Struct QuantumKeypair 

pub struct QuantumKeypair {
    pub algorithm: QuantumAlgorithm,
    pub public_key: Vec<u8>,
    pub created_at: SystemTime,
    pub expires_at: Option<SystemTime>,
    /* private fields */
}

Quantum-safe keypair for signing authorization tuples

Fields

algorithm: QuantumAlgorithm

Algorithm used for this keypair

public_key: Vec<u8>

Public key (shareable)

created_at: SystemTime

Key creation timestamp

expires_at: Option<SystemTime>

Key expiration (recommended: 90 days)

Implementations

impl QuantumKeypair

pub fn generate() -> Result<Self>

Generate a new quantum-safe keypair

Security

Uses system entropy for key generation. In production, ensure:

• Sufficient entropy pool (/dev/urandom on Linux)
• Hardware RNG if available (RDRAND on modern CPUs)

pub fn generate_with_algorithm(algorithm: QuantumAlgorithm) -> Result<Self>

Generate keypair with specific algorithm

pub fn sign(&self, data: &[u8]) -> Result<QuantumSignature>

Sign data with quantum-safe algorithm

Arguments

• data - Data to sign (e.g., serialized RelationTuple)

Returns

Digital signature resistant to quantum attacks

pub fn verify(&self, data: &[u8], signature: &QuantumSignature) -> Result<bool>

Verify a quantum-safe signature

Arguments

• data - Original data that was signed
• signature - Signature to verify

Returns

true if signature is valid, false otherwise

pub fn needs_rotation(&self) -> bool

Check if key needs rotation
