TYPO3 Extension to add hCaptcha to EXT:form - The privacy friendly captcha alternative.

Provides hCaptcha integration for TYPO3 EXT:form.

hCaptcha is a free to use alternative to Google reCaptcha with a bigger focus on privacy. It supports initiatives like PrivacyPass.

For more information, see the hCaptcha website.

Additionally, hCaptcha provides earnings for solved captchas - that can be donated to the Wikimedia foundation automatically (which is the case for the default settings of this extension).

This extension is a fork of dreistromland/typo3-hcaptcha and previously waldhacker/hcaptcha.

Quick Setup

hCaptcha is configured with a default key to make the setup as easy as possible. It is recommended to create a custom account for your site with hCaptcha and add your own keys.

• Install the extension and activate it
• Include the static template in TypoScript
• Add a hCaptcha element to a form

TypoScript Constants

Set the following constants if you are using your own account:

plugin.tx_hcaptcha {
  settings {
    publicKey = <your-public-key>
    privateKey = <your-private-key>
  }
}

Environment variables

As an alternative to the TypoScript configuration, you can also use environment variables:

• HCAPTCHA_PUBLIC_KEY
• HCAPTCHA_PRIVATE_KEY

Content Security Policy

If you are using CSP, make sure to adjust them accordingly:

• script-src should include https://hcaptcha.com, https://*.hcaptcha.com
• frame-src should include https://hcaptcha.com, https://*.hcaptcha.com
• style-src should include https://hcaptcha.com, https://*

Privacy

Make sure to inform your users of your usage of hCaptcha and what that means - especially if you are using the invisible Enterprise version.
