Is Rust's MD5 Slow? Heck no!

Today I came across this post on the Rust subreddit. Basically it is comparing two MD5 Miners written in Python and Rust. The miner is written for a code challenge called Advent of Code.

To be honest, speed is one of the things I love about Rust, so seeing Rust being blown away by Python (which I also like and use a lot) made me sad. I decided to make this a bit more fair for Rust so I made a very short piece of Rust code to complete this challenge FAST.

The challenge

The challenge, as written on the Advent of Code page is as follows:

• You are given a key, for example abcdef.
• You are looking for a string that is made by taking the MD5 of this key plus a number. This hash has to start with 5 leading zeros. (Like abcdef609043)

Auto-enable Local HTTP Caching in Test Kitchen

Note: total experiment and hack, looks nasty, could be awesome:

Setup

• Drop the kitchen.local.yml into $HOME/.kitchen/config.yml
• Install polipo (with Mac: brew install polipo, with Ubuntu: apt-get install polipo)
• Drop polipo-start and polipo-console somewhere useful (perhaps $HOME/bin?)
