Cryptographic operations like hashing and signing need the data to be
expressed in an invariant format so that the operations are reliably
repeatable. One way to address this is to create a canonical
representation of the data. Canonicalization also permits data to be
exchanged in its original form on the "wire" while cryptographic
operations performed on the canonicalized counterpart of the data in
the producer and consumer endpoints generate consistent results.
This document describes the JSON Canonicalization Scheme (JCS). This
specification defines how to create a canonical representation of
JSON data by building on the strict serialization methods for JSON
primitives defined by ECMAScript, constraining JSON data to the
Internet JSON (I-JSON) subset, and by using deterministic property
sorting.
