Module jcs 

RFC 8785 JSON Canonicalization Scheme (JCS).

Produces the deterministic byte string that all co-signatures and bundle signatures attest: same logical content, same bytes, for any conforming implementation. The rules implemented here:

• object keys sorted by UTF-16 code unit sequence;
• no insignificant whitespace;
• strings serialized with the JSON minimal-escape set (\b \t \n \f \r \" \\ and lowercase \u00xx for other control characters), all other characters emitted verbatim as UTF-8;
• numbers: integers exactly; floats in shortest round-trip form (ECMAScript number-to-string), negative zero normalized to 0, NaN and infinities rejected;
• booleans and null as true / false / null.

Functions

canonical_hash

SHA-256 over the JCS canonicalization — the SIGNATIF canonical payload hash of a JSON object.
