Trait crypto_mac::NewMac [−][src]
pub trait NewMac: Sized { type KeySize: ArrayLength<u8>; fn new(key: &Key<Self>) -> Self; fn new_from_slice(key: &[u8]) -> Result<Self, InvalidKeyLength> { ... } }
Expand description
Instantiate a Mac
algorithm.
Associated Types
type KeySize: ArrayLength<u8>
type KeySize: ArrayLength<u8>
Key size in bytes with which cipher guaranteed to be initialized.
Required methods
Provided methods
fn new_from_slice(key: &[u8]) -> Result<Self, InvalidKeyLength>
fn new_from_slice(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.
Implementors
impl<T> NewMac for T where
T: FromBlockCipher,
T::Cipher: NewBlockCipher,
This is supported on crate feature
cipher
only.
