[ Example ] Hash

This example demonstrates hash computation using the STSAFE-A120 secure element.

Example Overview

The Hash example application illustrates how to compute a SHA-256 hash message using platform crypto library and using STSAFE-A120 device.

Example Flowchart

The following flowchart outlines the main steps performed by the hash computation example application:

Host Terminal Output

Upon execution, the host terminal displays logs reflecting the ECDH key agreement process, including key generation, public key exchange, and the resulting shared secret.

Example output:
