Fix issue "Folder content is not encrypted #36" and Fixed Critical Security Bug

Critical Security Bug

So first lets start with the Critical Security Bug. So the bug is that when you delete files you used

fs::remove_file("some file")

This data can be recovered, so I make a new functions delete_file and delete_folder. These functions write random bytes in the place of the file, thus making impossible to recover the file, thus solving the security bug. While this function is slower it is very good to use, especially with encryption in play.

Fix issue "Folder content is not encrypted #36"

The title is quite self explanatory but issue 36 is done and it works well!

Other Notes

While working on your projects I had some critiques, I recommend you type out your variable names instead of using abbreviations, it makes your code quite confusing to read.

Other that this I love your project and I hope it sees a bigger field! I wish you the best of luck!
