NOTE: The Version 1.2 will not be able to decrypt & read a files uploaded from Version 1.3!
If you share Box with someone else, then both of you should have the same Protocol ver.

P.S.

Sorry for delay with this update. Got some procrastination alongside with abnormal heat in my region.
Redstone in Minecraft played its role too xD
