Trait aes::NewBlockCipher

pub trait NewBlockCipher {
    type KeySize: ArrayLength<u8>;
    fn new(key: &GenericArray<u8, Self::KeySize>) -> Self;

    fn new_from_slice(key: &[u8]) -> Result<Self, InvalidLength> { ... }
}

Instantiate a BlockCipher algorithm.

Associated Types

type KeySize: ArrayLength<u8>

Key size in bytes with which cipher guaranteed to be initialized.

Required methods

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

Create new block cipher instance from key with fixed size.

Provided methods

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

Create new block cipher instance from key with variable size.

Default implementation will accept only keys with length equal to KeySize, but some ciphers can accept range of key lengths.
