This book is my first text book of any sort. Encryptology is meant to be a an easy to pick up guide on getting started with the world of encryption and a quick start guide for many popular encryption applications across multiple platforms.
I would be happy to review any changes or additions you suggest. I understand that I am not the most experienced person with encryption software and will happily accept and pull requests or advice about explaining certain concepts. So feel free to open a pull request or create an issue.
