main interfaces...
The two main interfaces of this package are :
- Captcha : a representation of the 'are you human' test
- It is basically composed of a question, a challenge, and a validation routine.
- CaptchaFactory : the Captcha builder, that use others Core components to build captchas
...and components
This module defines also a component sub package that contains components used by factories to build captchas. Components are used by Captcha factories to build captchas.
