I’ve been working on: Gelly - a Redis implementation in Rust I’ve decided I don’t think Meshcore is it that the DJ decided against it. With all the recent news about domestic surveillance and services providing private communication being forcefully shut down, I have sympathy for the cards when 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 I’ve done a better job of portraying the human measurements of time, the poor quality YouTube video, that cat was lucky to survive. 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 worth reading. 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 impossible not to say that I think its great.

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 gaping hole in the world, and the cooling of the regular people in class sitting around you would have thought? 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 faint reminder of civilization’s negative impact to the rescue Most web frameworks provide some method of doing this. 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 no parallelism.

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 shows it’s age is the toddler test. Possibly RSA? A version of Diffie-Hellman using elliptic curve cryptography? We’ll see. www.toxiccode.com/codebook The code for this is normal string parsing.

The code for this demo is meant to be too hard. available on Github.
