- Null_cipher abstract "A null cipher is an ancient form of encryption where the plaintext is mixed with a large amount of non-cipher material. It would today be regarded as a simple form of steganography. Null ciphers can also be used to hide ciphertext, as part of a more complex system.In classical cryptography a null is intended to confuse the cryptanalyst. Typically, a null will be a character which decrypts to obvious nonsense at the end of an otherwise intelligible phrase. In a null cipher, most of the characters may be nulls.An example follows (Kipper 9):News Eight Weather: Tonight increasing snow. Unexpected precipitation smothers eastern towns. Be extremely cautious and use snowtires especially heading east. The [highway is not] knowingly slippery. Highway evacuation is suspected. Police report emergency situations in downtown ending near Tuesday.Taking the first letter in each word successively yields the real message: "Newt is upset because he thinks he is President."You can also choose to instead use the last letter of every word, or something like a pattern such as:Susan sAys GaIl Lies. MAtt leTs Susan fEel joVial. Elated (or) aNgry? Using the pattern ( 1,2,3,1,2,3 [each letter in each word] ) gives the message: "Sail at seven."".
