Struct EncryptionKey 

pub struct EncryptionKey<P>
where
    P: PkeParams,
{
    t_hat: NttVector<P::K>,
    rho: B32,
}

An EncryptionKey provides the ability to encrypt a value so that it can only be decrypted by the holder of the corresponding decapsulation key.

Fields

t_hat: NttVector<P::K>

rho: B32

Implementations

impl<P> EncryptionKey<P>

where P: PkeParams,

pub fn encrypt( &self, message: &B32, randomness: &B32, ) -> Array<u8, <P as PkeParams>::CiphertextSize>

Encrypt the specified message for the holder of the corresponding decryption key, using the provided randomness, according the K-PKE.Encrypt procedure.

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

Represent this encryption key as a byte array (t_hat || rho)

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

Parse an encryption key from a byte array (t_hat || rho)

Trait Implementations

impl<P> Clone for EncryptionKey<P>

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

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<P> Debug for EncryptionKey<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 EncryptionKey<P>

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

fn default() -> EncryptionKey<P>

Returns the “default value” for a type.

impl<P> PartialEq for EncryptionKey<P>

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

fn eq(&self, other: &EncryptionKey<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 EncryptionKey<P>
