Bug 1387820 - WebAuthn WD-05 Get Assertion Data Fix r=keeler The WebAuthn WD-05 specification's Get Assertion method defines the returned AuthenticatorAssertionResponse as providing ClientData, AuthenticatorData, and the Signature from the Authenticator. Our implementation is incorrectly setting AuthenticatorData and Signature: AuthenticatorData as a structure is intended to mirror the structure from the AuthenticatorData [1] section of the Attestation CBOR Object [2] in the MakeCredential method, which we weren't doing _at all_. This is clarified in the editor's draft of the specification, soon to be WD-06. Signature for U2F Authenticators is defined as the "attestation signature", [3] which is under-specified and we assumed would be the raw output from the U2F Authenticator [4]. This should instead be the raw ANSI X9.62 signature with no additional bytes.
