Required Methods

fn encrypt_lwe_ciphertext_vector(
    &mut self,
    key: &SecretKey,
    input: &PlaintextVector,
    noise: Variance
) -> Result<CiphertextVector, LweCiphertextVectorEncryptionError<Self::EngineError>>

Encrypts an LWE ciphertext vector.

unsafe fn encrypt_lwe_ciphertext_vector_unchecked(
    &mut self,
