Trait aes::NewBlockCipher
pub trait NewBlockCipher: Sized {
type KeySize: ArrayLength<u8>;
fn new(key: &GenericArray<u8, Self::KeySize>) -> Self;
fn new_from_slice(key: &[u8]) -> Result<Self, InvalidLength> { ... }
}Expand description
Instantiate a BlockCipher algorithm.
Required 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_from_slice(key: &[u8]) -> Result<Self, InvalidLength>
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.
