Trait crypto_mac::NewMac

pub trait NewMac: Sized {
    type KeySize: ArrayLength<u8>;
    fn new(key: &Key<Self>) -> Self;

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

Instantiate a Mac 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

Initialize new MAC instance from key with fixed size.

Provided methods

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.
