People like to hide things. We all have secrets and the better hidden the secret the safer it is. What if you have secrets that you need to share with others though? Long before computers and their high tech 256 encryption methods, there were ciphers. Seemingly bizarre symbols reconstituted into an almost verbal language. What would you do if you were part of the largest Fraternity with secrets in the world and needed to share info with higher ranks? Why, you would use a cipher of course.
The Freemason’s have long been held as an organization out to rule the world. However if you ask any Mason they will say they don’t have any secrets and you can find any alleged secrets on the internet. This is true but there was a time when they did keep things hidden. Otherwise why would they have a cipher?
