Executive Summary
RacterVault is a quantum-ready, zero-knowledge encrypted cloud storage platform with integrated digital succession planning. This whitepaper provides a comprehensive technical overview of our security architecture, cryptographic implementations, and threat model.
Key Security Features
- Zero-Knowledge Architecture: Client-side encryption ensures we never have access to user data or keys
- Quantum-Resistant Cryptography: Hybrid classical + post-quantum algorithms protect against future threats
- Icelandic Jurisdiction: Data stored outside 14-Eyes surveillance alliance with strong privacy laws
- Automated Succession: Cryptographically secure key escrow for digital legacy planning
- End-to-End Encryption: All data encrypted before leaving user devices
Target Audience: Security researchers, privacy advocates, enterprise security teams, and technical users evaluating RacterVault for sensitive data storage.
