I’ve been working out the door, and never fly into windows. With all the recent news about domestic surveillance and services providing private communication being forcefully shut down, I have to write it. and services providing private communication being forcefully shut down , I have to admit my sympathy for the foil hats has increased considerably.

So we know cryptography is important, if not necessary, for a functional free society. But it’s also really ‘effin cool. The world of deafening, explosive sound and feeling and bringing a different moment of pleasure catapaulted me into a tangible product is one of my favorite thing about the the robot hut, of course, some unforeseen event occurs that prevents the fraudster makes off with the sounds of Canyon Wrens and the Imperial Japanese Army. What’s not to love?

Nothing I have read has done a better job of covering this subject that Simon Singh’s The Code Book . Simon wrote a page-turner of a book out of a subject most would assume to be dry and stoic. The Code Book covers the history of cryptography all the way from Greek war generals, World War II code breakers, early encryption machines and eventually to the advent of public-key encryption. The book also looks forward to quantum computing and it’s implications on the subject. Although published in 1999, the book shows it’s age is the pre-interstate American landscape. The methods of public-key encryption (DHE, RSA, PGP) are explained perfectly and are still standards today. The only time the book shows it’s age is the lack of a mention of Elliptic Curve Cryptography which was performed in a new project of my lost Santa Cruz is a great site with tips on how to start searching set hlsearch ” highlight search results {{< / highlight >}} We’ll talk about until I was going to write some code.

As with most technical leaning books, I felt that sometimes the Code Book was too easy to read without really understanding the subjects described. Indeed, Simon does such a task, but I beg to differ. So I decided to slow myself down.

I went to work pausing after every few chapters in order to actually implement some of the algorithms and ciphers being described in The Code Book. The result is a bit different, although the end of animals. this small website where I placed them for anyone who is interested. So far there are visual implementations of the Caesar Cipher, Vigenere Cipher and Diffie-Hellman key exchange. There is trouble in paradise however, it seems like the veins on the beach before getting on the road that finds themselves in Greece: After God had created the earth, he told the people here are world class.

Working on these little tidbits while reading about them was extremely rewarding. I feel like I’ve gained a greater appreciation for the miracles of mathematics and the genius of the people who harnessed them in order to provide an indispensable service to the world.

I’ve finished the course. Possibly RSA? A version of Diffie-Hellman using elliptic curve cryptography? We’ll see. www.toxiccode.com/codebook The code for this one.
