Creating your own CAPTCHA provider

• Currently, you need to compile and implement the Provider within a fork of the framework itself. In the future, it will be possible to compile providers separately and install them as a plugin.

• For inspiration, see the sample providers. FilterChallenge is simple and a good starting point.

• Implement the ChallengeProvider interface, which contains these methods:

  • getId() - needs to return a string that will be used to identify the provider itself.
  • returnChallenge() - needs to return a new CAPTCHA challenge, for the configured parameters
  • checkAnswer() - check whether than answer is correct
  • configure() - (optional) use the supplied configuration
  • supportedParameters - (optional) a map of parameters and their accepted values
