🔐 Zero-Knowledge Architecture
LocalKey is built on a zero-knowledge architecture where your data is encrypted locally on your device. We cannot access, view, or decrypt your passwords - even if we wanted to. Your security is guaranteed by design, not just by policy.
🔒 Encryption Standards
Military-Grade Encryption
🔐 AES-256 Encryption
Advanced Encryption Standard with 256-bit keys - the same encryption used by banks, governments, and military organizations worldwide.
🔑 PBKDF2 Key Derivation
Password-Based Key Derivation Function 2 with 100,000+ iterations and SHA-256 hashing for maximum key security.
🛡️ Secure Random Generation
Cryptographically secure random number generation for passwords, salts, and encryption keys using OS-level entropy sources.
🏗️ Security Architecture
Application Security
- Process Isolation: Complete separation between main process and renderer for maximum security
- Context Isolation: No Node.js access in renderer process prevents code injection
- Sandboxing: Renderer processes run in restricted sandbox environment
- Content Security Policy: Strict CSP prevents XSS and code injection attacks
- Memory Protection: Sensitive data cleared from memory after use
Data Protection
- Local Storage Only: All data stored locally on your device, never in the cloud
- Encrypted at Rest: Vault files encrypted with AES-256 when stored on disk
- Encrypted in Memory: Sensitive data encrypted even in RAM
- Secure Deletion: Military-grade data wiping when deleting sensitive information
- Backup Encryption: Backup files use the same encryption as your main vault
