This is a Fork.
Universal "JSON Web Almost Everything" - JWA, JWS, JWE, JWT, JWK with no dependencies using native crypto runtimes
Implemented specs & features
The following specifications are implemented by jose
- JSON Web Signature (JWS) - RFC7515
- JSON Web Encryption (JWE) - RFC7516

1 Due to its use of BoringSSL the following is not supported in Electron
- A128KW, A192KW, A256KW, and all composite algorithms utilizing those
- secp256k1 EC curves
- Ed448, X25519, and X448 OKP Sub Types
2 RSA1_5, OKP JWK Key Type, and secp256k1 EC curve is not supported in Web Cryptography API.
3 P-521 EC curve is not supported in Safari
4 192 bit AES keys are not supported in Chromium
FAQ
Supported Versions
| Version | Bug Fixes 🐞 | New Features ⭐ | | ------- | --------- | -------- | | 3.x.x | ✅ | ✅ | | 2.x.x | ✅ until 2022-04-30 | ❌ |
What is new in v3.x?
- Revised API
- No dependencies
- Browser support (using Web Cryptography API)
- Promise-based API
- experimental (non-blocking 🎉) Node.js libuv thread pool based runtime
v2.x docs?
Semver?
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 runtime
- 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 also 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.
- it has smaller module footprints as it does not bundle unnecessary polyfills
- it does not bundle
node-forge
fallbacks when crypto runtime is unavailable - supports secp256k1, Ed25519, Ed448, X25519, and X448
Uint8Array?!
- Whenever
Uint8Array
is a valid input, so isBuffer
since buffers are instances of Uint8Array. - Whenever
Uint8Array
is returned and you want aBuffer
instead, useBuffer.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.
Most types are "any"
Install @types/node as your project's development dependency
npm install --save-dev @types/node
"Cannot find module '...' or its corresponding type declarations."
Install @types/node as your project's development dependency
npm install --save-dev @types/node
"Module '"crypto"' has no exported member '...'"
Update @types/node as your project's development dependency
npm uninstall @types/node
npm install --save-dev @types/node
"Cannot find module 'jose'"
There's no "jose" root module. Each module is to be individually imported as explained in each individual module's documentation.
"Module not found: Error: Can't resolve '...' in '...'"
Use a supported Node.js runtime and make sure whatever tools you may use for transpiling the code also support the Subpath exports ("exports") feature.
Why? Just. Why?
I was using node-jose
for
openid-client
and
oidc-provider
and came to realize its shortcomings
in terms of performance and API (not having well defined errors).
+ this was an amazing opportunity to learn JOSE as a whole
