Introduction

Webauthn defines an API enabling the creation and use of strong, attested, scoped, public key-based credentials by web applications, for the purpose of strongly authenticating users.

The complete specification can be found on the W3C dedicated page.

This framework contains PHP libraries and Symfony bundle to allow developers to integrate that authentication mechanism into their web applications.

Class, Constant and Property Names

Naming things may be complicated. That’s why the following rule applies on the whole framework: the name of classes, constants and properties are identical to the ones you will find in the specification.

As an example, the shows an object named AuthenticatorAssertionResponse that extends AuthenticatorResponse with the following properties:

• authenticatorData

• signature

• userHandle

  You will find in the PHP class provided by the library.

Supported features

• Attestation Types

  • Empty

  • Basic

  • Self

Compatible Authenticators

The framework is already compatible with all authenticators except the one that use ECDAA Attestation format.

The compliance of the framework is ensured by running unit and functional tests during its development.

It is also tested using the official FIDO Alliance testing tools. The status of the compliance tests are . At the time of writing (end of January. 2020), the main features and algorithms are supported and 99% of the tests pass. Full compliance with the Webauthn specification is expected in early 2020.
