I think I understand a good amount of the theory behind elliptic curve cryptography, however, I am slightly unclear on how exactly a message is encrypted and then how is it decrypted. I am using the ATECC608A module with i2c interfacing. So my questions are
If there is any example code for it, it would be of great help if you share it.
I need to know step by step instructions to program it.
Thanks for the help
That's a Microchip product: https://www.microchip.com/wwwproducts/en/ATECC608A - it has nothing to do with Keil or ARM (or even ST).

You need to study the Microchip documentation for answers to those questions!
If you then have further questions, you need to ask Microchip:

Again, you need to ask Microchip for that.
Look on the 'Development Environment' tab of the Product Page - linked above.

Take a look at the 'Security' section of their YouTube channel:

Look to Microchip and/or your local distributor for support/training/seminars etc...
