History of encryption:
Encryption is said to be as long as civilization. In fact, writing has been considered to be one of the first forms of encryption, as only the rich and educated civilians could read and understand the text. Moreover, looking at more recent times, the Navajo windtalkers was a language used by the American military in the second world war to communicate. This particular language was used as it so intricate that only American natives could make any sense out of it hence disadvantaging the enemy [B2].
However, “the first documented use of cryptography” [2] was in Egypt 1900 BC. The Egyptians used a non-standard set of hieroglyphs to hide the meaning of a message [A]. After that in 500-600 BC Hebrew, a reverse alphabet substitution called ABASH was used to encrypt messages [A]. The reverse substitution cipher worked by using “the last letter of the alphabet was used as the first, and vice versa” [B]. The only way to break this cipher was to use the same technique that was used to encrypt it but in reverse.
Then around 486 BC, the Skytale message was used to sent military messages from one place to another. This technique worked by writing a message down on a strip of papyrus or leather around a stick of a particular radius. Once the strip is removed from the strip, the message becomes unreadable. So the receiver usually had a similar stick, with the same radius, and all they had to do was to wrap the strip around the stick. This method could be broken by using different sized sticks until the message aligned up to seem sensible [B].

...ree to create a backdoor, they would need to spend a lot of money in the creation of that complex feature plus there will be no guarantee that their customers would want to use their services as it would now contain a loop hole. Moreover, once a backdoor is made, there is no way to control who may able to access the data, hence it is predicted that there will be an increase in cyber criminals who would also want to access sensitive data for personal benefits [K].
Another consequence of encryption will be the “ability of governments to tax” [C]. This is because professionals would be able to sell their services over encrypted data which would hence restrict the government from knowing when services are being exchanged. This may be another key reason as to why the government would oppose such technology and instead restrict or demand for back doors to be developed [C].
