Shadow Vault – Zero-Knowledge Encrypted File Storage Platform
Description
Shadow Vault – Zero-Knowledge Encrypted File Storage Platform (Tor-Optimized, Go + Svelte, Monero Integration)
Shadow Vault is an advanced zero-knowledge encrypted file storage platform, designed for rapid deployment as a self-hosted service, with native compatibility for use over the Tor network. The system combines high-performance architecture with strong data protection mechanisms, enabling a fully functional and monetizable secure storage solution.
Live Demo (Tor Required)
A live demonstration instance is available at:
http://fyvqqsnckrthn6z3xfvothtwwxczoxzefoe2jf64kvxxs26cxzuneqad.onion
Note: This is a Tor (.onion) service and can only be accessed using Tor Browser.
Core Architecture & Security Design
The platform is built using Golang v1.22 for the backend and Svelte for the frontend, with a strong focus on operational security and memory handling.
Key security components include:
SQLCipher for encrypted database storage
Argon2id for secure password hashing
Direct use of mlock system calls to keep sensitive data (such as encryption keys) pinned in RAM and prevent swapping to disk
Aggressive memory sanitization via secure zeroing techniques
The system is designed as a zero-knowledge architecture, meaning that all user data is encrypted at rest and remains inaccessible in plaintext even to the server administrator.
Codebase & Documentation
Over 20,000 lines of fully commented code
Detailed documentation of security-critical components, including encryption workflows and memory management
Included technical whitepaper covering:
cryptographic handshake design
memory pinning logic
Docker-based deployment architecture
Deployment
Shadow Vault is designed for immediate deployment:
Full source code included
Pre-built Docker TAR image provided
Multi-stage hardened Docker builds
Option to deploy instantly without compilation
Dual Frontend System
To accommodate different user profiles, the platform includes two distinct interfaces:
1. Standard UI (Svelte-based)
Modern, responsive interface
Client-side validation (e.g., file size checks before upload)
Real-time upload progress indicators
2. Zero-JS Mode
Pure HTML/CSS interface
No JavaScript execution
Designed for environments with strict security settings (e.g., Tor “Safest” mode)
Eliminates client-side scripting attack vectors such as XSS
Monetization & Subscription System
The backend is designed to support recurring revenue models:
Tiered feature access configurable via settings
Ability to lock advanced features (e.g., failsafe mechanisms) behind paywalls
Native integration with monero-wallet-rpc:
Unique subaddress generation per user
Automatic payment detection
Instant unlocking of storage or premium features
Automatic fund sweeping to a cold wallet
Failsafe & Alert Mechanisms
Shadow Vault includes advanced automated response systems:
Dead Man’s Switch (DMS)
If a user fails to check in within a defined interval:
session keys are destroyed
stored files are wiped or rendered inaccessible
Notification System
Telegram integration (requires user interaction during setup to enable communication)
Email alerts sent via Tor-proxied SMTP relay
Canary Traps
Decoy files placed within the filesystem
Detection of unauthorized access or inspection attempts
Alerts triggered upon suspicious interaction
Security Model
No backdoors included in the codebase
Full transparency through source code availability
Data stored exclusively as encrypted blobs
Administrative access does not allow plaintext data visibility
What’s Included
Full Go + Svelte source code
Technical whitepaper
Hardened Docker build system (multi-stage)
Pre-compiled Docker TAR image for instant deployment
