Trait scicrypt::cryptosystems::DecryptDirectly

pub trait DecryptDirectly {
    type Plaintext;
    type Ciphertext;
    type SecretKey;
    fn decrypt_direct(
        ciphertext: &Self::Ciphertext, 
        secret_key: &Self::SecretKey
    ) -> Self::Plaintext;
}

Some cryptosystems do not require the public key to decrypt, as all the necessary information is stored within the ciphertext and the secret key. For example, ElGamal when its group is hard-coded.

Associated Types

type Plaintext

The type of the plaintexts to be encrypted.

type Ciphertext

The type of the encrypted plaintexts.

type SecretKey

The type of the decryption key.

Required methods

fn decrypt_direct(
    ciphertext: &Self::Ciphertext,
    secret_key: &Self::SecretKey
) -> Self::Plaintext

Decrypt a ciphertext using the secret key directly, without requiring a rich ciphertext.
