Simple Captcha Mod does not work alone and is intended to work with other plugins. It is originally created for [Contact Form 7](http:\/\/contactform7.com\/), however, you can use it with your own plugin.<\/p>\n
Note: This product is "really simple" as its name suggests, i.e., it is not strongly secure. If you need perfect security, you should try other solutions.
\nalthough steps to increase security have been taken.<\/p>\n
= How does it work? =<\/p>\n
Simple Captcha Mod does not use PHP "Sessions" for storing states, unlike many other PHP CAPTCHA solutions, but stores them as temporary files. This allows you to embed it into WordPress without worrying about conflicts.<\/p>\n
When you generate a CAPTCHA, Simple Captcha Mod creates two files for it; one is an image file of CAPTCHA, and the other is a PHP file which returns the correct answer to the CAPTCHA.<\/p>\n
The two files have the same (random) prefix in their file names, for example, "a7hk3ux8p.png" and "a7hk3ux8p.php." In this case, for example, when the respondent answers "K5GF" as an answer to the "a7hk3ux8p.png" image, then Simple Captcha Mod runs "a7hk3ux8p.php" code and tests the answer against the return value it receives. If the return value is "K5GF," the two match, and the answer is confirmed as correct.<\/p>\n
