Struct DecryptionKey 

pub struct DecryptionKey<P>
where
    P: PkeParams,
{
    s_hat: NttVector<P::K>,
}

A DecryptionKey provides the ability to generate a new key pair, and decrypt an encrypted value.

Fields

s_hat: NttVector<P::K>

Implementations

impl<P> DecryptionKey<P>

where P: PkeParams,

pub fn generate(d: &B32) -> (Self, EncryptionKey<P>)

Generate a new random decryption key according to the K-PKE.KeyGen procedure.

pub fn decrypt( &self, ciphertext: &Array<u8, <P as PkeParams>::CiphertextSize>, ) -> B32

Decrypt ciphertext to obtain the encrypted value, according to the K-PKE.Decrypt procedure.

pub fn as_bytes(&self) -> Array<u8, <P as PkeParams>::NttVectorSize>

Represent this decryption key as a byte array (s_hat)

pub fn from_bytes(enc: &Array<u8, <P as PkeParams>::NttVectorSize>) -> Self

Parse an decryption key from a byte array (s_hat)

Trait Implementations

impl<P> Clone for DecryptionKey<P>

where P: PkeParams + Clone, P::K: Clone,

fn clone(&self) -> DecryptionKey<P>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<P> Debug for DecryptionKey<P>

where P: PkeParams + Debug, P::K: Debug,

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

Formats the value using the given formatter.

impl<P> Default for DecryptionKey<P>

where P: PkeParams + Default, P::K: Default,

fn default() -> DecryptionKey<P>

Returns the “default value” for a type.

impl<P> PartialEq for DecryptionKey<P>

where P: PkeParams + PartialEq, P::K: PartialEq,

fn eq(&self, other: &DecryptionKey<P>) -> 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<P> StructuralPartialEq for DecryptionKey<P>
