Description

Faris AL-Otabi

This package can verify if the user is a human with a CAPTCHA image.

It can generate an image that displays a text string generated randomly.

The generated text is stored in a session variable.

The package also verifies if the text entered by a user matches what is displayed in the image by checking the session variable.
