• Overview
• Building and running
  • Testing

The ECDH sample shows how to perform an Elliptic-curve Diffie–Hellman key exchange to allow two parties to obtain a shared secret.

Requirements

The sample supports the following development kits:

.. table-from-sample-yaml::

Overview

The sample performs the following operations:

1. Initialization:
   1. The Platform Security Architecture (PSA) API is initialized.
   2. Two random Elliptic Curve Cryptography (ECC) key pairs are generated and imported into the PSA crypto keystore.
2. ECDH key exchange using the generated key pairs.
3. Cleanup:
   1. The key pairs are removed from the PSA crypto keystore.

Building and running

Testing

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

1. |connect_terminal|
2. Compile and program the application.
3. Observe the logs from the application using a terminal emulator.
