PHP JOSE Library

If you really love that library, then you can help me out for a couple of 🍻!

---

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.

Provided Features

Supported Input Types:

JWS or JWE objects support every input that can be encoded into JSON:

• string, array, integer, float...
• Objects that implement the \JsonSerializable interface such as JWKInterface or JWKSetInterface

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.

Supported Serialization Modes

• 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)

Supported Compression Methods

Compression Method	Supported	Comment
Deflate (DEF)	YES
GZip (GZ)	YES	This compression method is not described in the specification
ZLib (ZLIB)	YES	This compression method is not described in the specification

Supported Key Types (JWK)

Key Type	Supported	Comment
none	YES	None keys are for the none algorithm only
oct	YES	Symmetric keys
RSA	YES	RSA based asymmetric keys
EC	YES	Elliptic Curves based asymmetric keys

JWK objects support JSON Web Key Thumbprint (RFC 7638).

Key Sets (JWKSet)

JWKSet is fully supported.

The Release Process

The release process is described here.

Prerequisites

This library needs at least:

• ,
• OpenSSL extension.

Please consider the following optional requirements:

• For AES-GCM based algorithms (AxxxGCM and AxxxGCMKW) if not on PHP 7.1+: PHP Crypto Extension (at least v0.2.1) 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.

Continuous Integration

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.

Installation

The preferred way to install this library is to rely on Composer:

composer require spomky-labs/jose
