SAMPLE JWS — Flattened JSON Serialization

The single-signature flattened JSON form of the exact same RS256 token shipped in compact serialization. Both encodings must verify to the identical payload, which is the round-trip this pair is for.

What is a .json file?

JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format representing objects, arrays, strings, numbers, booleans, and null. It is language-independent, human-readable, and the dominant format for web APIs and configuration. It requires a single well-formed root value.

How to use this file

Use an example JSON file to test parsers and serializers, schema validation, Unicode and number-precision handling, and API request or response processing.

How to use this file for testing

“SAMPLE JWS — Flattened JSON Serialization” is a deterministic Novus Examples fixture for JWT / JWKS testing, API testing. Unsigned and SAMPLE-signed JWT variants plus JWKS documents — published sample material only, for auth parser tests.

Documented properties for this file: seed 70117. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

This is published, SAMPLE-only security material — never a real secret. Point certificate, key, or token parsers at it, test PEM/DER decoding and PKCS handling, and confirm your tooling reads the documented fields; any sample password is printed on this page.

These JSON fixtures are synthetic SAMPLE auth or tool-call shapes for harnesses — never production secrets or live tokens. Validate schema fields and alg variants against the documented role.

Code examples

import json

with open("jws-flattened-json.json") as f:
    data = json.load(f)
print(type(data), len(data))
