Ken Shirriff's blog: Mining Bitcoin with pencil and paper: 0.67 hashes per day

Sun, 28 Sep 2014 19:47:16 +0000

I decided to see how practical it would be to mine Bitcoin with pencil and paper. It turns out that the SHA-256 algorithm used for mining is pretty simple and can in fact be done by hand. Not surprisingly, the process is extremely slow compared to hardware mining and is entirely impractical. But performing the algorithm manually is a good way to understand exactly how it works.

A Few Thoughts on Cryptographic Engineering: On the NSA

Wed, 11 Sep 2013 14:28:05 +0000

All of this is a long way of saying that I was totally unprepared for today's bombshell revelations describing the NSA's efforts to defeat encryption. Not only does the worst possible hypothetical I discussed appear to be true, but it's true on a scale I couldn't even imagine. I'm no longer the crank. I wasn't even close to cranky enough.

Today, Green's academic dean contacted him to ask that "all copies" of the blog post be removed from university servers. Green said that the move was not "my Dean's fault," but he did not elaborate. Were cryptology professors at Johns Hopkins not allowed to say, as Green had, things like:

A Few Thoughts on Cryptographic Engineering: A note on the NSA, the future, and fixing mistakes

Wed, 11 Sep 2013 14:24:32 +0000

The question to me -- as an American and as someone who cares about the integrity of speech -- is how we restore faith in our technology. I don't have the answers to this question right now. Unfortunately this is a long-term problem that will consume the output of researchers and technologists much more talented than I am. I only hope to be involved in the process.

John Resig - Keeping Passwords in Source Control

Finally you’ll want to create a script (I’m using a Makefile) that the user can run to encrypt and decrypt the file. This script uses OpenSSL, and specifically CAST5, to encrypt/decrypt the file
