When I was in elementary school, computers were not as abundant as they are today. It was the moment my father brought home the latest family computer, embedded in it, the Intel 80386 microprocessor, that informed me of the beauty behind what computers were capable of. In those days, when classmates wanted to share notes, we would often exchange a secret note, scrambling the letters so that in the event that the teacher would obtain the note, the message would be illegible to them. The notes were a secure encrypted channel that allowed us to control privacy in our messages.
They were the keys to our world, and there was no way in without them.
