[+] Show declaration

pub trait NewBlockCipher: Sized {

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

[−] Expand description

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: &Key<Self>) -> Self[−]

Create new block cipher instance from key with fixed size.

Provided methods

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.
