A trait for engines decrypting (discarding) GLWE ciphertexts.

Semantics

This discarding operation fills the output plaintext vector with the decryption of the input GLWE ciphertext, under the key secret key.

Required Methods

fn discard_decrypt_glwe_ciphertext(
    &mut self,
    key: &SecretKey,
    output: &mut PlaintextVector,
    input: &Ciphertext
) -> Result<(), GlweCiphertextDiscardingDecryptionError<Self::EngineError>>

Decrypts a GLWE ciphertext .

unsafe fn discard_decrypt_glwe_ciphertext_unchecked(
    &mut self,
    key: &SecretKey,
    output: &mut PlaintextVector,
    input: &Ciphertext
)

Unsafely decrypts a GLWE ciphertext .
