Uranium is a high-security storage vault for Large Language Model (LLM) weights, treating them as critical intellectual property that requires robust protection. Named after the radioactive element, Uranium emphasizes the careful handling required for these valuable assets - locked down with strong safeguards, yet accessible for legitimate use.

- Encrypted Storage: All model weights are encrypted at rest using ChaCha20-Poly1305 or AES-GCM
- Access Control: Role-based access control with JWT authentication
- Audit Logging: Comprehensive audit trail of all model access and operations
- Integrity Verification: Blake3 hashing ensures models haven't been tampered with
- Memory Protection: Optional memory locking to prevent model weights from being swapped to disk
- Session Management: Secure session handling with configurable timeouts
- Platform Security: macOS Keychain integration for secure master key storage
- Hardware Security: Secure Enclave detection and framework on Apple Silicon & T2 Macs with hardware-backed random generation
- Optimized Decryption: Streaming decryption with parallel processing
- Smart Caching: LRU cache for frequently accessed models
- Concurrent Access: Controlled concurrent model loading with semaphore protection
- Memory Efficient: Zero-copy operations where possible
- Simple CLI: Intuitive command-line interface for all operations
- Cross-Platform: Works on Windows, macOS, and Linux (optimized for macOS)
- Framework Agnostic: Compatible with PyTorch, TensorFlow, ONNX, and SafeTensors
- Minimal Overhead: Designed to add minimal latency to model loading
- $10M+ LLMs stored in plain files: Your proprietary models are sitting unencrypted on disk
- IP theft risk: One leaked model can destroy competitive advantage
- No audit trail: Can't tell who accessed your models or when
- Compliance nightmares: GDPR, SOC2, and other regulations require encryption at rest
Uranium provides bank-vault-level security for your AI assets:
# Without Uranium: Your $10M model is just a file
$ ls -la
-rw-r--r-- 1 user staff 13GB llama-70b-custom.safetensors # 😱 Unprotected!
# With Uranium: Military-grade protection (using demo API)

Master Key Management
- On macOS: Master keys are automatically stored in Keychain (hardware-backed when available)
- Use a hardware security module (HSM) or secure key management service on other platforms
- Never store the master key in plain text or configuration files
- Rotate keys regularly using the built-in key rotation features
-
Access Control
- Use strong passwords and consider multi-factor authentication
- Implement the principle of least privilege
- Regularly review and audit access logs
-
Network Security
- Always use TLS for API communication
- Consider running the vault on an isolated network
- Use firewall rules to restrict access
-
Operational Security
- Regular security audits
- Monitor for anomalous access patterns
- Have an incident response plan
Uranium automatically leverages macOS security features when available:
- Keychain Services: Master encryption keys are stored securely in the macOS Keychain
- Memory Protection: Uses
mlock()to prevent sensitive data from being swapped to disk - Secure Random: Hardware-backed random number generation via Security framework
- Secure Enclave: Hardware detection and secure random generation on Apple Silicon & T2 Macs
// Keys are automatically stored in Keychain on macOS
let platform = get_platform_security();
platform.store_hardware_key("vault_master", &master_key)?;
// Keys persist across application restarts
let key = platform.get_hardware_key("vault_master")?;On Apple Silicon Macs and Intel Macs with T2 chip, Uranium provides a foundation for Secure Enclave integration:
# Check if Secure Enclave is available
$ uranium security status
Platform Security Status:
✅ Secure Enclave: Available (Apple M2 Pro)
✅ Hardware detection: Active
✅ Random generation: Hardware-backed
✅ Memory protection: ActiveCurrent Implementation:
- Hardware Detection: Automatic detection of Secure Enclave availability on Apple Silicon and T2 Macs
- Hardware Random: SecRandomCopyBytes for cryptographically secure random number generation
- Framework Ready: API structure prepared for full Secure Enclave key generation and storage
- Enhanced Security: Uses hardware-backed randomness when available, software fallback otherwise
Future Development: Full ECIES encryption with hardware-isolated keys is planned for future releases, building on the current framework implementation.
