Struct Rsa 

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

RSA peripheral driver.

Implementations

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

pub fn new(rsa: RSA<'d>) -> Self

Create a new instance in 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 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 set_interrupt_handler(&mut self, handler: InterruptHandler)

Available on crate feature unstable only.

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.

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

pub fn disable_constant_time(&mut self, disable: bool)

Enables/disables constant time operation.

Disabling constant time operation increases the performance of modular exponentiation by simplifying the calculation concerning the 0 bits of the exponent. I.e. the less the Hamming weight, the greater the performance.

Note: this compromises security by enabling timing-based side-channel attacks.

For more information refer to the Technical Reference Manual

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

Enables/disables search acceleration.

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

Note: this compromises security by effectively decreasing the key length.
