Wenn Sie jemals Stunden damit verbracht haben, Dateien umzubenennen oder Hunderte von Tabelleneinträgen zu aktualisieren, dann wissen Sie, wie stumpfsinnig manche Tätigkeiten sein können. Wie wäre es, den Computer dazu zu bringen, diese Arbeiten zu übernehmen? In diesem Buch lernen Sie, wie Sie mit Python Aufgaben in Sekundenschnelle erledigen können, die sonst viel Zeit in Anspruch nehmen würden. Programmiererfahrung brauchen Sie dazu nicht: Wenn Sie einmal die Grundlagen gemeistert haben, werden Sie Python-Programme schreiben, die automatisch alle möglichen praktischen Aufgaben für Sie abarbeiten: • eine oder eine Vielzahl von Dateien nach Texten durchsuchen • Dateien und Ordner erzeugen, aktualisieren, verschieben und umbenennen • das Web durchsuchen und Inhalte herunterladen • Excel-Dateien aktualisieren und formatieren • PDF-Dateien teilen, zusammenfügen, mit Wasserzeichen versehen und verschlüsseln • Erinnerungsmails und Textnachrichten verschicken • Online-Formulare ausfüllen Schritt-für-Schritt-Anleitungen führen Sie durch jedes Programm und Übungsaufgaben am Ende jedes Kapitels fordern Sie dazu auf, die Programme zu verbessern und Ihre Fähigkeiten auf ähnliche Problemstellungen zu richten. Verschwenden Sie nicht Ihre Zeit mit Aufgaben, die auch ein gut dressierter Affe erledigen könnte. Bringen Sie Ihren Computer dazu, die langweilige Arbeit zu machen!

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!

While cracking a code might seem like something few of us would encounter in our daily lives, it is actually far more prevalent than we may realize. Anyone who has had personal information taken because of a hacked email account can understand the need for cryptography and the importance of encryption—essentially the need to code information to keep it safe. This detailed volume examines the logic and science behind various ciphers, their real world uses, how codes can be broken, and the use of technology in this oft-overlooked field.

It's known as the science of secrecy. Cryptography: the encoding and decoding of private information. And it is history's most fascinating story of intrigue and cunning. The battle between codemakers and codebreakers has been going on for centuries: from Julius Caesar and his Caesar cipher to the codebreaking achievements of the 10th-century Arabs; from the code used by Mary Queen of Scots in an attempt to dethrone Elizabeth I to Sir Francis Walsingham's decipherment of that code, which led to Mary's execution for treason; from the Germans' use of the Enigma machine for automatic encryption in the Second World War to Alan Turing's efforts to infiltrate Enigma, which contributed to the Allied victory. And the battle rages on. How private are your e-mail communications? How secure is sending your credit card information over the internet? And how much secrecy will the government tolerate? Simon Singh follows the evolution of secret writing with a clarity that lets the reader enjoy the captivating story w.
