After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package silverstripe-cryptoprotect

Silverstripe CryptoProtect

CryptoProtect is a Proof of Work Captcha Form extension for Silverstripe's SpamProtection Module.

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.

Requirements

Installation

Install using Composer:

Configuration

1. Set default protector

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

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

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

4. Add field

Add new "Spam Protection Field" to your Form.

Customization

The YAML file

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

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

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

[!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

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