A simple interface for verifying Google reCAPTCHA responses.

You can find the gem here: RubyGems.org

gem install recaptcha_check

RecaptchaCheck#register: sets the reCAPTCHA private key to be used during verification.

RecaptchaCheck#verify: returns true if the reCAPTCHA response passes verification.

You must call RecaptchaCheck#register once early in your application to set the reCAPTCHA private key before using RecaptchaCheck#verify in other parts of your application.

RecaptchaCheck.register ENV['var_containing_your_reCAPTCHA_PrivateKey']

post '/contact' do
    require 'recaptcha_check'

    if RecaptchaCheck.verify(params)
        # mailer.send params
        redirect '/contact/sent'
    else
        redirect back
    end
end
