Expand description

Types which can be initialized from key and initialization vector (nonce).

Required Methods§

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

Create new value from fixed length key and nonce.

Provided Methods§

fn new_from_slices(key: &[u8], iv: &[u8]) -> Result<Self, InvalidLength>

Create new value from variable length key and nonce.

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

Generate random key using the provided CryptoRng.

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

Generate random IV using the provided CryptoRng.

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

Generate random key and nonce using the provided CryptoRng.
