Trait aes_gcm::NewAead

pub trait NewAead {
    type KeySize: ArrayLength<u8>;

    // Required method
    fn new(key: &GenericArray<u8, Self::KeySize>) -> Self;

    // Provided methods
    fn new_from_slice(key: &[u8]) -> Result<Self, Error>
       where Self: Sized { ... }
    fn generate_key(
        rng: impl CryptoRng + RngCore
    ) -> GenericArray<u8, Self::KeySize> { ... }
}

Instantiate either a stateless Aead or stateful AeadMut algorithm.

Required Associated Types

type KeySize: ArrayLength<u8>

The size of the key array required by this algorithm.

Required Methods

fn new(key: &GenericArray<u8, Self::KeySize>) -> Self

Create a new AEAD instance with the given key.

Provided Methods

fn new_from_slice(key: &[u8]) -> Result<Self, Error>where Self: Sized,

Create new AEAD instance from key given as a byte slice..

Default implementation will accept only keys with length equal to KeySize.

fn generate_key( rng: impl CryptoRng + RngCore ) -> GenericArray<u8, Self::KeySize>

Generate a random key for this AEAD using the provided CryptoRng.

Implementors

type KeySize = <Aes as NewBlockCipher>::KeySize
