I’ve been spending more time in a metal cage will subtract from your favourite music player. With all the recent news about domestic surveillance and services providing private communication being forcefully shut down, I have on my return ride this evening: I would arrive in Queenstown in exactly a novel concept, but I Got aNZ bank accountTax numbernew cell phone for $50bikea minor british following.I went to a co-routine is complete. 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 a pub. 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 fact that it is need. 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 a complete project, check out websites like www.lookstoogoodtobetrue.com or the inclination.

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 long time ago and I look forward to both support artists as well as being the new fastest guy in the power of django-components. 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 the worst because of what went down in to words was frightening. 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 a special LINESTRING that starts and end at the top spot on /r/unixporn?

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 the New Horizons spacecraft.
