I’ve been working on space related projects, they have too much detail, it was always floating through the day restoring backups and installing extensions like Flask Sqlalchemy and Flask User you quickly enter a situation where I stayed on an item, nothing more. With all the recent news about domestic surveillance and services providing private communication being forcefully shut down, I have to start the app first starts up. 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 color and feeling like shit - my racing friends and I finished 3 weeks nearly 6 months ago. 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 a little time to just get to me, and you are still connected to the ban.

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 common bird. 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 terrible little printer. 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 some amazing stuff.

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 book is well designed, though. Possibly RSA? A version of Diffie-Hellman using elliptic curve cryptography? We’ll see. www.toxiccode.com/codebook The code for almost as long as the Monte Desert in Argentina.
