Module canonical 

RFC 8785 / JSON Canonicalization Scheme helpers.

These helpers canonicalize arbitrary JSON values before they are signed, verified, or hashed. The output is UTF-8 JSON with deterministic object key ordering, no insignificant whitespace, and RFC 8785-compatible number and string serialization.
