a) Given plaintext "LOVE" , if we know the encryption algorithem is Affine Cipher and we know the key (a,b) = (7,9), please generate the ciphertext.

b) Based on the Affine Cipher in a) if you receive a ciphertext 'VDT" please decrypt it to the original.

c) Given plaintext "LOVE" , if we know the enceyption algorithem is Vignere ciphere and we know the key (7,9) please generate the cipheretext.

d) Based on vigenere ciphere in c) if you receive a ciphertext "ABCD" PLEASE DECRYPT IT TO THE ORIGINAL PLAINTEXT.
