5 Points 3 Georgian Alphabet 33 Letters Represent Integer Values 0 32 Going Encrypt Georgi Q43855893
(5 points) 3. The Georgian alphabet has 33 letters and we canrepresent them with the integer values 0 to 32. If we are going toencrypt a Georgian plaintext using the affine cipher, how manypossible keys are there, that is, what is the size of the keyspace?
(5 points) 4. If an alphabet has 31 letters, what is the size ofthe key space using the affine cipher?
(5 points) 5. Solve Computer Problem 1 on p. 59. I recommendwriting a program but that’s not necessary.
(10 points) 6. Solve Computer Problem 6 on p. 60. You may writea program for part (a) but you must write a program for part (b).The program may be in the “usual” languages, that is, C++, Java, orPython. Other languages may be used with permission.
The next two problems are based on this Vigenèreciphertext.

(10 points) 7. Write a program based on the followingpseudocode to determine the likely length of the key used to createthe above ciphertext. This is the technique described in section2.3.1.
for shift = 1 to 14 do coincidenceCount = 0 for index = 0 to ciphertext length – 1 do shiftedIndex = (index + shift) % ciphertext length if ciphertext[index] == ciphertext[shiftedIndex] then coincidenceCount++; print shift, coincidenceCount
(5 points) 8. Please break the above ciphertext using anonline resource to help. There are some sites that, given theciphertext, determine the key word and provide the plaintext.Format the plaintext by adding word spaces andpunctuation.
