This is a Laravel implementation for the server-side of [Altcha](https://altcha.org/), a proof-of-work captcha that does not require any third-party service.

Installation
------------

[](#installation)

You can install the package via composer:

```
composer require grantholle/laravel-altcha
```

Optionally, publish the config file with:

```
php artisan vendor:publish --tag="altcha-config"
```

Usage
-----

[](#usage)

In `.env` (or published config file), set the following variables:

```
# Required, sort of like a password
ALTCHA_HMAC_KEY=
# Optional, defaults to SHA-256. Can be SHA-384 or SHA-512
# ALTCHA_ALGORITHM="SHA-256"
```

Out of the box, the package registers a `/altcha-challenge` endpoint to use you on your frontend.

Frontend
--------

[](#frontend)

Following the [frontend integration](https://altcha.org/docs/website-integration), use the following snippet to get a challenge:

```

```

Implementation will be different given your frontend, but here's an example Vue component to use:

```

import 'altcha'

const emit = defineEmits(['update:modelValue'])
const stateChanged = ev => {
  if (ev.detail.state === 'verified') {
    emit('update:modelValue', ev.detail.payload)
  }
}

```

In an Inertja.js form, you could use this component like so:

```

    Email

    Password

    Submit

import { useForm } from '@inertiajs/inertia-vue3'
// This is the component we made above
import Altcha from '@/components/forms/Altcha.vue'

const form = useForm({
  email: null,
  password: null,
  token: null,
})

```

Backend validation
------------------

[](#backend-validation)

To validate the frontend-generated token/payload, there's a `ValidAltcha` rule you can use, assuming the token is passed as `token` in the request:

```
use GrantHolle\Altcha\Rules\ValidAltcha;

$request->validate([
    'email' => ['required', 'email'],
    'password' => ['required'],
    'altcha' => ['required', new ValidAltcha()],
]);
```

Testing
-------

[](#testing)

```
composer test
```
