Have fun learning about and using some of the most important ciphers and codes used throughout history and satisfy your inner nerd in the process! Have you ever been intrigued by secret codes and ciphers? Have you ever wondered how messages were encrypted before computers existed? Have you been fascinated by the story of the Enigma machine and wanted to know how it worked? Inspired by a visit to Bletchley Park in England, home of the UK codebreakers during the 1939-1945 world war, CipherBoB lets you explore some of the most important codes and cipherers used throughout history. Using CipherBob you can create ciphers of each type and then use these to encipher messages to send to your friends or decipher messages received from your friends and in the process learn about the cipherers you use. The app includes a brief summary of the history of each cipher type as well as step by step walk through of how each cipherer worked. Ciphers currently supported by * Caesar ciphers - the cipher that Julius Caesar used for all his secret communications * Substitution ciphers - the natural successor of the Caesar cipherer and still used today * Polybius Square ciphers - perhaps the first fractionating cipherer * Book ciphers - perhaps the favourite cipherer of mystery writers and movies * Morse code - want to try your hand at tapping out some Morse or perhaps you have some Morse audio you want to capture and decode * The infamous Enigma machine - you can use our Enigma engine to encrypt/decrypt messages between you and your friends or configure the engine to decode the messages used in the many books and movies on the subject * Public/Private key ciphers - the cornerstone of a secure internet, learn how they work from a very simple implementation Today’s New Idea is a “not for profit” business so all proceeds from the sale of this app go toward the development of other apps we hope users will find educational or beneficial.
