ReCAPTCHA library - ignited

[quote author="zauber" date="1197954053"]Sorry - I really don't mean to put down your hard work - this is not a reflection on your code, just on the use of captchas in general. It should be noted that they've recently been broken. Spammers are relaying captchas to pornsites where visitors are tricked into solving them with the promise of free porn if they do. The solution is then relayed back to the spammer. [/quote]
No offense taken. I agree that spammers are taking over and rendering a lot of captchas useless. I haven't found this to be the case for recaptcha.

So only use captchas if: 1) you are aware that its only a stumbling block, and don't care because you're monitoring your system anyway - or 2) for a time delay preventing dictionary attacks on logins, etc, PROVIDED you have a really, really good captcha generator, and enforce a strong password complexity policy.[/quote]
This is good advice from a security perspective though I can't say I agree with it 100% ("all generalizations are false", hehe).

I'd recommend taking a look at how recaptcha works - it's actually very good with regards to being more difficult to hack.

[quote author="zauber"]Besides that: good work! I'm new to the community and am happy to see that it's such a vibrant and sharing one. Hope to share some of my own someday soon.[/quote]
Yes, this is a great place for collaboration and sharing. I look forward to your contributions
