Support prf already hashed extension (PRF#6) #38

Closed Vogeltak closed 1 month ago

Vogeltak commented 1 month ago

This PR follows on #37. It implements an unofficial variant of the PRF extension where its inputs are already hashed according to the sha256("WebAuthn PRF" || salt) format. This extension might appear on Android and must be used when mapping from Apple's authentication services.
