Struct esp32c3_hal::hmac::Hmac

pub struct Hmac<'d> { /* private fields */ }

Implementations

impl<'d> Hmac<'d>

pub fn new( hmac: impl Peripheral<P = HMAC> + 'd, peripheral_clock_control: &mut PeripheralClockControl ) -> Hmac<'d>

pub fn free(self) -> PeripheralRef<'d, HMAC>

pub fn init(&mut self)

Step 1. Enable HMAC module.

Before these steps, the user shall set the peripheral clocks bits for HMAC and SHA peripherals and clear the corresponding peripheral reset bits.

pub fn configure( &mut self, m: HmacPurpose, key_id: KeyId ) -> Result<(), Error<Error>>

Step 2. Configure HMAC keys and key purposes.

pub fn update<'a>( &mut self, msg: &'a [u8] ) -> Result<&'a [u8], Error<Infallible>>

Process the msg block after block

Call this function as many times as necessary (msg.len() > 0)

pub fn finalize(&mut self, output: &mut [u8]) -> Result<(), Error<Infallible>>
