MLKEM768 - Docs

MLKEM768 is the balanced variant of the ML-KEM family, providing NIST Level 3 security with an excellent balance between security and performance.

Security Level

MLKEM768 provides:

NIST Security Level 3
Advanced lattice-based security
Strong resistance to quantum attacks
Balanced performance-security trade-off

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.MLKEM768
);

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

Performance Characteristics

Key Generation: ~75μs
Encapsulation: ~85μs
Decapsulation: ~75μs
Public Key Size: 1088 bytes
Secret Key Size: 2304 bytes
Ciphertext Size: 1024 bytes

Use Cases

Ideal for:

Enterprise applications
Cloud storage solutions
Financial services
Healthcare data protection

Balanced Security

MLKEM768 provides a strong balance between security and performance, making it suitable for most enterprise applications. For maximum security, consider MLKEM1024.
