Document Hash Function

[maltfield]

Uhh, what hash function does mCaptcha use?

Problem

I searched the issues and I searched the README, and there's no mention of which hash function mCaptcha uses by default, and which others it supports.

This seems like critical information when deciding which type of hashcash captcha solution to use!

Solution

The solution to this problem is not to just answer me here on this GitHub issue.

The solution to this problem is to document the list of all supported cryptographic hash functions somewhere in the documentation of mCaptcha, such as the README.md file

Hi! 👋

mCaptcha is seriously lacking in documentation. I'm swamped by school at the moment, so I won't be able to get to this for another one month or so. However, mCaptcha uses SHA256 and the Rust implementation of the PoW library (which encapsulates all hashing business) is available here. It's README contains some info to get you started.

There's also a TypeScript implementation of the same with little to no docs here.
