pub trait NewMac {
    type KeySize: ArrayLength<u8>;

[−] Expand description

Instantiate a Mac algorithm.

Associated Types

type KeySize: ArrayLength<u8>[−]

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

Required methods

pub fn new(key: &GenericArray<u8, Self::KeySize>) -> Self[−]

Initialize new MAC instance from key with fixed size.

Provided methods

pub fn new_varkey(key: &[u8]) -> Result<Self, InvalidKeyLength>[−]

Initialize new MAC instance from key with variable size.

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