JSON Web Token (JWT) Debugger & Verifier

Decode, inspect claims, verify HMAC signatures, and check token expiration in real time.

Strategic Context & How To Use:

Decodes, inspects, and verifies JSON Web Tokens (JWT) with client-side base64url parsing, expiration (`exp`) timestamp checks, and claim payload formatting. All decoding happens 100% locally in your browser memory, ensuring confidential authorization bearer tokens and user claims are never transmitted to any third-party server.

Sample Tokens:
Encoded Token
Unverified

Token Status: Active

Expires in 2 hours, 14 minutes
