The need to conceal the meaning of important messages has existed for thousands of years. Over time, people have found increasingly complex ways of encoding their messages as the simpler ways are decoded with greater ease. Contrary to layman-speak, codes and ciphers are not synonymous. A code is where each word in a message is replaced with a code word or symbol, whereas a cipher is where each letter in a message is replaced with a cipher letter or symbol. In fact, when most people say "code," they are actually referring to ciphers. Ancient scripts and languages have been understood using decoding and deciphering techniques, most famously the Rosetta Stone of Ancient Egypt. In fact, codes and ciphers have determined the outcome of politics and wars throughout history. There are thousands of types of hidden messages, but here we look at only ten as an overview. Several have examples for you to test yourself with. @seulyoon_park
