  # Filename:  prependEmoji.py 
  #
  # Version: 1.0.0
  #
  # Author:  Joe Gervais (TryCatchHCF)
  #
  # Summary: Inserts a random emoji in front of each line in a file. Used to 
  # add noise to a cloaked file (see cloakify.py) in order to degrade frequency 
  # analysis attacks against the cloaked payload. Works well with the emoji 
  # cipher.
  # 
  #
  # Description:  
  # 
  # Example:  
  #
  #   $ ./prependEmoji.py exfiltrate.txt > exfiltrateNew.txt
  # 
  #   Remove prepended emoji before trying to decloak the file
  # Updated to Python3 by John Aho
