To crack the Vigenère cipher, you can use techniques such as frequency analysis, the Kasiski examination, or the Friedman test. Start by identifying repeated segments of ciphertext to estimate the key length. Then, separate the ciphertext into groups based on the key length and analyze the frequency of letters within each group to determine the likely characters of the key. Once the key is identified, you can decrypt the ciphertext to reveal the original message.

Using a keyword as long as the message will make a vigenere cipher unbreakable.

What do you do to get the key word to a vigenere cipher when you want to solve the cipher?

It depends on the cipher used. Some can be attacked and broken in minutes; others are unbreakable in practise; and some can never be broken.

Difference of polyalphabetic substitution cipher and polyalphabetic cipher?

In a monoalphabetic cipher, our substitution characters are arandom permutation of the 26 letters of the alphabet:plaintext letters: a b c d e f .....substitution letters: t h i j a b .....• The key now is the sequence of substitution letters. In otherwords, the key in this case is the actual random permutation ofthe alphabet used.For a particular alphabet, only one substitution can be usedexample: if the substitution letter for 'a' is 't' and for 'd' it is 'p'then if the keyword happens to be "tpp"..... then we can encrypt the message as "add"(note that the substitution letter for 'd' is only 'p'..In a monoalphabetic cipher, the same substitution rule is used forevery substitution. In a polyalphabetic cipher, the substitutionrule changes continuously from letter to letter according to theelements of the encryption key.Example for polyalphabetic:key: abracadabraabracadabraabracadabraabplaintext: canyoumeetmeatmidnightihavethegoodsciphertext: CBEYQUPEFKMEBK.....................• The Vigenere cipher is an example of a polyalphabetic cipher.

What was the impact of the enigma machine?

Turing did not work on the Enigma, it was a German machine. However he did do some work on the British Bombe machines that were used to crack the Enigma machine cipher. Later he saw Tommy Flowers' Colossus electronic computer, designed to crack the German Lorenz SZ40/42 machine cipher. This inspired him after the end of the war to begin work on programmable electronic computers.
