JWT Decoder details

Decode and inspect JSON Web Tokens locally without verifying or sending secrets. JWT Decoder is now a native Toolars workspace for local decode-only token inspection.

Overview

JWT Decoder splits JSON Web Tokens into header, payload, and signature sections, decodes JSON fields, and surfaces token metadata without sending secrets to a server. The workspace migrates the Aixtral source behavior into Toolars-native token input, decoded payload review, algorithm metadata, and explicit decode-only warnings so users do not confuse inspection with signature verification.

How it works

1Paste tokenAccept a JWT string for local parsing while warning users not to paste production secrets casually.Input

2Decode token partsReturn decoded header, payload, signature presence, algorithm, expiry hints, and structured JSON.Output

3Separate decode from verifyMake unsupported tokens, invalid segments, missing signatures, and unverifiable status clear before use.Review

4Copy local outputAdds a native decode-only workbench, token warnings, decoded JSON panels, metadata badges, and public catalog readiness.Handoff

Decode-only JWT inspection model

LocalInputs are processed in the browser by the native Toolars workspace and are not uploaded for conversion.

ReviewThe workspace decodes token contents locally and never claims signature verification or trust decisions.

PublicThis tool has a dedicated Toolars workspace, source-backed library implementation, and focused tests.
