ADS ZONE (ACTIVE ONCE SERVE ID IS SET)
Inspect JWT tokens, calculate cryptographic hashes (SHA-256, MD5), generate HMAC signatures, and encode Base64 entirely in local browser RAM.
All parsing, decoding, and cryptographic signing run strictly inside your browser memory using native Web Crypto APIs.
Production JWTs, secret keys, and API tokens are never sent over the network to any server. Check DevTools Network tab.
Once loaded, the JWT Inspector and Cryptographic Hasher work completely offline without an active internet connection.
