# Simple captcha module

## Description

This module provides a simple captcha ("Completely Automated Public Turing test to tell Computers and Humans Apart")
challenge (distorted characters in an image).

It is used to ensure that only a user who can read the distorted characters and enter them in the related input field
can submit the following forms:
 - contact
 - invite
 - pricealarm (not bound in twig)

The captcha module then validates the submitted value against the expected one and then decides whether to process the
request (e.g. send contact mail to shop administrator) or refuse and show an error message instead.
