write an encoder and a decoder for a modified "book cipher." A book cipher uses a document or book as the cipher key, and the cipher itself uses numbers that reference the words within the text. For example, one of the Beale ciphers used an edition of The Declaration of Independence as the cipher key. The cipher you will write will use a pair of numbers corresponding to each letter in the text. The first number denotes the position of a word in the key text (starting at 0), and the second number denotes the position of the letter in the word (also starting at 0). For instance, given the following key text (the numbers correspond to the index of the first word in the line) [0] 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe; [13] All mimsy were the borogoves, And the mome raths outgrabe.

Could you devise a key that when it is used on the ciphertext you produced in 1.a, will provide plaintext relish instead of the strike? the photo below is question 1a and please trying to be as detailed as possible when answering the question, justifying well all your steps that you did.
q5- The Atbash cipher is a type of monoalphabetic cipher formed by taking the alphabet and mapping it to its reverse, so that the first letter becomes the last letter, the second letter becomes the second to last letter, and so on. For example: A becomes Z and Z becomes A, B becomes Y and Y becomes B, and so on. Numeric digits and special symbols will remain the same. What does XHV2HRZ mean?
Can you please show the shifts for the encrypt & decrypt in this format? For example, like this : Example:ABCDEFGHIJKLMNOPQRSTUVWXYZ Row 1FGHIJKLMNOPQRSTUVWXYZABCDE Row 2 If the plaintext to encrypt is:THIS IS THE ANSWER The ciphertext becomes:YMNX NX YMJ FSXBJW This is for me to help understand and to redo the problem for studying. Thank you!!
