Crypto: Spake2+

The Spake2+ sample demonstrates how to do a password-authenticated key exchange using the Spake2+ protocol.

Requirements

The sample supports the following development kits:

Hardware platforms	PCA	Board name	Build target
nRF9161 DK	PCA10153	nrf9161dk_nrf9161	nrf9161dk_nrf9161_ns nrf9161dk_nrf9161
nRF9160 DK	PCA10090	nrf9160dk_nrf9160	nrf9160dk_nrf9160_ns nrf9160dk_nrf9160
nRF54L15 PDK	PCA10156	nrf54l15pdk_nrf54l15	nrf54l15pdk_nrf54l15_cpuapp_ns nrf54l15pdk_nrf54l15_cpuapp
nRF54H20 DK	PCA10175	nrf54h20dk_nrf54h20_cpuapp	nrf54h20dk_nrf54h20_cpuapp
nRF5340 DK	PCA10095	nrf5340dk_nrf5340	nrf5340dk_nrf5340_cpuapp_ns nrf5340dk_nrf5340_cpuapp
nRF52840 DK	PCA10056	nrf52840dk_nrf52840	nrf52840dk_nrf52840

Overview

The sample performs the following operations:

1. Initializes the Platform Security Architecture (PSA) API.

2. Goes through the steps for Spake2+ on server and client sides.

3. Verifies that the derived keys are the same.

Building and running

Testing

After programming the sample to your development kit, complete the following steps to test it:

1. Connect to the kit with a terminal emulator (for example, nRF Connect Serial Terminal). See Testing and optimization for the required settings and steps.

2. Compile and program the application.

3. Observe the logs from the application using a terminal emulator.
