A PHP library for creating, parsing, and validating JSON Web Tokens (JWT) and JSON Web Signatures (JWS).
Lcobucci/JWT is a PHP library for generating, parsing, and validating JSON Web Tokens (JWT) and JSON Web Signatures (JWS). It implements the RFC 7519 standard to provide a secure and standardized way to handle token-based authentication and data transmission in web applications and APIs.
PHP developers building web applications, APIs, or microservices that require secure authentication, authorization, or stateless session management using JWTs.
Developers choose this library for its strict RFC compliance, simple API, support for multiple signing algorithms, and lightweight design that integrates easily into existing PHP projects without heavy dependencies.

Fully implements the JWT specification for interoperability with other systems, as highlighted in the key features and philosophy.
Easy to install via Composer and integrates without heavy dependencies, aligning with the library's priority on simplicity.
Supports HMAC, RSA, and ECDSA for secure token signing, providing flexibility for different security needs as per the key features.
Comprehensive documentation is hosted on Read the Docs, facilitating quick implementation and troubleshooting.
Requires manual setup for integration with popular PHP frameworks like Laravel or Symfony, unlike specialized packages that offer drop-in solutions.
Primarily handles signed tokens (JWS) and may not support JSON Web Encryption (JWE) for token encryption, which could be a gap for use cases needing confidentiality.
Setting up key management and validation rules can be verbose and error-prone, especially for developers new to JWT implementations.
