pub struct HmacEngine<T>where
T: Hash,{ /* private fields */ }
Expand description
Pair of underyling hash engines, used for the inner and outer hash of HMAC.
Implementations§
§impl<T> HmacEngine<T>where
T: Hash,
impl<T> HmacEngine<T>where T: Hash,
pub fn new(key: &[u8]) -> HmacEngine<T> ⓘ
pub fn new(key: &[u8]) -> HmacEngine<T> ⓘ
Constructs a new keyed HMAC from key
.
We only support underlying hashes whose block sizes are ≤ 128 bytes.
Panics
Larger hashes will result in a panic.
pub fn from_inner_engines(
iengine: <T as Hash>::Engine,
oengine: <T as Hash>::Engine
) -> HmacEngine<T> ⓘ
pub fn from_inner_engines( iengine: <T as Hash>::Engine, oengine: <T as Hash>::Engine ) -> HmacEngine<T> ⓘ
A special constructor giving direct access to the underlying “inner” and “outer” engines.
