Setting Up ReCaptcha

reCaptcha is a free service provided by Google that can be used for protection against spam or other forms of internet abuse by verifying whether a user is a human or a robot. It comes in the form of a widget. The following section guides you through setting up reCaptcha with the MWARE IAM and how to use it in different scenarios.

How it works

First, you will need to register and create an API key pair for the required domain. The key pair consists of a site key and secret. The site key is what is used when a reCaptcha widget is displayed on a page. After verification, a new parameter called g-recaptcha-response appears on the form that the user submits. From the server side, you can verify the submitted captcha response by calling the Google API with the secret key.

Follow the steps provided below to configure this.

Configuring reCaptcha API keys

  1. Go to https://www.google.com/recaptcha/admin.

  2. You will see the window shown below. Fill in the fields to register your ESB domain and click Register. The following are sample values:

    • Label: MWARE ESB
    • Select the reCAPTCHA V2 or Invisible reCAPTCHA option.
    • Domains: is.apim.com

  3. Take note of the site key and secret that you receive. note-site-key-secret

  4. Open the deployment.toml file located in the <API-M_HOME>/repository/conf/ directory and add the following configurations.

    # Google reCAPTCHA settings

# Enable Google reCAPTCHA
[recaptcha] 
enabled= true

# reCaptcha API URL
api_url="https://www.google.com/recaptcha/api.js"

# reCaptcha verification URL
verify_url="https://www.google.com/recaptcha/api/siteverify"

# reCaptcha site key
site_key="6Lc8THgUAAAAAPekxT991FGFXRrsiPCMNv5PwZHB"

# reCaptcha secret key
secret_key="6Lc8THgUAAAAAEu83iOwSin_CSt6gqe97aa7EGFd"

parameters_in_url_enabled = true

    Note

    If you have additional authorization endpoints, you need to include the login.do URL paths of these endpoints. Here, url_path is the URL without the host parameters.

    redirect_urls="url1_path,url2_path"

    An example of how to include the URL paths of additional authorization endpoints is given below.

    redirect_urls="/authenticationendpointone/login.do,/authenticationendpointtwo/login.do"

  5. Enable reCAPTCHA from the Carbon console. (Identity Providers -> Resident -> Login Attempts Security -> reCaptcha for SSO Login -> Always prompt reCaptcha) configuring-recaptcha-from-carbon-console

  6. Restart the MWARE ESB Publisher portal.

You have successfully set up reCaptcha for your site. You can now configure reCaptcha with any of the following:
