it is better to create than to learn
The bust of Caesar was a giveaway that this was the Caesar cypher which is just a simple letter shift. From there it was trivial to guess starting with the two letter words. Guess one letter and shift the others by the same amount and see if it makes sense. Once 'i' is tried for the first letter, shifting all letters by the same amount (back 3) reveals the message.
I don't know when I first hear of the Caesar cypher. Probably in Latin class or reading Cryptonomicon by Neal Stephenson...
Very good! That is correct! The Caesar Cipher is one of the simplest and oldest cryptography methods! The next challenge wont be as easy, I hope you follow and will give future challenges a try! I will transfer your prize of 5 STEEM!
