reCAPTCHA can now be used instead of Liferay's default captcha. To configure Liferay to use reCAPTCHA, set the following in portal(-ext).properties:

captcha.engine.impl=com.liferay.portal.captcha.recaptcha.ReCaptchaImpl

You will also need to obtain a private and public key from reCAPTCHA and set the following properties:

captcha.engine.recaptcha.key.private
captcha.engine.recaptcha.key.public

UPGRADE NOTE:

As part of this improvement, captcha(-ext).properties is no longer used and the properties within this file has been moved into portal(-ext).properties.

The following is a list of the properties in captcha(-ext).properties followed by it's corresponding property in portal(-ext).properties.

cap.image.height - captcha.engine.simplecaptcha.height
cap.image.width - captcha.engine.simplecaptcha.width
cap.text.produce - captcha.engine.simplecaptcha.text.producers
