Morse Code

Morse code is a system of communication that uses two different signal durations, called dots and dashes, to encode text characters. It was invented by Samuel F.B. Morse in the 1830s and became widely used for telegraphy, the transmission of messages over long distances by electric wires. Morse code can also be transmitted by other means, such as light, sound or radio waves. Morse code is still used today by amateur radio operators, pilots, sailors and some military forces.

"SOS" is an international distress signal, these three letters are not the abbreviation of any word, just because its code "...---..." (three dots, three long, three dots) is the easiest to send out and identify in telegrams code.

Simple Substitution Cipher is a cipher that has been in use for many hundreds of years. It basically consists of substituting every plaintext character for a different ciphertext character.

Straddle Checkerboard Cipher is a substitution cipher, except that the substitutions are of variable length. It has formed a component of several impotant field ciphers, the most notable being the VIC cipher used by russian spies during the cold war.
