Struct RsaMultiplication

pub struct RsaMultiplication<'a, 'd, T: RsaMode + Multi, Dm: DriverMode> { /* private fields */ }

Available on crate feature unstable only.

Support for RSA peripheral’s large number multiplication feature that could be used to find the operand a * operand b.

Each operand is a little endian byte array of the same size

Implementations

impl<T, const N: usize> RsaMultiplication<'_, '_, T, Async>

where T: RsaMode<InputType = [u32; N]> + RsaMode + Multi,

pub async fn multiplication<const O: usize>( &mut self, operand_b: &T::InputType, outbuf: &mut T::OutputType, )

where T: Multi<OutputType = [u32; O]>,

Asynchronously performs an RSA multiplication operation.

impl<'a, 'd, T, Dm: DriverMode, const N: usize> RsaMultiplication<'a, 'd, T, Dm>

where T: RsaMode<InputType = [u32; N]> + RsaMode + Multi,

pub fn new(rsa: &'a mut Rsa<'d, Dm>, operand_a: &T::InputType) -> Self

Creates an instance of RsaMultiplication.

pub fn start_multiplication(&mut self, operand_b: &T::InputType)

Starts the multiplication operation.

pub fn read_results<const O: usize>(&mut self, outbuf: &mut T::OutputType)

where T: Multi<OutputType = [u32; O]>,

Reads the result to the given buffer. This is a non blocking function that returns without an error if operation is completed successfully. start_multiplication must be called before calling this function.
