Trait cipher::NewBlockCipher[][src]

pub trait NewBlockCipher: Sized {
    type KeySize: ArrayLength<u8>;

Provided methods

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

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.
