A symmetric-key block cipher.

Required methods

fn encrypt(
    &self,
    builder: &mut GadgetBuilder<F>,
    key: &Expression<F>,
    input: &Expression<F>
) -> Expression<F>

Encrypt the given input using the given key.

fn decrypt(
    &self,
    builder: &mut GadgetBuilder<F>,
    key: &Expression<F>,
    output: &Expression<F>
) -> Expression<F>

Decrypt the given output using the given key.

Provided methods

fn encrypt_evaluate(&self, key: &Element<F>, input: &Element<F>) -> Element<F>

Like encrypt, but actually evaluates the encryption function rather than just adding it to a GadgetBuilder.

fn decrypt_evaluate(&self, key: &Element<F>, output: &Element<F>) -> Element<F>

Like decrypt, but actually evaluates the decryption function rather than just adding it to a GadgetBuilder.
