A trait for engines encrypting (discarding) LWE ciphertexts.

Semantics

This discarding operation fills the output LWE ciphertext with the encryption of the input plaintext, under the key secret key.

Required Methods

fn discard_encrypt_lwe_ciphertext(
    &mut self,
    key: &SecretKey,
    output: &mut Ciphertext,
    input: &Plaintext,
    noise: Variance
) -> Result<(), LweCiphertextDiscardingEncryptionError<Self::EngineError>>

Encrypts an LWE ciphertext.

unsafe fn discard_encrypt_lwe_ciphertext_unchecked(
    &mut self,
    key: &SecretKey,
    output: &mut Ciphertext,
    input: &Plaintext,
    noise: Variance
)

Unsafely encrypts an LWE ciphertext.
