Part A ( 1 ) The Vigenère cipher is a method of encrypting alphabetic text by using a key known as a running key‚ which is generated by a keyword. In a Caesar cipher‚ we have to shift every letter of the alphabet with other number of places The Vigenère cipher consists of many Caesar ciphers in sequence with different shift values. The Caesar cipher with digraph coding provides a means of increasing the key space from 26 to 676 ‚ so the key can take any value between 0 and 675 . ( 2 ) This digraph
