As the General JWS JSON Serialization Syntax, the JWS JSON Serialization represents digitally signed or MACed content as a JSON object. This representation is neither optimized for compactness nor URL-safe.
The flattened syntax is optimized for the single digital signature or MAC case.
Line breaks added for readability
