gomcaptcha: Go library that implements mCaptcha PoW

Overview

Normal usage within mCaptcha ecosystem will look like this:

1. mCaptcha server presents challenge parameters (difficulty_factor, salt, and challenge phrase)
2. Visitor computes Proof-of-Work using parameters received
3. Visitor submits Proof-of-Work to mCaptcha server and receives authorization token if Proof-of-Work is valid.
4. Visitor submits Proof-of-Work to protected resource/server

This library implements step #2 from this process.

Dependencies

1. Rust compiler: This library is a thin wrapper over mcaptcha-pow-ffi, which has to be compiled first before this library can be used.
2. Go
3. GNU Make

Compile Rust FFI library:

make rust.build
