HmacContext

embassy_nrf::crypto::symmetric

Struct HmacContext 

Source 
pub struct HmacContext<A: HashAlgorithm> { /* private fields */ }
Expand description

State of an HMAC computation in progress. Created by Symmetric::hmac_start.

Implementations§

Source§

impl<A: HashAlgorithm> HmacContext<A>

Source

pub fn reset(&mut self)

Resets the context, keeping the key.

Afterwards the context is as if Symmetric::hmac_start had just returned it. This is cheaper than starting a new one, since the key does not have to be processed again.
