What is Securimage?
|
||
|
|
|
||
|
|
Securimage is a PHP class that is used to generate and validate CAPTCHA images.
|
||
|
|
The classes uses an existing PHP session or creates its own if none is found to store the
|
||
|
|
CAPTCHA code. Variables within the class are used to control the style and display of the image.
|
||
|
|
The class supports TTF fonts and effects for strengthening the security of the image.
|
||
|
|
If TTF support is not available, GD fonts can be used as well, but certain options such as
|
||
|
|
transparent text and angled letters cannot be used.
