Module esp32_hal::rsa

RSA Accelerator support.

This module provides functions and structs for multi precision arithmetic operations used in RSA asym-metric cipher algorithms

Features

The RSA peripheral supports maximum operand of the following sizes for each individual chips:

Feature	ESP32	ESP32-C3	ESP32-C6	ESP32-S2	ESP32-S3
modular exponentiation	4096	3072	3072	4096	4096
modular multiplication	4096	3072	3072	4096	4096
multiplication	2048	1536	1536	2048	2048

Modules

• operand_sizes
  Marker types for the operand sizes

Structs

• Rsa
  RSA peripheral container
• RsaModularExponentiation
  Support for RSA peripheral’s modular exponentiation feature that could be used to find the (base ^ exponent) mod modulus.
• RsaModularMultiplication
  Support for RSA peripheral’s modular multiplication feature that could be used to find the (operand a * operand b) mod modulus.
• RsaMultiplication
  Support for RSA peripheral’s large number multiplication feature that could be used to find the operand a * operand b.
