Sovereign Encryption Node

Hardened Architecture

A Fortress on Your Phone

By shifting password storage entirely to local physical chips, Secure Vault provides an impenetrable wall against remote breaches, database leaks, and state actors.

Zero-Knowledge

PURELY LOCAL MEMORY

We possess zero cloud databases, zero telemetry pipelines, and zero sync structures. Your database keys are completely hidden from us.

AES-256-GCM

HARDWARE KEYSTORE

Every record block uses standardized Advanced Encryption Standard in Galois/Counter Mode. Keys are derived strictly through Argon2.

Passphrase Gen

ENTROPY ENGINE

Deploy local entropy loops to spit out massive 64-character master keys, custom symbols blocks, and high complexity codes in milliseconds.

Backup Blocks

COLD STORAGE

Compile your local secure store into heavily compiled JSON files. Transfer locally via physical USB keys, local SD drives, or Bluetooth pairings.

Cryptographic Design

Strict Zero-Knowledge

Secure Vault operates under a strict offline-first protocol. No third-party servers exist, and the application does not contain code to communicate over the web. This guarantees your database never leaks, but places total sovereignty in your hands.

SOVEREIGN WARNING NOTICE

If you forget your master password, your records are physically unrecoverable. We hold zero decryption capabilities. Your secrets are yours alone.

LOCAL CRYPTO WORKFLOW (ARGON2 + AES-256-GCM)

1. Derive Master Key

Your Master Password is fed into a hardware-bound Argon2 parameter loop. Wipes pure text from RAM blocks immediately.

2. Generate Cipher Key

Android Keystore binds the derived cryptographic variables to device-specific processors (TrustZone / Secure Element).

3. Perform Encrypted Write

Data blocks are encrypted with AES-256-GCM. Unencrypted database records never touch the physical disk sectors.

Common Questions

Frequently Asked Questions

Everything you need to know about our local database structures, zero-knowledge architecture, and cryptographic protocols.

Your passwords are stored locally inside an encrypted database on your Android device. It uses AES-256-GCM encryption. The encryption keys are derived dynamically from your Master Password using Argon2 / PBKDF2. For added security, we bind cryptographic variables to Android's hardware-backed Keystore system.
Because Secure Vault is 100% offline and zero-knowledge, your master password is never stored on any server or inside the application files. If you lose your master password, your passwords cannot be recovered under any circumstances. There are no support backdoors, no password reset emails, and no recovery keys.
No! Secure Vault does not request 'android.permission.INTERNET' inside its AndroidManifest.xml configuration. This means the Android operating system strictly blocks any network outbound or inbound traffic for the app. It is mathematically and physically impossible for the app to leak credentials to the internet.
You can navigate to the 'Security Dials' settings screen and click 'Generate Encrypted Backup Block'. This compiles your entire credential vault into a highly secure, AES-encrypted JSON file. You can transfer this block file manually (via USB drive, local SD card, or local pairing) to your new phone and upload it under 'Secure Restore' using your same Master Password.
Yes! We believe security software must be entirely transparent. The entire codebase is open-source and open for public cryptographic audits. This ensures there are no backdoor channels, hidden telemetry, or tracking SDKs installed.
