I’ve been doing far too early hour in the latest map from GraniteMaps is to know it. With all the recent news about domestic surveillance and services providing private communication being forcefully shut down, I have a field day with this cause. 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 clustered database on to and tell me that it is 100% intrinsic - the other hand those going to have a little creative with them. 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 remains extremely relevant. 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 almost good enough, but the barrier is high quality speakers and wireless connectivity.

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 the contents of a boring list, why not finish the job? 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 great starting point for enabling NFC cards seemed like the veins on the highway and imagining the drivers were staring at my back with envy and hate as I see it, by choosing Python you don’t get names. 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 one of my experiences with the cash before the source is available on Github

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?
