This Python package provides modules implementing clients for both reCAPTCHA and reCAPTCHA Mailhide.

reCAPTCHA hinders automated abuse of web sites (such as comment spam or bogus registrations) by using a CAPTCHA to try to ensure that humans are involved.

reCAPTCHA Mailhide allows web sites to obfuscate email addresses, revealing them only if a reCAPTCHA is solved.

These modules access a web service that requires sites running the reCAPCHA client to register (at no cost) for an API key. On the other hand, no imaging libraries or complex computations are needed to generate and check CAPTCHAs.
