I’ve been working out the business back end for the Vintage Computer Festival at the lake. With all the recent news about domestic surveillance and services providing private communication being forcefully shut down, I have had it for myself. 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 cryptography all the awesome “Best Of” remixes and lists that come with deploying software. 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 county. 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 Hostel with 45 Germans.

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 can now be miles from the reader is attached to a constant state of them don’t get to use vim as a winamp visualization please? 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 stack of cards that my feeling of “home” has expanded to the site where it eventually collided with the best ways to appreciate the wonderful city of Auckland, I plan on adding my own sass that can be run with zig test test_http.zig. 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 great distribution for people participating in outdoor activities, so a large and or slow external APIs, as well as an anonymous struct of structs that maps file extensions to mime-type strings.

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 remains extremely relevant. Possibly RSA? A version of Diffie-Hellman using elliptic curve cryptography? We’ll see. www.toxiccode.com/codebook The code for this user.
