ReCAPTCHA library - ignited

[eluser]Nick Husher[/eluser]
Unlike some previous contributors, I approve of captchas in general. There are some really bad ones, but in general they're an effective way of filtering out robots. Some people get filtered out as well, but maybe they're just robots anyway.

I'm all for moving this thread (minus the posts regarding JayTee's library) to somewhere else. I really didn't mean to start an off-topic thread, and especially not to disparage JayTee's work.

I do think it's important to have a place discuss PHP-security, especially in the context of CI, seriously. It's a far deeper and more complicated arena than I could have ever imagined before involving myself. Having looked at the security measures of CI I find they are good in many ways, but I am not really qualified to say. I have yet to see a comparative review of the security features between various frameworks from a trusted source. With more and more applications being based on frameworks, you'd think such a writeup would make an important reference and benchmark for framework developers/contributors.

Also in CI, there are several security aspects left to the discipline of the programmer/sysadmin (Access control, CSRF-protection, session-protection, password hashing, to name a few) which could possibly be implemented by various third party libraries - and in some cases attempts have probably already been made. A discussion of the various design-options for this would definitely benefit the community.

Ok... so I went off on another rant. Sorry JayTee, but since there are a few people interested in security matters on this thread already, I thought I'd try to round up some support for ... i dunno, maybe a forum-category for security discussions? Then we could move the whole captcha discussion there. I still have some thoughts and comments on captchas (and reCaptcha's implementation in particular), but I will wait for a more appropriate thread.

@zauber : create your own security topic in one of the other categories pointing to this thread as the starter for the discussion. I"m sure you will have some takers.

I'll just say, good work.

Everythings is not white or black.

Keep us posted with your more advanced implementation.

Does Recaptcha figure out a multi-language in word choice and theme ?

Thanks !

Hello JayTee,

[quote author="JayTee" date="1197951828"]Hello,
I've created a CI implementation of the reCAPTCHA service (http://www.recaptcha.net)
http://codeigniter.com/wiki/ReCAPTCHA/
[/quote]

your code didn't work for me.

On line 138 I had to change

Code:

return $this->object->load->view('recaptcha',$data,true);

into

Code:

return $this->_ci->load->view('recaptcha',$data,true);

And then the view-code is incomplete:
should probably be:

@killefiz:

Hi, I had the same problem with line 138 error and your library fix worked.

However, I think your view-code fix is missing a line or something since the javascript still doesn't call any function. what function should be called via javascript?

I'll be updating the code shortly. I've been on an extended winter vacation and am getting back to business over the next week or two.

Hi.
I get an error when I try to use it.

Code:

Fatal error: Unsupported operand types in \system\application\libraries\Recaptcha.php on line 186

I could use some help. Any ideas?

Thanks JayTee!
Your library saved my ass today.
