JWT Debugger

JWT Debugger is a web-based tool designed for developers and security professionals to create, encode, decode, and debug JSON Web Tokens (JWTs). It supports various JWT algorithms, including HS256, HS384, HS512, RS256, RS384, RS512, ES256, ES384, ES512, and none.

Key features include:

• JWT Creation: Allows users to generate JWTs by providing header, payload, and signing key information.
• JWT Decoding: Decodes existing JWTs to reveal their header, payload, and signature components.
• Algorithm Support: Supports a wide range of JWT signing algorithms.
• Base64 Encoding Toggle: Offers an option to encode the header and payload using Base64.
• In-Browser Verification: Performs JWT verification directly in the browser.

Use cases:

• Debugging JWT-based authentication flows.
• Verifying the structure and content of JWTs.
• Creating test JWTs for application development.
• Analyzing JWTs for potential security vulnerabilities.
