Native Web Crypto Signing
Signatures are calculated using browser-native HMAC-SHA256 implementations via window.crypto.subtle for hardware-level security.
Zero Cloud Key Retention
Your secret passphrases, customer IDs, and authorization tokens never leave your local device memory or browser sandbox.
Dynamic Timestamp Engine
Accurately computes relative iat (issued at) and exp (expiration) epoch numbers to mock production authentication conditions.
