Question: Consider the file hexsubcipher.txt. The text is encrypted the text of a famous book to generate this ciphertext. He used a substitution cipher, but applied

Consider the file hexsubcipher.txt. The text is encrypted the text of a famous book to generate this ciphertext. He used a substitution cipher, but applied it to the hexdump of the original file, randomly replacing each hex character with a different hex character. One way to do this would be $ cat original | xxd -p | tr '0-9a-f' '1a0fed543bc28679' > encrypted The ciphertext on this problem was generated with a command like this, but with a different key. Your job is again to determine which famous book the original message comes from. You should submit the name of the book, as well as a detailed explanation of how you solved the problem, including any commands you used. Hint: one thing that is different in this problem is that non-letter characters will now be encrypted as well. For example, using the key in the command above, a newline character (0a in hex) would be translated to 1c.
