Overview of the framework
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.
This framework contains PHP libraries and Symfony bundle to allow developers to integrate that authentication mechanism into their web applications.
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.
- Attestation Types
- Private CA
- Anonymization CA
- Elliptic Curve Direct Anonymous Attestation (ECDAA)
- Attestation Formats
- FIDO U2F
- Android Key
- Android Safetynet
- Token Binding support
- Cose Algorithms
- RS1, RS256, RS384, RS512
- PS256, PS384, PS512
- ES256, ES256K, ES384, ES512
- Supported (not fully tested)
- appid extension (compatibility with FIDO U2F authenticator
The framework is already compatible with all authenticators except the ones 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 reported in this issue. At the time of writing (end of April 2021), the main features and algorithms are supported and 99% of the tests pass.
I bring solutions to your problems and answer your questions.
Requests for new features, bug fixed and all other ideas to make this framework useful are welcome.
