I built a hardware-bound local password vault hidden in a photo

BlindLock is a local password manager that encrypts sensitive data (passwords, notes, 2FA secrets) directly on your device and conceals it inside an ordinary PNG image file, requiring the correct carrier file, master password, and authorized device to access. The tool uses steganography and 256-bit encryption with post-quantum cryptography components to protect data, eliminating the risk of centralized server breaches since vault contents never leave your device. BlindLock offers a single tier of features including password management, built-in authenticator, encrypted file storage, and optional hardware security key support, with pricing starting at $49 for a lifetime license.
