Struct Hash 

pub struct Hash<'d, T: Instance, M: Mode> { /* private fields */ }

HASH driver.

Implementations

impl<'d, T: Instance> Hash<'d, T, Blocking>

pub fn new_blocking( peripheral: Peri<'d, T>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Instantiates, resets, and enables the HASH peripheral.

impl<'d, T: Instance, M: Mode> Hash<'d, T, M>

pub fn start<A, H: HmacMode<A>>( &mut self, format: DataType, key: Option<&[u8]>, ) -> Context<A, M, H>

where A: ContextBufferType<M> + AlgorithmSpec,

Starts computation of a new hash and returns the saved peripheral state.

pub fn update_blocking<A, H: HmacMode<A>>( &mut self, ctx: &mut Context<A, Blocking, H>, input: &[u8], )

where A: ContextBufferType<Blocking> + AlgorithmSpec,

Restores the peripheral state using the given context, then updates the state with the provided data. Peripheral state is saved upon return.

pub fn finish_blocking<A, H: HmacMode<A>>( &mut self, ctx: Context<A, Blocking, H>, digest: &mut [u8], ) -> usize

where A: ContextBufferType<Blocking> + AlgorithmSpec,

Computes a digest for the given context. The digest buffer must be large enough to accomodate a digest for the selected algorithm. The largest returned digest size is 128 bytes for SHA-512. Panics if the supplied digest buffer is too short.
