Title: Improve the Encryption library

Changes include:

- Method & property visibility declarations
- Minor speed optimizations
- Cleaned up & some comments and unnecessary code

NOTE:

I intend to do this for each of the libraries (and probably other stuff as well) separately as none of my similar pull requests that have changes to multiple classes have been accepted - I hope those make it.
With that in mind - I'll just add one line under general changes in the change log when it's all done, to avoid multiple entries with the same description and only the class name changed.
