Smart Decoder – JWT, Base64, Hash & Timestamp Toolkit

All-in-one developer toolkit to decode, encode and inspect data directly inside VS Code.

Decode JWTs beautifully, convert Base64 & Hex, transform Unix timestamps, generate MD5/SHA256 hashes, handle URL encoding — all locally, fast, without leaving your editor or using risky online tools.

🚀 Why Smart Decoder?

• Stop tab-switching to any jwt, base64 or timestamp converters
• Keep sensitive tokens & data private (100% local processing)
• Perfect companion for API debugging, Copilot/Cursor users, backend/frontend devs
• Smart auto-detection + beautiful JWT webview

✨ Key Features

• ✨ Smart auto-detection engine (JWT, Base64, Hex, Timestamp, etc.)
• 🎟️ Visual JWT inspector (WebView)
• 🔓 Base64 encode/decode (hover any text to preview result + click to apply).
• 🧪 Hex decode/encode available via hover as well. Both previews reuse the same executeTransform logic that powers the quick‑pick/commands, so adding new formats is just a matter of extending transforms.ts and updating the detector in the hover provider.
• 🧪 Hex encode/decode
• 🔗 URL encode/decode
• 🕒 Unix ↔ ISO date converter
• 🔐 MD5 / SHA256 hash generator

2. Press Ctrl + Shift + T (Win/Linux) / Cmd + Shift + T (macOS)
   or right-click → Smart Decoder: Quick Transform
