Expand description
Instantiate a BlockCipher
algorithm.
Associated Types
type KeySize: ArrayLength<u8>
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
fn new(key: &GenericArray<u8, Self::KeySize>) -> Self
Create new block cipher instance from key with fixed size.
Provided methods
fn new_varkey(key: &[u8]) -> Result<Self, InvalidKeyLength>
fn new_varkey(key: &[u8]) -> Result<Self, InvalidKeyLength>
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.
