While only a few routes implement this - such as SyncRegistration - we do not mind heavily if another client developed by a third party utilizes routes with only hashed/unhashed tokens.
Nintendo makes the unfortunate decision of sending the plaintext token to the client in a few requests.
Instead of storing a SHA-256 hash of the MD5 we expect from the Wii, we now store both the computed MD5 and plaintext generated token during registration.
The author of this commit apologizes.
Instead of individual handlers, each request deals with one Envelope. This allows fine-tuned error control, along with what's effectively middleware for authentication.
