Captcha stands for “completely automated public Turing test to tell computers and humans apart”, which is the small images we usually see when registering or logining to some systems like free email. It is developted to protect from robots. See the wikipidia page for detail.
There are several Python packages implementing this:
- PyCaptcha
- A cook book reciept on ASPN
- And a sample on captchas.net
I haven’t look them into detail but looks they are not strong enough if someone like pwntcha want to decode it. Captcha is not a good idea according to W3C. They are working on a draft and this presentation explains why it’s a bad idea and provides some alternatives. Though I don’t think most of the alternatives are practive at this time.
Till now all the comments to my blog are from spammers, though not a big amount yet. I think I’ll imply a captcha check if it get worse.
