    "JSON Web Almost Everything" - JWA, JWS, JWE, JWT, JWK, JWKS with no dependencies using runtime's native crypto in Node.js, Browser, Cloudflare Workers, Electron, and Deno.

    Implemented specs & features

    The following specifications are implemented by jose

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


    If you or your business use jose, please consider becoming a sponsor so I can continue maintaining it and adding new features carefree.


    example ESM import

    import * as jose from 'jose'

    example CJS require

    const jose = require('jose')

    example Deno import

    import * as jose from ''

    Yes. All module's public API is subject to Semantic Versioning 2.0.0.

    How is it different from jws, jwa or jsonwebtoken?

    • it supports Browser, Cloudflare Workers, and Deno runtimes
    • it supports encrypted JWTs (i.e. in JWE format)
    • supports secp256k1, Ed25519, Ed448, X25519, and X448
    • it supports JWK Key Format for all four key types (oct, RSA, EC and OKP)
    • it is exclusively using native platform Key object representations (CryptoKey and KeyObject)
    • there is JSON Web Encryption support
    • it supports the flattened JWS / JWE Serialization Syntaxes
    • it supports the "crit" member validations to make sure extensions are handled correctly

    How is it different from node-jose?

    node-jose is built to work in any javascript runtime, to be able to do that it packs a lot of polyfills and javascript implementation code in the form of node-forge, this significantly increases the footprint of the modules with dependencies that either aren't ever used or have native implementation available in the runtime already, those are often times faster and more reliable.

    • supports secp256k1, Ed25519, Ed448, X25519, and X448


    • 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.
