracking Codes & Cryptograms For Dummies has something extra — a secret word within the book for you to discover! This secret word isn’t listed in the Hints or Answers, and it isn’t mentioned anywhere within the book. The only way you can discover it is by solving the puzzles.

Here are a few pointers to get you started on the trail:

  • The secret word occurs as a keyword within one of the substitution cryptograms.

  • The cryptogram in question doesn’t have any introductory text saying that the puzzle has a keyword.

  • Decrypt the cryptograms in the usual way. To reveal any possible keywords, write out the plaintext and cipher alphabet in two rows (a toz on the top line, and the encrypted cipher letters on the second line, beneath the alphabet). If the puzzle has a keyword, you’ll see a sequence of letters that spells out a word within the cipher alphabet.

  • The secret word has more than three letters.

  • Not all keywords are placed at the start of the alphabet.
