Silverstripe CryptoProtect
==========================

[](#silverstripe-cryptoprotect)

CryptoProtect is a Proof of Work Captcha Form extension for Silverstripe's [SpamProtection Module](https://github.com/silverstripe/silverstripe-spamprotection).

The Proof of Work mechanism leverages SHA256 hashing to use the computational power of the client's device, significantly deterring Spam-Bots from flooding forms.

Working demo on [iloveunix.com/contact-us](https://iloveunix.com/contact-us).

Requirements
------------

[](#requirements)

- Silverstripe CMS version 4 or 5
- Silverstripe SpamProtection Module version 3 or higher

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

[](#installation)

Install using Composer:

```
composer require minimalic/silverstripe-cryptoprotect
```

Configuration
-------------

[](#configuration)

### 1. Set default protector

[](#1-set-default-protector)

Set CryptoProtect as the default captcha in your project's config (e.g. `spamprotection.yml`):

```
SilverStripe\SpamProtection\Extension\FormSpamProtectionExtension:
  default_spam_protector: minimalic\CryptoProtect\Forms\CryptographicChallengeProtector
```

### 2. Rebuild Database

[](#2-rebuild-database)

Refresh your database by navigating to your website's root directory in the shell and running:
`vendor/bin/sake dev/build "flush=all"`

Or use your base URL with:
`/dev/build?flush=all`

### 3. Generate hashes

[](#3-generate-hashes)

In the CMS, navigate to the "admin/cryptographic-challenges" area and generate new hashes.

### 4. Add field

[](#4-add-field)

Add new "Spam Protection Field" to your Form.

Customization
-------------

[](#customization)

### The YAML file

[](#the-yaml-file)

Fine-tune the hashing mechanism in your project's config (e.g. `spamprotection.yml`). The currently available options with default values:

```
minimalic\CryptoProtect\Models\CryptographicChallenge:
  difficulty_cycles: 100000
  hashes_count: 20
  hide_input_by: 'bootstrap'
  show_calculation_status: true
  show_progress_bar: true
  hide_after_solving: true
```

Note: Increasing `difficulty_cycles` may extend calculation times on slower devices (client-side). A higher `hashes_count` requires more time for hash regeneration (server-side).

### Display options

[](#display-options)

`hide_input_by` - Hide input field by using one of available options:

- `bootstrap` default, use the "visually-hidden" class
- `style` use a "display: none" inline style
- `none` show the input field

Note

The hash input field is always shown in browsers with disabled JS as fallback to be able to resolve the challenge by hand.

`show_calculation_status` - Display a loading spinner/complete checkmark and status text

`show_progress_bar` - Display a progress bar

`hide_after_solving` - Hide the spinner/status and/or the progress bar after 4 seconds

### Finish customization

[](#finish-customization)

Remember to flush your caches (`?flush=all`) and regenerate hashes in the CMS whenever adjusting the configuration.
