Struct elastic_elgamal::CiphertextWithValue

pub struct CiphertextWithValue<G: Group, V: Zeroize = <G as ScalarOps>::Scalar> { /* private fields */ }

ElGamal Ciphertext together with fully retained information about the encrypted value and randomness used to create the ciphertext.

This type can be used to produce certain kinds of proofs, such as SumOfSquaresProof.

Implementations

impl<G: Group, V> CiphertextWithValue<G, V>

where V: Copy + Zeroize, G::Scalar: From<V>,

pub fn new<R: CryptoRng + RngCore>( value: V, receiver: &PublicKey<G>, rng: &mut R ) -> Self

Encrypts a value for the specified receiver.

This is a lower-level operation compared to PublicKey::encrypt() and should be used if the resulting ciphertext is necessary to produce proofs.

pub fn generalize(self) -> CiphertextWithValue<G>

Converts the enclosed value into a scalar.

impl<G: Group, V> CiphertextWithValue<G, V>

where V: Zeroize, G::Scalar: From<V>,

pub fn inner(&self) -> &Ciphertext<G>

Returns a reference to the contained Ciphertext.

Trait Implementations

impl<G: Debug + Group, V: Debug + Zeroize> Debug for CiphertextWithValue<G, V>

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

Formats the value using the given formatter.

impl<G: Group, V: Zeroize> From<CiphertextWithValue<G, V>> for Ciphertext<G>

fn from(ciphertext: CiphertextWithValue<G, V>) -> Self

Converts to this type from the input type.
