Kyber512 - Docs

Kyber512 is the fastest variant in the Kyber family, offering NIST Level 1 security with excellent performance characteristics.

Security Level

Kyber512 provides:

NIST Security Level 1
Protection against quantum computers with ~1000 qubits
Balanced security-performance trade-off
Ideal for high-frequency operations

Master Phrase Security

Your master encryption phrase is critical for data access. If lost, your encrypted files cannot be recovered. We strongly recommend using ByteHide Secrets for secure phrase management.

See our Zero-Knowledge Encryption guide for detailed information.

Implementation

// Initialize with secure key management
var secrets = new SecretsManager("<secrets_token>");
string masterPhrase = await secrets.Get("storage_master_phrase");

var storage = new StorageManager(
    "<token>", 
    masterPhrase,
    quantumAlgorithm: QuantumAlgorithmType.Kyber512
);

// Use in operations
await storage
    .EncryptWithQuantum()
    .Set("data.dat", sensitiveData);

Performance Characteristics

Key Generation: ~50μs
Encapsulation: ~60μs
Decapsulation: ~50μs
Public Key Size: 800 bytes
Secret Key Size: 1632 bytes
Ciphertext Size: 768 bytes

Use Cases

Ideal for:

High-frequency file operations
Mobile applications
Edge computing scenarios
Real-time data processing

Performance vs Security

Kyber512 offers the best performance in the Kyber family but with a lower security level. For highly sensitive data, consider Kyber1024.

Best Practices

Key Management
- Use ByteHide Secrets for master phrase storage
- Never hardcode the phrase in your code
- Implement proper key rotation procedures
- Keep secure backups of your master phrase
Implementation
- Enable quantum protection for all sensitive operations
- Consider caching for frequently accessed files
- Monitor performance metrics in your specific use case
- Document your security requirements and choices
