Crypto: RNG
The RNG sample shows how to produce random numbers.
Requirements
The sample supports the following development kits:

When built for the nrf5340dk_nrf5340_cpuapp_ns target, the sample is configured to compile and run as a non-secure application.
Therefore, it automatically includes Trusted Firmware-M that prepares the required peripherals and secure services to be available for the application.
This is also valid for the nrf9160dk_nrf9160_ns build target, if the sample supports it.
Overview
The sample produces random numbers of 100-byte length.
It performs the following operations:
Initialization of the Platform Security Architecture (PSA) API.
Generation of five 100-byte random numbers.
Building and running
This sample can be found under samples/crypto/rng in the nRF Connect SDK folder structure.
See Building and programming an application for information about how to build and program the application.
Testing
After programming the sample to your development kit, complete the following steps to test it:
Connect to the kit with a terminal emulator (for example, PuTTY). See How to connect with PuTTY for the required settings.
Compile and program the application.
Observe the logs from the application using an RTT Viewer or a terminal emulator.
Note
By default, the sample is configured to use both RTT and UART for logging. If you are using RTT, skip the first step of the testing procedure.
