struct ASAuthorizationPublicKeyCredentialPRFAssertionOutput

The outputs of the WebAuthentication PRF extension, when requested during an assertion. This object represents one or two SymmetricKeys which are available anywhere the passkey can be used. These are general purpose keys which can be used for application-specific needs, such as encryption of user data. These keys should not be stored or exported. They should only ever be derived as the result of an assertion operation, and then discarded when finished.
