"JSON Web Almost Everything" - JWA, JWS, JWE, JWT, JWK, JWKS for Node.js, Browser, Cloudflare Workers, Deno, and other Web-interoperable runtimes.

Implemented specs & features

The following specifications are implemented by jose

• JSON Web Signature (JWS) - RFC7515
• JSON Web Encryption (JWE) - RFC7516
• JSON Web Key (JWK) - RFC7517
• JSON Web Algorithms (JWA) - RFC7518
• JSON Web Token (JWT) - RFC7519
• JSON Web Key Thumbprint - RFC7638
• JSON Web Key Thumbprint URI - RFC9278
• JWS Unencoded Payload Option - RFC7797
• CFRG Elliptic Curve ECDH and Signatures - RFC8037
• secp256k1 EC Key curve support - JOSE Registrations for WebAuthn Algorithms

The test suite utilizes examples defined in RFC7520 to confirm its JOSE implementation is correct.

Uint8Array?!

• Whenever Uint8Array is a valid input, so is Buffer since buffers are instances of Uint8Array.
• Whenever Uint8Array is returned and you want a Buffer instead, use Buffer.from(uint8array).

Bundle Size, Package Size, Tree Shaking

Yes the bundle size is on the larger side, that is because each module is actually published multiple times so that it can remain truly without dependencies and be universal / isomorphic.

Nevertheless, since each module can be required independently and is fully tree-shakeable, the install size should not be a cause for concern.
