Book Synopsis Cracking Codes with Python by : Al Sweigart
Download or read book Cracking Codes with Python written by Al Sweigart and published by No Starch Press. This book was released on 2018-01-23 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Mathematical Ciphers by : Anne L. Young
Download or read book Mathematical Ciphers written by Anne L. Young and published by American Mathematical Soc.. This book was released on 2006 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A cipher is a scheme for creating coded messages for the secure exchange of information. Throughout history, many different coding schemes have been devised. One of the oldest and simplest mathematical systems was used by Julius Caesar. This is where Mathematical Ciphers begins. Building on that simple system, Young moves on to more complicated schemes, ultimately ending with the RSA cipher, which is used to provide security for the Internet. This book is structured differently from most mathematics texts. It does not begin with a mathematical topic, but rather with a cipher. The mathematics is developed as it is needed; the applications motivate the mathematics. As is typical in mathematics textbooks, most chapters end with exercises. Many of these problems are similar to solved examples and are designed to assist the reader in mastering the basic material. A few of the exercises are one-of-a-kind, intended to challenge the interested reader. Implementing encryption schemes is considerably easier with the use of the computer. For all the ciphers introduced in this book, JavaScript programs are available from the Web. In addition to developing various encryption schemes, this book also introduces the reader to number theory. Here, the study of integers and their properties is placed in the exciting and modern context of cryptology. Mathematical Ciphers can be used as a textbook for an introductory course in mathematics for all majors. The only prerequisite is high school mathematics."--Jacket.

Download or read book The Mathematics of Secrets written by Joshua Holden and published by Princeton University Press. This book was released on 2018-10-02 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explaining the mathematics of cryptography The Mathematics of Secrets takes readers on a fascinating tour of the mathematics behind cryptography—the science of sending secret messages. Using a wide range of historical anecdotes and real-world examples, Joshua Holden shows how mathematical principles underpin the ways that different codes and ciphers work. He focuses on both code making and code breaking and discusses most of the ancient and modern ciphers that are currently known. He begins by looking at substitution ciphers, and then discusses how to introduce flexibility and additional notation. Holden goes on to explore polyalphabetic substitution ciphers, transposition ciphers, connections between ciphers and computer encryption, stream ciphers, public-key ciphers, and ciphers involving exponentiation. He concludes by looking at the future of ciphers and where cryptography might be headed. The Mathematics of Secrets reveals the mathematics working stealthily in the science of coded messages.

Book Synopsis Code Name Caesar by : Jerome Preisler
Download or read book Code Name Caesar written by Jerome Preisler and published by Penguin. This book was released on 2012-07-03 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the waning days of World War II, a little-known battle took place under the frozen seas off the coast of Norway . . . and changed the course of the war. In February of 1944, Germany and Japan devised a desperate plan to escape defeat. The Germans would send Japan a submarine—boat U-864—packed with their most advanced rocket and jet aircraft technology. Japan could then reestablish air superiority in the Pacific, drawing the attention of Allied forces long enough for Germany to regroup. Meanwhile, British code breakers, working with the Norwegian underground, had discovered the plan. But even though they were unable to stop the submarine from embarking, the British submarine HMS Venturer was waiting for it at sea. In a cat-and-mouse battle beneath the waves, they hunted one another, each waiting to strike. The Venturer won the game, becoming the only submarine in history to sink another sub in underwater combat. This is the dramatic, action-packed account of one of the greatest unsung victories in military history, and of a historical moment in the annals of naval warfare.
