Kryptix
Kryptix is a privacy-first desktop/mobile password generator that never stores or transmits your passwords. Using a deterministic algorithm, it derives unique, high-entropy passwords locally from a single master key and service name via 50,000 iterations of SHA-256 key stretching. It features biometric-protected master key storage, password versioning for seamless rotation, bilingual support (English/Arabic), and a responsive adaptive UI. The app runs fully offline with a zero-knowledge architecture — your master key never leaves your device.
