Benchmark demonstration program for mbed TLS. The canonical source for this example lives at https://github.com/ARMmbed/mbed-os-example-tls

Mbed TLS Benchmark example on Mbed OS

This application benchmarks the various cryptographic primitives offered by Mbed TLS.

Getting started

Building with Mbed CLI

If you'd like to use Mbed CLI to build this, then you should set up your environment if you have not done so already. For instructions, refer to the main readme. The instructions on this page relate to using the developer.mbed.org Online Compiler

Import the program in to the Online Compiler, select your board from the drop down in the top right hand corner and then compile the application. Once it has built, you can drag and drop the binary onto your device.

Monitoring the application

The output in the terminal window should be similar to this:
