MDN Reference: AuthenticatorResponse on MDN

The AuthenticatorResponse interface of the Web Authentication API is the base interface for interfaces that provide a cryptographic root of trust for a key pair. The child interfaces include information from the browser such as the challenge origin and either may be returned from PublicKeyCredential.response. https://developer.mozilla.org/en-US/docs/Web/API/AuthenticatorResponse

Examples

SpawnDev.SpawnJS Mapping Note: The JavaScript examples below show the standard Web API usage. In SpawnDev.SpawnJS, the same API is available with C# conventions:

• Properties and methods use PascalCase (e.g., readyState becomes ReadyState)
• Events use ActionEvent with +=/-= (e.g., addEventListener("click", fn) becomes OnClick += handler)
• Async methods return Task<T> instead of Promise<T>
• Objects should be disposed with using statements
• Access via JS.Get<AuthenticatorResponse>(...) or constructor new AuthenticatorResponse(...)

Getting an AuthenticatorAssertionResponse

const options = {
  challenge: new Uint8Array([
    /* bytes sent from the server */
  ]),
};

navigator.credentials
  .get({ publicKey: options })
  .then((credentialInfoAssertion) => {
    const assertionResponse = credentialInfoAssertion.response;
    // send assertion response back to the server
    // to proceed with the control of the credential
  })
  .catch((err) => console.error(err));

Getting an AuthenticatorAttestationResponse

const publicKey = {
  challenge: new Uint8Array([
    21, 31, 105 /* 29 more random bytes generated by the server */,
  ]),
  rp: {
    name: "Example CORP",
    id: "login.example.com",
  },
  user: {
    id: new Uint8Array(16),
    name: "msanchez@example.com",
    displayName: "Maria Sanchez",
  },
  pubKeyCredParams: [
    {
      type: "public-key",
      alg: -7,
    },
  ],
};

navigator.credentials
  .create({ publicKey })
  .then((newCredentialInfo) => {
    const attestationResponse = newCredentialInfo.response;
  })
  .catch((err) => console.error(err));
