pub struct HmacEngine<T: Hash> { /* private fields */ }

Expand description

Pair of underyling hash engines, used for the inner and outer hash of HMAC

Implementations

source

impl<T: Hash> HmacEngine<T>

source

pub fn new(key: &[u8]) -> HmacEngine<T> ⓘ

Construct a new keyed HMAC with the given key. We only support underlying hashes whose block sizes are ≤ 128 bytes; larger hashes will result in panics.

Trait Implementations
