Unit 5 Lesson 7 Exemplar for the final part of the activity guide

I am working with someone who would like an exemplar for the final part of the activity guide. U5L07 - Exemplar - Keeping Data Secret - Google Docs.
There are exemplars for every part of the activity guide except for the part “Encrypt Your Own Message” and “Decrypt a Classmate’s Message”.
Does anyone have an example to share?

I went back and looked through the lesson and didn’t see the exemplar for that part either. Odd! It’s very similar to the medical records section of the other handout. Maybe you could use that as an example of how it’s done? Maybe someone else has some student work samples they could share.

Thanks I was hoping someone would share.
