Jwt
This is a PHP library for generating, parsing, and validating JSON Web Tokens and JSON Web Signatures. It serves as a cryptographic claim handler and token validation engine used to securely exchange identity information between services.
The project provides an implementation of the JSON Web Signature standard to create signed digital tokens. It allows for the encoding of identity claims and the application of cryptographic signatures to ensure data transmission remains secure.
The library covers the full lifecycle of token management, including the creation of signed tokens, decoding of token strings to retrieve payload data, and the verification of signatures to ensure authenticity and data integrity.
Features
- JSON Web Tokens - Implements the JSON Web Token standard for creating and parsing signed tokens to exchange identity claims.
- Cryptographic Token Generators - Implements tools for creating and signing digital tokens to prove identity and secure data transmission.
- JSON Web Signatures - Implements the JSON Web Signature standard to create and verify cryptographically signed payloads.
- Claim Handling - Provides utilities for encoding and decoding secure identity claims within a standardized token format.
- Token Signature Verification - Validates the cryptographic signatures of tokens to ensure authenticity and data integrity.
- Token Validation Services - Provides utilities for verifying the integrity and authenticity of security tokens through signature checks.
- Payload Decoding - Allows decoding of encoded token strings to retrieve payload data and claims for application use.
- API Access Control - Enables secure API access control by issuing and validating cryptographically signed tokens.
- Identity-Based Authentication - Verifies token authenticity to confirm user identities without requiring a database lookup on every request.
- Authentication and Authorization - Generates and validates JSON Web Tokens.
