PHP JWT Authorization Class

Secure | Easy to Use | Session Management | Token Validation | IP Verification

Perfect for Managing Authentication and Authorization

Introduction

The PHP JWT Authorization Class provides a straightforward way to manage user authentication and authorization using JSON Web Tokens (JWT). This class is designed to handle token generation, validation, and user session management seamlessly, ensuring secure and efficient authentication for your application.

Features

• JWT Encoding and Decoding: Securely encode and decode JWTs.
• User Authentication: Authenticate users and manage user sessions.
• Token Validation: Validate JWTs to ensure they haven't been tampered with.
• IP Verification: Ensure the IP address remains consistent during a session.
• Session Management: Manage user sessions with automatic logout and token renewal.

Installation

1. Clone the repository:

git clone https://github.com/samirkl/PHP-Authenticate-System.git

1. Install dependencies:

composer require firebase/php-jwt

Usage

Include the Authorize class in your project and use its methods to manage authentication.

Generate Token

• To generate a JWT for a user:

<?php
require 'Authorize.php';

// User information to protect
$userData = [
    'username' => 'bond',
    'password' => 'hashed_password',
    'name'     => 'James Bond',
    'phone'    => '123-456-7890',
    ...
];

// Authenticate user and set session
Authorize::auth($userData);

Verify Token

• To verify the user's identity using a token:

<?php
require 'Authorize.php';

try {
    $isApi = true; // Set to true if this is an API call
    $isAuthenticated = Authorize::verifyIdentity($isApi);

    if ($isAuthenticated) {
        // User is authenticated
        echo 'User is authenticated';
    } else {
        // Authentication failed
        echo 'Authentication failed';
    }
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}

Log Out

• To log out the user:

<?php
require 'Authorize.php';

$isLoggedOut = Authorize::logOut();

if ($isLoggedOut) {
    echo 'User logged out successfully';
} else {
    echo 'User was not logged in';
}

Methods

Authorize::hash($value)

Encodes the given value into a JWT.

• Parameters: string|array $value - The data to encode.
• Returns: string - The encoded JWT

Authorize::unHash($value)

Decodes the given JWT.

• Parameters: string $value - The encoded JWT.
• Returns: string|false - The decoded data as a JSON string or false on failure.
• Throws: JsonException

Authorize::auth(array|bool $protectedData = false)

Authenticates the user and sets the session data.

• Parameters: array|bool $protectedData - User data to protect (e.g., username, password).

Authorize::verifyIdentity(bool $isApi = false)

Verifies the user's identity using the stored token.

• Parameters: bool $isApi - If true, updates the token after authentication.
• Returns: bool - True if authentication is successful, false otherwise.
• Throws: Exception

Authorize::getIPAddress()

Gets the user's IP address.

• Returns: string - The user's IP address.

Authorize::logOut()

Logs out the user by clearing the session and cookie.

• Returns: bool - True if the user was logged out, false if the user was not logged in.

Authorize::validateToken($token)

Validates the given token.

• Parameters: string $token - The JWT to validate.
• Returns: array|null - The decoded token data as an array or null on failure.
• Throws: JsonException

Authorize::isValidToken($tokenData)

Checks if the token data is valid.

• Parameters: array $tokenData - The decoded token data.
• Returns: bool - True if the token is valid, false otherwise.
