Auth

Initialize/Constructor

var criiptoAuth = new CriiptoAuth({
  domain: '{YOUR_CRIIPTO_DOMAIN}',
  clientID: '{YOUR_CRIIPTO_APPLICATION_ID}',
  store: sessionStorage
});

var criiptoAuth = new CriiptoAuth({
  domain: '{YOUR_CRIIPTO_DOMAIN}',
  clientID: '{YOUR_CRIIPTO_APPLICATION_ID}',
  store: sessionStorage,
  redirectUri: 'http://localhost:8000/example/index.html',
  acrValues: 'urn:grn:authn:dk:nemid:poces'
});

Parameters:

  • domain (required, string): The domain which your Criipto Application belongs to, such as example.criipto.id.
  • clientID (required, string): The Client ID/realm for your Criipto Application.
  • additional authorization parameters: See Authorization parameters

Authorization parameters

All authorization methods like criiptoAuth.popup.authorize, criiptoAuth.redirect.authorize and criiptoAuth.authorizeResponsive take a set of authorization parameters. These authorization parameters can also be provided by default via the CriiptoAuth constructor.

  • redirectUri (string): The URL where Criipto will call back to with the result of a successful or failed authentication. It must be whitelisted in the "Callback URLs" in your Criipto application settings.
  • acrValues (string): What EID to use for authentication, such as urn:grn:authn:dk:nemid:poces, a list of acceptable values can be found at https://{YOUR_CRIIPTO_DOMAIN}/.well-known/openid-configuration

authorizeResponsive

criiptoAuth.authorizeResponsive({
  '(min-width: 768px)': {
    via: 'popup',
    redirectUri: 'http://localhost:8000/example/popup-callback.html',
    acrValues: 'urn:grn:authn:dk:nemid:poces',
    width: 320,
    height: 460
  },
  '(max-width: 767px)': {
    via: 'redirect',
    redirectUri: 'http://localhost:8000/example/index.html',
    acrValues: 'urn:grn:authn:dk:nemid:poces'
  }
});

Provides a convenient way to pick authorization method (popup or redirect) based on a CSS media query (screen size).

Auth.popup

authorize

const response = await criiptoAuth.popup.authorize({
  width: 300,
  height: 400,
  redirectUri: 'http://localhost:8000/example/popup-callback.html',
  acrValues: 'urn:grn:authn:dk:nemid:poces'
});
console.log(response.id_token, response.claims);

Auth.redirect

authorize

criiptoAuth.redirect.authorize({
  redirectUri: 'http://localhost:8000/example/index.html',
  acrValues: 'urn:grn:authn:dk:nemid:poces'
});

Redirects the users browser tab to the authorization url. After authorization the user will be redirected back to the provided redirectUri.

match

const match = await criiptoAuth.redirect.match();
console.log(match.code);
console.log(match.id_token, match.claims);

Returns an object with a code or id_token key if present in the window.location search (query params) or hash.

Logout

If you have SSO enabled for your domain and you are not using prompt=login you can use logout() to clear the users SSO session.

criiptoAuth.logout({
  redirectUri: 'http://localhost:8000/example/index.html',
});

QRCode

criiptoAuth.qr.authorize(document.getElementById('qr_code_div', {
  acrValues: 'urn:grn:authn:dk:nemid:poces',
}).then(session => {
  // onAcknowledged is executed when the QR code is first scanned
  session.onAcknowledged = () => {
    console.log('Session acknowledged.');
  };

  return session.then(result => {
    console.log(result.id_token ?? result.code);
  });
}).catch(error => {
  console.error(`${error.error}: ${error.error_description}`);
});

A canvas with a QR code will be rendered inside the target element. The user can scan the QR code and then complete the Criipto login flow on their phone, however the result will end up in the initating browser (usually a desktop browser).
