Struct Rsa

pub struct Rsa<'d, Dm: DriverMode> { /* private fields */ }

Available on crate feature unstable only.

RSA peripheral container

Implementations

impl<Dm: DriverMode> Rsa<'_, Dm>

pub fn ready(&mut self) -> Result<(), Infallible>

After the RSA Accelerator is released from reset, the memory blocks needs to be initialized, only after that peripheral should be used. This function would return without an error if the memory is initialized

pub fn enable_disable_interrupt(&mut self, enable: bool)

Enables/disables rsa interrupt.

When enabled rsa peripheral would generate an interrupt when a operation is finished.

pub fn enable_disable_search_acceleration(&mut self, enable: bool)

Enables/disables search acceleration.

When enabled it would increases the performance of modular exponentiation by discarding the exponent’s bits before the most significant set bit.

Note: this might decrease security.

For more information refer to 18.3.4 of https://www.espressif.com/sites/default/files/documentation/esp32-c6_technical_reference_manual_en.pdf

pub fn enable_disable_constant_time_acceleration(&mut self, enable: bool)

Enables/disables constant time acceleration.

When enabled it would increases the performance of modular exponentiation by simplifying the calculation concerning the 0 bits of the exponent. I.e. lesser the hamming weight, greater the performance.

Note: this might decrease security.

impl<'d> Rsa<'d, Blocking>

pub fn new(rsa: impl Peripheral<P = RSA> + 'd) -> Self

Create a new instance in crate::Blocking mode.

Optionally an interrupt handler can be bound.

pub fn into_async(self) -> Rsa<'d, Async>

Reconfigures the RSA driver to operate in asynchronous mode.

pub fn set_interrupt_handler(&mut self, handler: InterruptHandler)

Registers an interrupt handler for the RSA peripheral.

Note that this will replace any previously registered interrupt handlers.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

impl<'d> Rsa<'d, Async>

pub fn into_blocking(self) -> Rsa<'d, Blocking>

Create a new instance in crate::Blocking mode.

fn set_interrupt_handler(&mut self, handler: InterruptHandler)
