How It Works

Data is encrypted with AES-256-CBC + HMAC-SHA256 and stored in ~/.config/jkey/:

~/.config/jkey/
├── .session          # Session cache (5 min timeout)
├── totp.jkey         # Encrypted TOTP secrets
├── passwords.jkey    # Encrypted passwords
├── recovery.jkey     # Encrypted recovery codes
└── qr/               # Encrypted QR images

Back up ~/.config/jkey/ (excluding .session) to migrate to another machine.

Dependencies

• opencv-python-headless — QR code scanning

Pure Python, no OpenSSL or libsodium required.
