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)

Freestanding x86 itoa implementation

For use in OS development.
Designed to be assembled with NASM, porting it over to other assemblers should be easy.

License

You are free to use, modify, distribute and sell this code.
A small message referring to this gist would be nice, though not required.

Important

This implementation uses a custom calling convention.

	// Don't copy this opening PHP tag if your file already has one. That breaks things.
	<?php

	function marce_slider_before_storefront_content () {
	// If the template is not the homepage (template-homepage.php), don't display.
	if ( ! is_page_template( 'template-homepage.php' ) ) {
	return false;
	}
	// If it is the homepage, add this meta slider shortcode
	echo do_shortcode( '[metaslider id=586]');

	1) Save data when adding to cart

	When adding an item to your cart, use ld_woo_set_item_data. The best action for this to occur is
	"woocommerce_add_to_cart". The first parameter for this action contains the "cart_item_key",
	which is required for the function.
