IronDome 2.2.0

Iron Dome - A secure CLI password manager with AES-256 encryption and zero-knowledge architecture

Fortified CLI Password Manager — AES-256 | Zero-Knowledge | Hardware-Bound

Quick Start • Features • Security • Developers • Contributing

---

Your passwords. Your machine. Your rules.

IronDome encrypts everything locally with AES-256, binds keys to your hardware, and operates on a zero-knowledge model — your master password is never stored. Nothing leaves your device. Ever.

Quick Start

pip install IronDome

bunker

On first launch, choose your security level:

• Biometric Only (Touch ID / Windows Hello / Fingerprint)
• Biometric + Master Password (two-factor)
• Master Password Only (traditional)

Two commands. You're protected.

Biometric Authentication

IronDome integrates with the native biometric stack on each platform — no third-party biometric services, no data transmitted.

Supported Platforms

Platform	Mechanism	Requirement
macOS	Touch ID (LocalAuthentication framework)	Touch ID sensor or Apple Watch
Windows	Windows Hello (PIN, fingerprint, face)	Windows Hello-compatible hardware
Linux	fprintd (fingerprint daemon)	Supported fingerprint reader + fprintd installed

Biometric is optional. If hardware is unavailable, IronDome falls back to Master Password Only mode automatically.

Two Modes

Biometric Only — A cryptographically random vault key is generated at setup and stored in the OS credential store (Keychain on macOS, Windows Credential Manager, libsecret on Linux). Biometric proof unlocks the credential store; the vault key never touches disk unprotected.

Biometric + Master Password — Biometric is a gate, not the key. A successful biometric check permits password entry; PBKDF2 still derives the vault key from your master password. This is the higher-assurance mode — compromising biometrics alone is not sufficient to decrypt the vault.

Recovery Key

When you enroll biometrics, IronDome generates a one-time 24-word recovery phrase (BIP-39 format). Write it down and store it offline. It is the only way to recover the vault if biometric hardware fails or is replaced. IronDome does not store the recovery key.

Re-authentication

Session re-authentication for sensitive operations (delete, export, backup) uses the same method you enrolled with. If you enrolled with Biometric + Master Password, both factors are required for re-authentication.
