## What it is
A PHP reference implementation of PASETO (Platform-Agnostic Security Tokens), a secure alternative to JWT/JWS/JWE. It supports PASETO protocol versions v3 and v4 for creating and verifying cryptographically sound tokens.

## Use cases
- issue and verify secure session tokens in PHP
- replace JWT with a safer token standard
- sign and encrypt stateless API tokens
- implement token-based authentication without JOSE pitfalls
- create platform-agnostic security tokens

## When to choose
- you need secure tokens in a PHP 8.1+ application
- you want to avoid JWT's known design flaws
- you need a well-audited reference implementation of PASETO

## When to avoid
- you must interoperate with existing JWT-based systems
- your project requires PHP older than 8.1 without upgrading
- you need PASERK key wrapping, which requires the separate paserk-php package

## Facets
- artifact type: library
- maturity: stable
- function: auth, cryptography, security, serialization
- domain: security, web-development, developer-tools
- platform: php
- tags: paseto, jwt-alternative, tokens, php-library
