plone.formwidgets.hcaptcha

plone.formwidget.hcaptcha is a z3c.form widget that integrates HCaptcha into Plone websites. It provides a robust, configurable captcha solution to secure forms from automated attacks, replacing the older plone.formwidget.recaptcha package. ## Key Features - **HCaptcha Integration** — Implements the HCaptcha service for bot detection and verification. - **Configurable Control Panel** — Includes a dedicated settings panel at `@@hcaptcha-settings` for easy site key and secret key management. - **Custom Verification Endpoint** — Allows overriding the default HCaptcha API endpoint via environment variables for staging or internal testing. - **Supermodel Support** — Enables adding captcha fields directly in XML models using the `HCaptchaWidget` field type. - **Demo and Examples** — Provides a demo folder with example implementations for developers. ## Philosophy The project follows Plone's extensible architecture, offering a drop-in replacement for older captcha solutions while maintaining compatibility with Plone's form and widget ecosystems.
