Captchas without server state

(From collective.captcha)

A view to generate a captcha image and/or wav file, and to verify user input against it.

A cookie is used to transfer state from one request to the next. The state is used, together with a server-side secret, to create a random string of characters, which in turn is displayed as a captcha image, or transformed to an audio file. Verification happens case-insensitively.

Note that the captcha 'word' is only usable for 5-10 minutes, after which the view will not accept it any more. Moreover, a different word will be generated for a given session key every 5 minutes.

This makes these captchas replayable for up to 10 minutes if a determined user keeps sending the same session id. Because of the server-secret though, captchas are not transferrable between sites.

plone.formwidget.captcha's Issues

Noise configuration

A number of bots are being able to decipher the captcha, probably using an image to text library. Is is possible to increase the noise to make them harder to the bots?

Does not work on Plone 6

WrongCaptchaCode

I'm using plone.formwidget.captcha for plone.app.discussion http://pythonhosted.org/plone.app.discussion/captcha.html
I installed the plugin by setup.py http://pastie.org/9392259
When I enabled comments by anonymous and chose Captcha (plone.formwidget.captcha) for captcha settings under Discussion settings, I'm getting this traceback when I'm posting a comment as anonymous user.
Am I missing out something?
