Struct CrtClientKey 

pub struct CrtClientKey { /* private fields */ }

Client key “specialized” for CRT decomposition.

This key is a simple wrapper of the ClientKey, that only encrypt and decrypt in CRT decomposition.

Example

use tfhe::integer::CrtClientKey;
use tfhe::shortint::parameters::PARAM_MESSAGE_3_CARRY_3_KS_PBS_GAUSSIAN_2M128;

let basis = vec![2, 3, 5];
let cks = CrtClientKey::new(PARAM_MESSAGE_3_CARRY_3_KS_PBS_GAUSSIAN_2M128, basis);

let msg = 13_u64;

// Encryption:
let ct = cks.encrypt(msg);

// Decryption:
let dec = cks.decrypt(&ct);
assert_eq!(msg, dec);

Implementations

impl CrtClientKey

pub fn new<P>(parameters: P, moduli: Vec<u64>) -> Self

where P: Into<PBSParameters>,

pub fn encrypt(&self, message: u64) -> CrtCiphertext

pub fn encrypt_native_crt(&self, message: u64) -> CrtCiphertext

pub fn decrypt(&self, ciphertext: &CrtCiphertext) -> u64

pub fn decrypt_native_crt(&self, ciphertext: &CrtCiphertext) -> u64

pub fn parameters(&self) -> AtomicPatternParameters

Returns the parameters used by the client key.

pub fn moduli(&self) -> &[u64]

Trait Implementations

impl AsRef<ClientKey> for CrtClientKey

fn as_ref(&self) -> &ClientKey

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for CrtClientKey

fn clone(&self) -> CrtClientKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrtClientKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CrtClientKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<(ClientKey, Vec<u64>)> for CrtClientKey

fn from((key, moduli): (ClientKey, Vec<u64>)) -> Self

Converts to this type from the input type.

impl PartialEq for CrtClientKey

fn eq(&self, other: &CrtClientKey) -> 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 CrtClientKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Unversionize for CrtClientKey

where CrtClientKeyVersions: VersionsDispatch<Self>,

fn unversionize( versioned: Self::VersionedOwned, ) -> Result<Self, UnversionizeError>

Creates an object from a versioned enum, and eventually upgrades from previous variants.

impl UnversionizeVec for CrtClientKey

where CrtClientKeyVersions: VersionsDispatch<Self>,

fn unversionize_vec( versioned: Self::VersionedVec, ) -> Result<Vec<Self>, UnversionizeError>

impl Version for CrtClientKey

where ClientKey: VersionizeOwned + Unversionize + Versionize, Vec<u64>: VersionizeOwned + Unversionize + Versionize,

type Ref<'vers> = CrtClientKeyVersion<'vers>

type Owned = CrtClientKeyVersionOwned

impl Versionize for CrtClientKey

where CrtClientKeyVersions: VersionsDispatch<Self>,

type Versioned<'vers> = <CrtClientKeyVersions as VersionsDispatch<CrtClientKey>>::Ref<'vers>

The equivalent versioned type. It should have a variant for each version. It may own the underlying data or only hold a read-only reference to it.

fn versionize(&self) -> Self::Versioned<'_>

Wraps the object into a versioned enum with a variant for each version. This will use references on the underlying types if possible.

impl VersionizeOwned for CrtClientKey

where CrtClientKeyVersions: VersionsDispatch<Self>,

type VersionedOwned = <CrtClientKeyVersions as VersionsDispatch<CrtClientKey>>::Owned

fn versionize_owned(self) -> Self::VersionedOwned

Wraps the object into a versioned enum with a variant for each version. This will clone the underlying types.

impl VersionizeSlice for CrtClientKey

where CrtClientKeyVersions: VersionsDispatch<Self>,

type VersionedSlice<'vers> = Vec<<CrtClientKey as Versionize>::Versioned<'vers>>

fn versionize_slice(slice: &[Self]) -> Self::VersionedSlice<'_>

impl VersionizeVec for CrtClientKey

where CrtClientKeyVersions: VersionsDispatch<Self>,

type VersionedVec = Vec<<CrtClientKey as VersionizeOwned>::VersionedOwned>

fn versionize_vec(vec: Vec<Self>) -> Self::VersionedVec

impl VersionsDispatch<CrtClientKey> for CrtClientKeyVersions

where CrtClientKey: Version,

type Ref<'vers> = CrtClientKeyVersionsDispatch<'vers>

type Owned = CrtClientKeyVersionsDispatchOwned
