Description

Discover ways to program in Python whilst making and breaking ciphers—algorithms used to create and send secret messages! 

After a crash course in Python programming basics, you’ll learn how 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 kind of encryption used to protected 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 Discover ways to:

– Combine loops, variables, and drift keep watch over statements into real working programs
– Use dictionary files to straight away detect whether decrypted messages are valid English or gibberish
– Create test programs to be sure that your code encrypts and decrypts correctly
– Code (and hack!) a case in point 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 how to code than to play with real programs. Cracking Codes with Python makes the learning fun!
