Book Description
Learn how to program in Python while making and breaking ciphers—algorithms used to create and send secret messages! After a crash course in Python programming basics, you’ll learn to make, test, and hack programs that encrypt text with classical ciphers like the transposition cipher and Vigenère cipher. You’ll begin with simple programs for the reverse and Caesar ciphers and then work your way up to public key cryptography, the type of encryption used to secure today’s online transactions, including digital signatures, email, and Bitcoin. Each program includes the full code and a line-by-line explanation of how things work. By the end of the book, you’ll have learned how to code in Python and you’ll have the clever programs to prove it! You’ll also learn how to: - Combine loops, variables, and flow control statements into real working programs - Use dictionary files to instantly detect whether decrypted messages are valid English or gibberish - Create test programs to make sure that your code encrypts and decrypts correctly - Code (and hack!) a working example of the affine cipher, which uses modular arithmetic to encrypt a message - Break ciphers with techniques such as brute-force and frequency analysis There’s no better way to learn to code than to play with real programs. Cracking Codes with Python makes the learning fun!

Book Description
You're trying to be a savvy, educated HEALTHY consumerbut the "code" is so complex! First, you have the FOOD industry .... Do you feel like you're reading a secret code when you read a food label or ingredient list? Terms such as "organic" "lite" "kosher" "vegan" "lactose free" "pareve" (or parve). Labels also contain symbols and letters! And while ingredients such as corn starch may be familiar to most, ingredients such as butylated hydroxytolunene are not. To confuse you even more (and get your money) manufacturers use different names for the same ingredient! To complicate the "code" furtherthe DIET industry! Wouldn't it make sense to find out what makes you want to eat more, depletes your energy, and makes you sick? Every day there is an abundance of diet information (and diet foods) available, but Americans are more confused (and less healthy) than ever. Learn how you can STOP becoming a "slave to the cycle" of dieting, depression, energy depletion and sicknessand start living a life filled with energy overload and healthful abundance. Potions, pills, diet food, and drinksOh my! Don't be a statistic any longer. Get ready to crack the code.

Book Description
The truth about ¿hidden symbolism¿ provides an intriguing insight into an alternative historical narrative. The proponents of a different story found a way to write their own version of historical events: they encoded it in symbolism secretly hidden in the very works of art that were commissioned by their enemies, the established Church. This book will inspire you to search out artifacts, paintings and architecture, decipher the hidden codes, and experience the almost mystical sensation of discovering the secret messages meant for us and our descendants as much as for the artists¿ contemporaries. The author was the co-author of ¿Rosslyn -- Guardian of the Secrets of the Holy Grail,¿ which Dan Brown drew upon as source material for his, `The Da Vinci Code.¿

Book Description
Expanding on issues touched on in The Da Vinci Code, this thought-provoking study explores the real story of Christianity—a story told by men and women condemned by the traditional, orthodox church, and one long hidden in mysterious codes and symbols. In medieval times, dissenters believed the established church ruthlessly suppressed the truth about Jesus and his ministry. Branded as heretics and subject to torture and execution for their beliefs, the dissenters—including the Knights Templar, Freemasons, Cathars, and groups of scientists—devised an ingenious code to communicate with fellow sympathizers and preserve the truth. They concealed these complex symbols in art, artifacts, and architecture of the medieval world. Finally, this fascinating underground language is deciphered…revealing powerful messages meant as much for today’s truth seekers as for medieval minds.
