The RNG mrbgem implements generation of random numbers and strings. The main purpose of this is to generate random keys for cryptographic operations.
The API of the gem looks like the following:
RNG.random_int: generates a 32-bit random integer.%operator to get the residual.RNG.random_string(length): generates a string of lengthlengthwith random bytes.This gem currently has an implementation for RP2040 that uses RP2040's Ring Oscillator (-> https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.pdf, Section 2.17).
