Deprecation From U2F API to WebAuthn

• python-u2flib-server

  2 286 0.7 Python

  Discontinued Python based U2F server library

  

We’ll be using Python for the backend APIs. The U2F API sequence (left) is very similar to the WebAuthn sequence (on the right). We simply have to replace three API calls: u2f.start_authentication() and u2f.finish_authentication() in the backend, and u2f.sign() in the frontend.

• python-fido2

  Provides library functionality for FIDO 2.0, including communication with a device over USB.

  

To start the migration process, let’s first replace u2f.start_authentication() with its counterpart. The data types that the WebAuthn API takes are not quite the same ones used in U2F API. In fact, one of the main pain points was converting the necessary fields into the correct data type.

Once the registration data is received by the browser, we convert the string into a buffer and decode it with this library. This gives us the data that will be used as the input parameter of navigator.credentials.create():
