What's Recaptcha? #
Recaptcha is a Google service that generates captchas. It alternatively has sound-based captchas for the hard of sight.
Why recaptcha? #
It tends to be faster (doesn't use your servers to generate the captcha) and has the sound feature that SimpleCaptcha (the default captcha system in Liferay) doesn't have.
Enable Recaptcha in Liferay #
To enable it, add this to your portal-ext.properties (if you're in the tomcat bundle that's tomcat-{version}/webapps/ROOT/WEB-INF/classes/portal-ext.properties). If the file doesn't exist, you should create it (and read about how to configure a real database, because using HSQL for a real site is not a good idea).
Copy and paste the following, but then go to http://www.google.com/recaptcha to get your public and private keys.
## # Enable or not reCaptcha ## #recaptcha.enabled=true captcha.engine.impl=com.liferay.portal.captcha.recaptcha.ReCaptchaImpl #captcha.engine.impl=com.liferay.portal.captcha.simplecaptcha.SimpleCaptchaI captcha.check.portal.create_account=true captcha.check.portal.send_password=true captcha.check.portlet.message_boards.edit_category=false captcha.check.portlet.message_boards.edit_message=false ## # Urls to access reCaptcha services ## captcha.engine.recaptcha.url.script=http://api.recaptcha.net/challenge?k= captcha.engine.recaptcha.url.noscript=http://api.recaptcha.net/noscript?k= captcha.engine.recaptcha.url.verify=http://api-verify.recaptcha.net/verify ## #reCaptcha domain specific keys ## captcha.engine.recaptcha.key.private=YOUR KEY. FROM google.com/recaptcha. captcha.engine.recaptcha.key.public=YOUR KEY. FROM google.com/recaptcha.
NOTE: Make sure when you copy these three lines below, that you copy without the brackets:
captcha.engine.recaptcha.url.script=http://api.recaptcha.net/challenge?k=captcha.engine.recaptcha.url.noscript=http://api.recaptcha.net/noscript?k= captcha.engine.recaptcha.url.verify=http://api-verify.recaptcha.net/verify }}}
