# 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](https://rustup.rs): This library is a thin wrapper
|
|
over [mcaptcha-pow-ffi](./mcaptcha-pow-ffi), which has to be compiled
|
|
first before this library can be used.
|
|
2. Go
|
|
3. GNU Make
|
|
|
|
Compile Rust FFI library:
|
|
|
|
```bash
|
|
make rust.build
|
|
```
|
|
|
|
Run example:
|
|
|
|
```bash
|
|
make example
|
|
```
|
|
|
|
