  # remember it was a single English word. Trying to guess your forgotten password
  # is quite a boring task. Instead you can write a program that will decrypt the
  # PDF by trying every possible English word until it finds one that works.
  #
  # Create a list of word strings by reading dictionary.txt. Then loop over each word in
  # this list, passing it to the decrypt() method. If this method returns the integer
  # 0, the password was wrong and your program should continue to the next password.
  # If decrypt() returns 1, then your program should break out of the loop and print
  # the hacked password. You should try both the uppercase and lower-case form of
  # each word.
