Book Description
Explore the fascinating and rich world of Secret Key cryptography! This book provides practical methods for encrypting messages, an interesting and entertaining historical perspective, and an incredible collection of ciphers and codes—including 30 unbreakable methods. In Secret Key Cryptography: Ciphers, from simple to unbreakable you will: Measure the strength of your ciphers and learn how to guarantee their security Construct and incorporate data-compression codes Generate true random numbers in bulk Construct huge primes and safe primes Add an undetectable backdoor to a cipher Defeat hypothetical ultracomputers that could be developed decades from now Construct 30 unbreakable ciphers Secret Key Cryptography gives you a toolbox of cryptographic techniques and Secret Key methods. The book’s simple, non-technical language is easy to understand and accessible for any reader, even without the advanced mathematics normally required for cryptography. You’ll learn how to create and solve ciphers, as well as how to measure their strength. As you go, you’ll explore both historic ciphers and groundbreaking new approaches—including a never-before-seen way to implement the uncrackable One-Time Pad algorithm. Whoever you are, this book is for you! History buffs will love seeing the evolution of sophisticated cryptographic methods, hobbyists will get a gentle introduction to cryptography, and engineers and computer scientists will learn the principles of constructing secure ciphers. Even professional cryptographers will find a range of new methods and concepts never published before. About the technology From the Roman empire’s Caesar cipher to the WWII Enigma machine, secret messages have influenced the course of history. Today, Secret Key cryptography is the backbone of all modern computing infrastructure. Properly designed, these algorithms are efficient and practical. Some are actually unbreakable, even using supercomputers or quantum technology! About the book Secret Key Cryptography teaches you how to create Secret Key ciphers, ranging from simple pen-and-paper methods to advanced techniques used in modern computer-based cryptography. It reveals both historic examples and current innovations. You’ll learn how to efficiently encrypt large files with fast stream ciphers, discover alternatives to AES encryption, and avoid strong-looking but weak ciphers. Simple language and fun-to-solve mini-ciphers make learning serious concepts easy and engaging. What's inside Construct 30 unbreakable ciphers Measure the strength of your ciphers and guarantee their security Add an undetectable backdoor to a cipher Defeat hypothetical ultracomputers of the future About the reader For professional engineers, computer scientists, and cryptography hobbyists. No advanced math knowledge is required. About the author Frank Rubin has been doing cryptography for over 50 years. He holds an MS in Mathematics, and a PhD in Computer Science.

Book Description
It was 1798 when the Morningstarr twins arrived in New York with a vision for a magnificent city: towering skyscrapers, dazzling machines, and winding train lines, all running on technology no one had ever seen before. Fifty-seven years later, the enigmatic architects disappeared, leaving behind for the people of New York the Old York Cipher--a puzzle laid into the shining city they constructed, at the end of which was promised a treasure beyond all imagining. By the present day, however, the puzzle has never been solved, and the greatest mystery of the modern world is little more than a tourist attraction. Tess and Theo Biedermann and their friend Jaime Cruz live in a Morningstarr apartment--until a real estate developer announces that the city has agreed to sell him the five remaining Morningstarr buildings. Their likely destruction means the end of a dream long held by the people of New York. And if Tess, Theo, and Jaime want to save their home, they have to prove that the Old York Cipher is real. Which means they have to solve it.

Book Description
“Jam packed with insights from women in the field,” this is an invaluable career guide for the aspiring or experienced female tech professional (Forbes). As the CEO of a startup, Tarah Wheeler is all too familiar with the challenges female tech professionals face on a daily basis. That’s why she’s teamed up with other high-achieving women within the field—from entrepreneurs and analysts to elite hackers and gamers—to provide a roadmap for women looking to jump-start, or further develop, their tech career. In an effort to dismantle the unconscious social bias against women in the industry, Wheeler interviews professionals like Brianna Wu (founder, Giant Spacekat), Angie Chang (founder, Women 2.0), Keren Elazari (TED speaker and cybersecurity expert), Katie Cunningham (Python educator and developer), and Miah Johnson (senior systems administrator) about the obstacles they have overcome to do what they love. Their inspiring personal stories are interspersed with tech-focused career advice. Readers will learn: • the secrets of salary negotiation • the best format for tech resumes • how to ace a tech interview • the perks of both contracting (W-9) and salaried full-time work • the secrets of mentorship • how to start your own company • and much more! BONUS CONTENT: Perfect for its audience of hackers and coders, Women in Tech also contains puzzles and codes throughout—created by Mike Selinker (Lone Shark Games), Gabby Weidling (Lone Shark Games), and cryptographer Ryan “LostboY” Clarke—that are love letters to women in the industry. A distinguished anonymous contributor created the Python code for the cover of the book, which references the mother of computer science, Ada Lovelace. Run the code to see what it does!
