This repository is a PHP library for creating Apple Wallet passes (.pkpass files) and related functionality. It provides classes to generate, sign, and package passes according to Apple's Wallet specifications, including support for boarding passes, store cards, event tickets, and financial orders. The library handles certificate-based signing, file inclusion, localization, and pass creation through a clean object-oriented interface. The architecture centers around the PKPass class which implements the core pass creation logic, including manifest generation, signature creation using OpenSSL, and ZIP packaging. FinanceOrder extends PKPass for financial transaction orders with order-specific constants and SHA-256 hashing. PKPassBundle enables combining multiple passes into a single .pkpasses file for bulk distribution. The Push class handles Apple Push Notification Service (APNS) integration for sending pass updates to devices. Key features include flexible data input (arrays or JSON strings), file management (local, remote, and string content), localization support, and proper error handling through custom exceptions. The library requires PHP 7.0+ with ZIP, JSON, and OpenSSL extensions, and includes comprehensive testing via PHPUnit.
