FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package jwt-auth

JWT Auth

JWT Auth

A simple framework-agnostic JSON Web Token authentication solution.

Installation

Getting Started

Define the JWT Subject

Create a class (e.g., User) that implements the JWTSubject interface. This class must provide a method getJWTIdentifier to return the user’s unique identifier.

Note: This example is simplified for demonstration purposes. In a real-world application, you would typically use a proper user model, such as one provided by your framework. Ensure the getJWTIdentifier method returns a unique user identifier appropriate for your system.

Create an Authentication Provider

Create an authentication provider class that implements AuthProviderInterface. This class will handle credential validation and user retrieval by ID.

Note: This example uses hardcoded credentials for demonstration purposes. In a real-world application, you should validate credentials securely by checking against a database and using hashed passwords (e.g., via libraries like bcrypt or password_hash). Ensure you follow best practices for secure authentication.

Create a JWT Provider

Create a JWT provider class that implements JWTProviderInterface. This class should handle encoding and decoding JWT tokens.

Note: This examples used base64_encode and base64_decode for simplicity. For real-world usage, consider using a proper JWT library such as firebase/php-jwt for better security.

Generate JWT Claims

The ClaimsFactory class helps create a JWT claims instance. The build method accepts an array of claims and returns an instance of ClaimsInterface.

Note: This example uses hardcoded Unix timestamps for demonstration purposes. Consider using libraries like nesbot/carbon or PHP's native DateTime class to generate timestamps dynamically. This helps improve readability and ensures accurate date handling.

Initialize the JWT Authenticator

Create a new instance of the JWTAuth class. This requires an instance of AuthProviderInterface, JWTProviderInterface, and ClaimsInterface.

Usage

Attempt Authentication

Authenticate a user by providing their credentials. If successful, a JWT token will be returned. If the credentials are invalid, an InvalidCredentialsException will be thrown.

Authenticate a Token

Validate a JWT token and retrieve the associated user (subject).
