Open-source alternatives to Php Encryption

This is a PHP library for implementing JSON Web Tokens to securely encode, decode, and verify identity claims between parties. It provides the core utilities necessary to create signed tokens and validate their authenticity to ensure data integrity. The library includes a mechanism for caching remote JSON Web Key sets locally. This reduces network requests and optimizes the process of signature verification and key rotation. Capabilities cover a range of cryptographic operations, including HMAC-based signature verification and RSA-based asymmetric signing. It handles Base64Url encoding for t

CodeIgniter is a PHP web framework built on the Model-View-Controller pattern, designed for building full-stack web applications. It provides a lightweight toolkit with minimal configuration, organizing application logic into controllers, models, and views for clean separation of concerns. The framework includes a fluent query builder for constructing SQL statements programmatically, PSR-4 autoloading with namespace mapping, and a service-based dependency injection container for managing shared class instances. The framework distinguishes itself through its comprehensive set of built-in tools
