40.9. SHA256 algorithm

40.9.1. Overview

sha256_example the example project shows the implementation of sha256 algorithm. - The decryption algorithm of this project adopts NIST sha256 method to complete the module encryption and decryption test.

40.9.2. Board Setting

• No special settings

40.9.3. Running the example

When the project runs correctly, and the serial port terminal will output the following information:

tc_start() - Performing SHA256 tests (NIST tests vectors):

All SHA256 tests succeeded!
===================================================================
PASS - main.
===================================================================
PROJECT EXECUTION SUCCESSFUL

Note

test_14 will take a few minutes to run, please be patient
