Hello world example of using the authenticated encryption with 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 performs authenticated encryption and authenticated decryption of a buffer. It serves as a tutorial for the basic authenticated encryption functions of 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:
