Struct elastic_elgamal::CandidateDecryption

pub struct CandidateDecryption<G: Group> { /* private fields */ }

Candidate for a VerifiableDecryption that is not yet verified. This presentation should be used for decryption data retrieved from an untrusted source.

Decryption data can be verified using Self::verify(). The threshold encryption scheme implemented in the sharing module has its own verification procedure in PublicKeySet.

Examples

See VerifiableDecryption for an example of usage.

Implementations

impl<G: Group> CandidateDecryption<G>

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Deserializes decryption data from bytes. Returns None if the data is malformed.

pub fn verify(
    self,
    ciphertext: Ciphertext<G>,
    key: &PublicKey<G>,
    proof: &LogEqualityProof<G>,
    transcript: &mut Transcript
) -> Result<VerifiableDecryption<G>, VerificationError>

Verifies this as decryption for ciphertext under key using the provided zero-knowledge proof.

Errors

Returns an error if proof does not verify.

pub fn into_unchecked(self) -> VerifiableDecryption<G>

Converts this candidate decryption into a VerifiableDecryption without verifying it. This only semantically correct if the data was verified in some other way.

Trait Implementations

impl<G: Clone + Group> Clone for CandidateDecryption<G>

fn clone(&self) -> CandidateDecryption<G>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<G: Debug + Group> Debug for CandidateDecryption<G>

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

Formats the value using the given formatter.

impl<'de, G: Group> Deserialize<'de> for CandidateDecryption<G>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl<G: Group> From<VerifiableDecryption<G>> for CandidateDecryption<G>

fn from(decryption: VerifiableDecryption<G>) -> Self

Converts to this type from the input type.

impl<G: Group> Serialize for CandidateDecryption<G>

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

Serialize this value into the given Serde serializer.
