At the bright age of fourteen I was luentfay taay igPay atinLay (fluent at Pig Latin). It was a lot of fun and trivial practicing it with class mates at that. Sometimes it was probably better that we spoke in Pig Latin so that the teacher couldn't understand it. Unless, of course, the teacher knew how to speak it as well.
I'm not real sure how Pig Latin originated but it's a basic idea. The encipher mechanism is to take the first letter of the first word (P from Pig), place it as the last letter of the word (igP), then add ay to finish the word (igPay). Once you understand the cipher you can encipher or cipher, code or decode, intelligible words to un-intelligible words for those that don't have the cipher. This is the basic idea of encryption.
Encryption is a way to translate electronic information to un-intelligible data, except for those who have the cipher (key in encryption jargon). With this key you can keep the information locked from those who shouldn't have access to it, and conversely unlocked to those who need access to it.
There aren't a lot of sensitive things I needed to encrypt as a child. But as a professional, any kinds of company data could become malicious in the wrong hands. Thus keeping it safe by encryption is significantly important. Quality grade school teachers are no longer preoccupied about your business. Professionally, there are bigger things at stake and access to information becomes less trivial.
