I have attached a sample project. I end up with these sorts of errors, I am unclear how to resolve.

Hi Chad, 
Could you let me know what you want to achieve here? 
Have you went through the Academy course ? 

My assumption is that you want to add image encryption into DFU solution ? 
If you look at this ticket you can find that encrypted image is not supported out of the box. 

However one of our coworkers made an example here that you may want to take a look.
Please be aware that the example provided "as-is" and you should have a good understanding of how MCUBoot work to use it.
