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!

Following the economic crisis of 2008, the website ‘bitcoin.org’ was registered by a mysterious computer programmer called Satoshi Nakamoto. A new form of money was born: electronic cash. Does Bitcoin have the potential to change how the world transacts financially? Or is it just a passing fad, even a major scam? In Bitcoin: The Future of Money?, MoneyWeek’s Dominic Frisby's explains this controversial new currency and how it came about, interviewing some of the key players in its development while casting light on its strange and murky origins, in particular the much-disputed identity of Nakamoto himself. Economic theory meets whodunnit mystery in this indispensable guide to one of the most divisive innovations of our time.

LITECOIN Grab this GREAT physical book now at a limited time discounted price! The last year saw a great surge in the popularity and public awareness of cryptocurrencies. Most of this hype was driven by the massive rocketing in the price of Bitcoin, the world's first cryptocurrency. While Bitcoin remains the most well-known cryptocurrency, there are several other popular and promising cryptocurrencies. One of this is Litecoin. Litecoin is an advanced, next-generation digital currency that allows anonymous and heavily encrypted transactions between people across a peer-to-peer (P2P) network. Like most other cryptocurrencies, Litecoin is based on blockchain technology and is not backed or controlled by any government, central bank, or central authority. Litecoin is an open source cryptocurrency, which means that anyone has the right to study its code, modify it, and distribute the software as they wish and for any purposes. Like any other currency, Litecoin can be offered in exchange for goods and services. Litecoin was released on 7 October 2011, two years after the release of Bitcoin. It was created by a former Google programmer known as Charles Lee in a bid to fix some of the shortcomings and challenges he saw in Bitcoin. Litecoin was created, or 'forked', from Bitcoin's source code, which means there are some similarities between Litecoin and Bitcoin. Since Litecoin is an offshoot of Bitcoin, it would be impossible to completely understand Litecoin without comparing the two. Therefore, there will several references to Bitcoin in this book. According to its creator, Litecoin was created to be the silver to Bitcoin's gold. Where Bitcoin is seen as the 'digital gold', as a store of value, Litecoin aims to be the 'digital silver' than can be used for daily transactions.Despite having started from very humble origins and only having a few subtle technical improvements over its big brother, Litecoin has also experienced massive growth to become the sixth largest cryptocurrency by market cap. To put the growth of Litecoin in context, I will compare it to the growth of Bitcoin. In 2017, the price of Bitcoin rose by over 1,800%, from below $1,000 in January to a few hundred dollars shy of $20,000 by the close of the year. While this might seem astronomical, it is nothing compared to the price of Litecoin, which rose by over 9,000% in the same period, starting at about $4 in January and hitting $371 by the end of the year. Litecoin currently has a market cap of about $10 billion. Here Is What You'll Learn About... Introduction To Litecoin How Litecoin Works How To Buy Litecoins Litecoin Wallets - Keeping Your Litecoins Safe Everything You Need To Know About Litecoin Mining Understanding The Impact Of SegWit And Lightning Network On Litecoin The Future Of Litecoin Should You Invest In Litecoin?
