RSA Accelerator support.

Overview

The RSA driver provides a set of functions to accelerate RSA (Rivest–Shamir–Adleman) cryptographic operations on ESP chips. RSA is a widely used public-key cryptographic algorithm that involves complex mathematical computations, and the RSA accelerator on ESP chips is designed to optimize these computations for faster performance.

Implementation details;

  • The driver uses low-level peripheral access to read and write data from/to the RSA peripheral.
  • The driver contains unsafe code blocks as it directly manipulates memory addresses for data transfer.
  • The driver supports different sizes of operands based on the generic types provided during instantiation.
  • The nb crate is used to handle non-blocking operations.
  • The driver provides a set of high-level abstractions to simplify RSA cryptographic operations on ESP chips, allowing developers to leverage the RSA accelerator for improved performance.

Examples

Initialization

let peripherals = Peripherals::take();
let mut system = peripherals.PCR.split();

let mut rsa = Rsa::new(peripherals.RSA, &mut system.peripheral_clock_control);

⚠️: The examples for RSA peripheral are quite extensive, so for a more detailed study of how to use this driver please visit the repository with corresponding example.
