KeyCAPTCHA Unique Technologies

• Instead of guessing symbols, our CAPTCHA offers visitors to complete an easy interactive task.
• If KeyCAPTCHA hasn't been solved correctly, page refreshing doesn't take place that allows the user not to fill in the form repeatedly. It occurs since there is an initial checkup of CAPTCHAs in the KeyCAPTCHA servers before sending a filled-in form to the protected web server.
• Our CAPTCHA also can be used even if your hosting provider blocks all outgoing connections.

Effective Anti-Spam Protection

• The geo-cluster is used to operate KeyCAPTCHA service. Our geo-cluster includes the servers located in diverse European data centers. Some servers are in the special DDoS stable data centers in Switzerland to ensure trouble-free 24x7x365 mode service operation.
• KeyCAPTCHA blocks spammers using anonymizers or anonymous HTPP proxies to distribute a hand spam.
• There is no info of correct CAPTCHA solution in the visitor's browser.
• CAPTCHA verification is processed by the KeyCAPTCHA servers.
• Data transferring between your web server, the visitor's browser and the KeyCAPTCHA server is protected by a digital signature.
• 112 to 165 bit variable length password is used to generate a digital signature.
• KeyCAPTCHA is a code executable in the visitor's browser. It is not a static image as used in typical CAPTCHAs.
• Having received our CAPTCHA, it's virtually impossible to transfer it to third parties in order to run any task what spammers also do bypassing typical CAPTCHAs.
• Probability of guessing the answer by submitting a random solution is 1 to 30,000,000.
• KeyCAPTCHA-used images are transferred encryptedly.

Compatibility
KeyCAPTCHA supports two operating modes: Flash and HTML5. The KeyCAPTCHA HTML5 mode is used in most modern browsers, such as Mozilla FireFox, Google Chrome, Safari, and also used in iPhone and iPad. The Flash mode has been developed to be used in Internet Explorer and Opera. While loading, KeyCAPTCHA identifies its operating mode depending on the visitor's browser.

Can this be done for vb4 please.

Hi, lazidesis,
thank you for your interest.
We added announcement of our KeyCAPTCHA in "vBulletin 4.x Add-ons" forum.

Recently, and before this announcement, we made this compatible with any of the versions of vBulletin from 3.7 to 4.x. We thourougly tested it in all. Before, we had separate plugins for 3.7-3.8.5 and 4.x versions.

One can download and install KeyCAPTCHA plugin for VBulletin (now for versions 3.7-4x, ) directly from our site https://www.keycaptcha.com/?changelang=en . It is free but one should register there to find download and instructions specific per each of many different supported CMSs

Best,
KeyCAPTCHA Team

I've installed it in 3.7.3 and after the terms agreement page, i get a blank page. Switching back to recaptcha works just fine.
What could be the problem?

Hi, mrvanity,
thank you for your interest and time to try out our plugin!

Please open ticket on keycaptcha.com site to our support team by clicking on the "Support Team" tab
(at upper right corner of site's webpage)
then the "Add New Ticket" link.

The "Support Team" tab is visible for logged-in visitors only.
(we assume that you have already registered at our site
as you were trying to install plugin and respectively should have followed the installation instructions stipulating this).

This (opening a ticket) will permit us to communicate with you with maxima more efficiently and promptly
as we will be able to identify already entered by you related data.

Note that our team also installs our plugin free of charge if you agree to temporarily share with us your administrator access to your website (hosting share).

Waiting a ticket from you now,
KeyCAPTCHA Support Team
PS
Have you opened a ticket, we believe, your issue would have already been resolved in a very short period of time after its submission.
Anyway, sorry for this delay to answer you.

We have launched a new Email protectiion service which is not yet reflected on our website but it is fully functional and tested:

• http://hidemail.at

You may publish your Email adresses publicly (in chats, forums, twitter, facebook, etc.) as a protected from web scraper/harvesters link.
We believe that it can be also used instead of Contact US form or even by blogger that do not have access to plugin installations.

As an example, you can try out now by clicking the link:

• http://hidemail.at/6wies41pga

corresponding to

• faked@example.com

We have added server-side support (feed) in Spanish and in a dozen of other languages.

Since we have the same plug-in for all versions of vBulletin, please see a more detailed announcement in the "vBulletin 4.x Add-ons" forum

Just what i needed, Used this on a PHPBB forum :)

Hello, bailradio,
this is spectacular!

Could we ask for your time to post a couple of words (or less)
on official phpBB KeyCAPTCHA contribution
where we do not have a single positive feedback
but only posts with (transient technical support) problems?

We were kind of waiting for such feedback there for quite a time,
but it is not happening there

We would really appreciate your time and help!

very nice moD . thanks
