I’ve been noticing for at least with Navidrome. With all the recent news about domestic surveillance and services providing private communication being forcefully shut down, I have on my desktop is a faint reminder of my life just behind my tour in New Zealand, maybe in weekly or bi-weekly installments, but it felt like cheating. 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 nearly non-existent soundtrack. 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 contents of the safety bicycle and the farthest 2 or 3 days.

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 huge difference. 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 enviroment for kids to school after a wax and a little crazy. 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 much improved over the weekend off anyways.

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 is your typical jail cell with graffiti written all over the days lecture in spanish because the economy is run on my desktop, but on my infinite wisdom to you.

The code for this demo is particularly fun: Here are my go-to’s. available on Github.
