If you really love that library, then you can help me out for a couple of 🍻!
We highly recommend you to use the new JWT Framework project instead of this library.
- Active support of this library is provided until end of 2018.
- Security support will be provided from 2019 and up to end of 2020.
A migration guide will be/is available in the documentation of the new project.
This library provides an implementation of:
- JWS JSON Web Signature (RFC 7515),
- JWT JSON Web Token (RFC 7519),
- JWE JSON Web Encryption (RFC 7516),
- JWA JSON Web Algorithms (RFC 7518).
- JWK JSON Web Key (RFC 7517).
- JSON Web Key Thumbprint (RFC 7638).
- Unencoded Payload Option RFC7797.
JWS or JWE objects support every input that can be encoded into JSON:
-
string,array,integer,float... - Objects that implement the
\JsonSerializableinterface such asJWKInterfaceorJWKSetInterface
The detached content is also supported.
Unencoded payload is supported. This means you can sign and verify payload without base64 encoding operation.
As per the RFC7797, the b64 header MUST be protected.
When b64 header is set, the crit protected header with value b64 in its array of values is mandatory.
- Compact JSON Serialization Syntax (JWS/JWE creation and loading)
- Flattened JSON Serialization Syntax (JWS/JWE creation and loading)
- General JSON Serialization Syntax (JWS/JWE creation and loading)

The release process is described here.
This library needs at least:
,
- OpenSSL extension.
Please consider the following optional requirements:
- For AES-GCM based algorithms (
AxxxGCMandAxxxGCMKW) if not on PHP 7.1+: PHP Crypto Extension (at leastv0.2.1) is highly recommended as encryption/decryption is faster than the pure PHP implementation. - For Ed25519 algorithm: php-ed25519-ext required
- For X25519 algorithm: php-curve25519-ext required
Please read performance test results below concerning the ECC based algorithms. As the time needed to perform operation is long compared to the other algorithms, we do not recommend their use.
It has been successfully tested using PHP 7.0, PHP 7.1 and PHP7.2 with all algorithms.
If you use PHP 5.6, please install the version ^6.0 of this project.
Tests vectors from the RFC 7520 are fully implemented and all tests pass.
We also track bugs and code quality using Scrutinizer-CI and Sensio Insight.
Coding Standards are verified by StyleCI.
Code coverage is analyzed by Coveralls.io.
The preferred way to install this library is to rely on Composer:
composer require spomky-labs/joseHave a look at How to use to know how to load your JWT and discover all possibilities provided by this library.
Please read the performance page to know how fast are the algorithms supported by this library.
Requests for new features, bug fixed and all other ideas to make this library useful are welcome. If you feel comfortable writting code, you could try to fix opened issues where help is wanted or those that are easy to fix.
Do not forget to follow these best practices.
