Organize your sensitive information into isolated vaults, each secured with its own unique encryption key. This compartmentalized approach prevents data exposure between vaults even if one is compromised.

Data Encryption
Each record encrypted with vault's unique DEK using AES-256-GCM
Each vault has its own unique Data Encryption Key (DEK) derived from your master password. Records within a vault are encrypted using this DEK with AES-256-GCM, ensuring both confidentiality and integrity of your data.

Your master password and encryption keys never leave your device. Even if our servers are compromised, your data remains secure because it's encrypted with keys that only exist on your device.
How It Works
Vaulty ensures your passwords stay secure through strong cryptographic techniques, local-first architecture, and a privacy-focused design. Here's how:
Create Your Vault
Initialize your personal vault by choosing a strong master password. This password is never stored or transmitted. Internally, we derive a secure encryption key using a key derivation function (KDF) like Argon2 or PBKDF2 — these are resistant to brute-force and dictionary attacks by design. The derived key is used to encrypt all your stored secrets locally.
Client-Side Encryption
All cryptographic operations—encryption, decryption, key derivation—happen entirely on your device. We use modern, vetted algorithms like AES-256-GCM for authenticated encryption, ensuring both confidentiality and integrity. No plaintext data or raw keys are ever sent or exposed to our servers.
Secure Storage
Only the encrypted vault file is transmitted and stored on our backend. This ciphertext is meaningless without your master password. Since encryption happens before sync, even if our server is compromised, your data remains unreadable. We use checksums and HMACs to detect any tampering attempts.
Command Line Access
Vaulty is built for developers and power users. With intuitive CLI commands like vaulty add, vaulty get, and vaulty search, you can manage credentials directly from the terminal. Advanced filters, tag support, and fuzzy searching make it fast to locate secrets. Vaulty respects the UNIX philosophy: simple, scriptable, and composable.
Secure Sync Across Devices
Your encrypted vault is automatically synchronized across your authorized devices. Each sync uses end-to-end encryption, and device authorization is protected with public-private key cryptography (e.g., using Ed25519). This ensures only your devices can decrypt the vault, even during transport.
Frequently Asked Questions
Is Vaulty really secure?
Yes! We use strong client-side encryption to ensure your data is protected. All encryption and decryption happens on your device, so your plaintext passwords never leave your computer. We follow a zero-knowledge architecture where we never see or store your actual passwords.
Why use a command-line password manager?
Command-line tools offer unparalleled efficiency and automation capabilities. For developers and power users, managing passwords through the terminal is faster, more scriptable, and integrates better with existing workflows. Vaulty brings security and simplicity together in your familiar terminal environment.
Is there a GUI version available?
Vaulty is designed specifically as a command-line tool for users who prefer that interface. We focus on making the CLI experience as smooth as possible rather than developing a GUI alternative.
What platforms does Vaulty support?
Vaulty works on Windows, macOS, and Linux. Since it's built with cross-platform compatibility in mind, the experience and features are consistent across all operating systems.
Can I import passwords from other managers?
Yes. Vaulty supports importing from CSV files and directly from several popular password managers. You can easily migrate your existing passwords without manual re-entry.
What happens if I forget my master password?
Due to Vaulty's security architecture, we cannot recover your master password if you forget it. However, Vaulty supports optional recovery methods that you can set up, such as a recovery phrase that you should store in a secure location.
Is Vaulty open source?
Yes. We believe in transparency and community review. Vaulty's CLI client source code is publicly available on GitHub, allowing security experts to verify our implementation and contribute improvements.
