RFC 7520
========

RFC7520 provides a comprehensive set of **examples for JOSE
(JSON Object Signing and Encryption)**, covering JWS, JWE, and JWK.
Its purpose is to give clear, interoperable, and implementation-friendly
demonstrations of how JOSE specifications should be used in practice.

These examples include complete, real-world–style values for headers,
payloads, signatures, encrypted keys, initialization vectors, ciphertext,
and authentication tags.

The examples in this RFC are frequently used as interoperability test
vectors across JOSE implementations, including ``joserfc``.

Definition
----------

RFC 7520 defines **deterministic examples** for every major JOSE workflow:

- Creating and validating a JWS (both compact and JSON serialization)
- Encrypting and decrypting a JWE (compact and JSON serialization)
- Multiple-signature and multiple-recipient JOSE objects
- Public and private JSON Web Keys (JWK)
- Algorithms, and key wrapping
- Cross-RFC examples linking RFCs 7515–7519

These examples serve as canonical references for testing and verifying
that implementations conform to the JOSE standards.

Implementation
--------------

All examples from RFC 7520 can be validated using ``joserfc``. They are
commonly used as test vectors in the project's test suite. You can find all
the examples in ``tests/rfc7520``.
