Online PyJWT Compiler
PyJWT is a Python implementation of RFC 7519, providing a complete JSON Web Token (JWT) library for creating, encoding, decoding, and verifying JWT tokens. As one of the most popular JWT libraries in Python, PyJWT enables secure token-based authentication and authorization in web applications, APIs, and distributed systems. JWT tokens are widely used for stateless authentication, allowing services to verify user identity and permissions without maintaining server-side sessions.
This compiler includes PyJWT with full support for JWT encoding, decoding, verification, and custom claims, all powered by Pyodide WebAssembly technology. The platform supports all core PyJWT features including encoding payloads into JWT tokens with various algorithms (HS256, RS256, etc.), decoding and verifying tokens with secret keys or public keys, handling token expiration and custom claims, working with token headers, and decoding tokens without verification for inspection. You can also upload and use files or folders directly in your code for JWT processing workflows. This compiler is online and completely free to use.
Our comprehensive example collection covers essential JWT operations including basic encoding and decoding, creating tokens with expiration times, adding custom claims to tokens, verifying tokens with secret keys, handling expired tokens, working with different algorithms, and decoding tokens without verification for inspection. You'll also learn how to implement secure authentication flows, handle token refresh scenarios, and work with JWT tokens in real-world web application and API development scenarios.
Perfect For
- Web developers implementing token-based authentication in APIs and web applications
- Backend developers building secure authentication and authorization systems
- API developers creating stateless authentication for microservices
- Security engineers working with JWT token validation and verification
