Enum CryptoSuite 

#[repr(u8)]
pub enum CryptoSuite {
    PqHybrid = 1,
    Classical = 2,
}

Cryptographic suite identifier carried in the ZCP envelope header.

This tells the receiver how to interpret the encrypted payload and MAC. The actual crypto operations are performed by the consuming implementation, not by clonic.

Variants

PqHybrid = 1

Post-quantum hybrid: ML-KEM-768 + X25519 key exchange, ML-DSA-65 + Ed25519 signatures, AES-256-GCM symmetric.

Used on Linux devices with >= 1 GB RAM. Provides defense against both classical and quantum-era attacks.

Classical = 2

Classical-only: X25519 key exchange, Ed25519 signatures, AES-256-GCM symmetric.

Used on constrained devices (ESP32, STM32, nRF52). ML-KEM/ML-DSA are too expensive for sub-MHz microcontrollers.

Implementations

impl CryptoSuite

pub const fn from_byte(b: u8) -> Option<CryptoSuite>

Try to interpret a raw byte as a known crypto suite.

pub const fn as_byte(self) -> u8

Return the raw byte representation.

pub const fn is_post_quantum(self) -> bool

Whether this suite includes post-quantum key exchange.

Trait Implementations

impl Clone for CryptoSuite

fn clone(&self) -> CryptoSuite

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CryptoSuite

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CryptoSuite

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for CryptoSuite

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CryptoSuite

fn eq(&self, other: &CryptoSuite) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CryptoSuite

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for CryptoSuite
