1851719 - Avoid using CryptoBuffer / fallible allocator for authenticator provided data in WebAuthn

Status: RESOLVED FIXED

(Core :: DOM: Web Authentication, enhancement, P3)

Description

[John Schanck [:jschanck]]

CryptoBuffer is a FallibleTArray<uint8_t> with some helper functions for conversions to/from other types. Using a fallible allocator adds little value when we're handling trusted outputs from the user's authenticator. We should avoid CryptoBuffer when we're handling data that is 1) known to be small and/or 2) coming from a trusted source.
