- What is f21/jwt and what does it do?
- f21/jwt is a PHP JSON Web Token library that, according to its overview, provides JWT token generation and validation plus Laravel auth integration such as a JWT guard, middleware for protected routes, and helpers for stateless API authentication. It is a low-level token library, not a complete Laravel authentication solution. Teams still need application-level user lookup, token lifecycle, revocation, and key management around it.
- Is f21/jwt maintained or archived?
- The evaluation flags f21/jwt as archived, with an unknown repository and low package score, so you should assume no upstream security patches or Laravel compatibility updates. That makes it risky for new work and security-sensitive authentication flows. If it is already in use, pin the version and plan a replacement.
- Does f21/jwt support Laravel 10 or Laravel 11?
- Compatibility cannot be confirmed from the available metadata because the repository, release history, and version constraints are not visible. The assessment says you must verify PHP version support, Laravel version constraints, PSR-4 autoloading, and Composer conflicts before assuming it works with Laravel 10 or 11. Given the archived status, expect no fixes for newer Laravel middleware or container lifecycle changes.
- How do I install f21/jwt with Composer?
- The Composer package name is f21/jwt, so installation would typically be composer require f21/jwt if it remains available. You would then follow any service provider or configuration publishing steps described by the package. However, the unknown repository and archived status mean you should not add it to a greenfield Laravel service without due diligence. Wrap it behind an application-owned token service rather than calling it directly from controllers.
- How do I generate and validate JWTs with f21/jwt?
- The overview says the library provides token generation and validation, but it does not publish enough detail here to give exact API calls safely. In practice you would issue signed tokens with required claims such as exp, iat, aud, and iss, and validate signature, algorithm, expiry, and clock skew on every request. Add tests for malformed tokens, wrong keys, and expired tokens before trusting it.
- Can f21/jwt protect Laravel API routes with middleware?
- The blurb says f21/jwt includes middleware for protecting routes and helpers for stateless API authentication, so route protection is part of its intended Laravel integration. The assessment cautions that this is below a full Laravel auth solution and should sit behind your own middleware and token service. Do not spread direct package calls across controllers and models.
- Is f21/jwt safe for production JWT authentication?
- The technical risk is high because JWT is security-critical and the package is archived with low adoption and no visible security policy. Algorithm confusion, weak key handling, missing claim validation, and token revocation gaps can cause authentication bypass or persistent unauthorized access. For production, prefer maintained primitives such as firebase/php-jwt or lcobucci/jwt, or Laravel-native Sanctum or Passport where JWT is not required.
- What are good alternatives to f21/jwt for Laravel?
- For first-party SPA, mobile, and API tokens, Laravel Sanctum is the usual choice, and Laravel Passport fits OAuth2 needs. If you specifically need JWT, use a maintained low-level library such as firebase/php-jwt or lcobucci/jwt behind a Laravel service and middleware layer. The assessment recommends these over f21/jwt for greenfield work.
- How do I migrate away from f21/jwt safely?
- Inventory every usage, pin the current version or commit, and wrap the library behind an application-owned TokenService interface with contract tests. Then run a replacement library in parallel for issuance and verification where possible, migrate consumers in stages, and decommission f21/jwt after token lifetimes expire or after a controlled revocation event. Keep the old path contained until migration is complete.
- What should I check before adopting f21/jwt for API authentication?
- Confirm the exact auth flow, required signing algorithms, key management and rotation model, token lifetime, refresh, revocation, and logout requirements. Verify PHP, Laravel, and Composer version support, OpenSSL behavior, test coverage, license, release history, and security policy. Because the repository and maintainer are not visible, due diligence cannot be completed from package metadata alone.
