#### Offline RFC-7519 header and JSON claims payload formatter & expiry viewer

JWT Claims Viewer is an offline desktop RFC-7519 token header and JSON claims payload
decoder, tree formatter, timestamp inspector, and test fixture composer for Linux
developers. Parse dot-separated Base64URL segments locally on your workstation to
read structured header and payload JSON trees, convert numeric epoch claims into
UTC and local timestamps with live expiry countdowns, check RFC-7519 registered
claim fields, and generate unsigned local development fixtures.

Key Features:

* Offline Token Header & Payload Decoder: Decodes Base64URL header and payload
  segments into formatted color-coded JSON trees and computes UTC and local
  timestamps for exp, iat, and nbf with live Active, Expired, and Future badges.
* Claims Table & Structure Linter: Explains standard RFC-7519 registered claims
  (iss, sub, aud, exp, nbf, iat, jti, scope) and highlights missing expiry fields
  or malformed JSON segments.
* Sample Test Payload Composer & Report Exporter: Interactive JSON payload composer
  encoding unsigned Base64URL segments for local API development fixtures along
  with CSV and JSON inspection report export.

Disclaimer: JWT Claims Viewer is an independent open-source project by TC Studio and is not affiliated with, endorsed by, or sponsored by any third-party developer tool vendor.
