Share3 Shares 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.
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. For example, a message might be written on paper, coated with wax, and swallowed to conceal it, only to be regurgitated later.
Another way is to tattoo the message on the shaved head of a messenger and wait for the hair to regrow to cover up the ink.
The best stenography uses innocent everyday objects to carry messages. A once-popular technique in England was to use a newspaper with tiny dots under letters on the front page indicating which ones should be read to spell out the message. Some people would spell out a message using the first letter of every word, or use invisible ink.
Rival countries have shrunk writing down so that an entire page of text becomes the size of a pixel which is easily missed by prying eyes. Steganography is best used in conjunction with a code or cipher, as a hidden message always carries the risk of being found.
Its key is simple: This cipher is fun because it is easy to understand and use, but it is equally easy to decipher if they key is used in reverse.
This cipher is not suitable for serious use but can be of great amusement for children. Complex rules of rearrangement can make these ciphers seem very difficult at first, but many transposed messages can be deciphered using anagrams or modern computer algorithms which test thousands of possible transposition keys.
To test yourself, try to decipher: Unlike most other ciphers, it is not used to conceal messages. It involved laying a long wire between places and running an electric current down the wire. The electric current could be detected by a receiver many kilometers away, and dots and dashes were simulated by turning the current on and off.
The telegraph revolutionized media, allowing events in one country to be immediately reported in another, and it changed the nature of warfare by allowing instantaneous communication with troops a long distance away.
ROT1 is just one of these ciphers. A person only needs to be told which Caesar cipher was used in order to decipher a message. This cipher is the basis for many more complex ciphers, but on its own does not allow great protection of a secret message, as checking 26 different cipher keys does not take a relatively great amount of time.

Writing: Writing, form of human communication by means of a set of visible marks that are related, by convention, to some particular structural level of language. This definition highlights the fact that writing is in principle the representation of language rather than a direct representation of thought. The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BC. It was derived from the earlier Phoenician alphabet, and was the first alphabetic script to have distinct letters for vowels as well as consonants.
