Captcha
=======

[](#captcha)

A library trying to secure form submits without the need of separate user input (code read from distorted image).

Mode of operation
-----------------

[](#mode-of-operation)

Class "Code" generates an array with seven keys. It depends on the current server time which keys will become set with values and which not. The idea is to create seven input elements in a form, put the values from the generated array into the input elements, submit these values along with the other input data from user, restore the original code array from incoming request on server side and validate the restored array against class "Code" again.

So basically the only methods you need after instance object from class `\DMo\Captcha\Code`, are `get` to fetch the generated code and `validate` to compare restored array from request.

You can use class `\DMo\Captcha\HTMLGenerator` to generate the html-code for the input elements from instance of class `\DMo\Captcha\Code` and also to restore the code array from incoming request parameters after the form submit.

Please have a look to the examples for more clarity.
