# jose

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

## Implemented specs & features

The following specifications are implemented by `jose`

- JSON Web Signature (JWS) - [RFC7515][spec-jws]
- JSON Web Encryption (JWE) - [RFC7516][spec-jwe]
- JSON Web Key (JWK) - [RFC7517][spec-jwk]
- JSON Web Algorithms (JWA) - [RFC7518][spec-jwa]
- JSON Web Token (JWT) - [RFC7519][spec-jwt]
- JSON Web Key Thumbprint - [RFC7638][spec-thumbprint]
- JSON Web Key Thumbprint URI - [RFC9278][spec-thumbprint-uri]
- JWS Unencoded Payload Option - [RFC7797][spec-b64]
- CFRG Elliptic Curve ECDH and Signatures - [RFC8037][spec-okp]
- secp256k1 EC Key curve support - [JOSE Registrations for WebAuthn Algorithms][spec-secp256k1]

The test suite utilizes examples defined in [RFC7520][spec-cookbook] to confirm its JOSE
implementation is correct.

## FAQ

#### Supported Versions

| Version | Security Fixes 🔑 | Other Bug Fixes 🐞 | New Features ⭐ |
| ------- | --------- | -------- | -------- |
| [v4.x](https://github.com/panva/jose/tree/v4.x) | ✅ | ✅ | ✅ |
| [v3.x](https://github.com/panva/jose/tree/v3.x), [v2.x](https://github.com/panva/jose/tree/v2.x), [v1.x](https://github.com/panva/jose/tree/v1.x) | ✅ | ❌ | ❌ |

#### Uint8Array?!

- Whenever `Uint8Array` is a valid input, so is [`Buffer`](https://nodejs.org/api/buffer.html#buffer_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.
