While trying to decode and then extract the text from the above/attached file, I encountered this error:

  File "mypython.py", line 149, in <module>
    pdf.decrypt('')
  File "/home/mibearin/lsr/projects/fcc/python/pyPdf/pdf.py", line 894, in decrypt
    return self._decrypt(password)
  File "/home/mibearin/lsr/projects/fcc/python/pyPdf/pdf.py", line 904, in _decrypt
    user_password, key = self._authenticateUserPassword(password)
  File "/home/mibearin/lsr/projects/fcc/python/pyPdf/pdf.py", line 959, in _authenticateUserPassword
    encrypt["/Length"].getObject() / 8, owner_entry,
TypeError: 'NullObject' object is unsubscriptable

Although the file is not encrypted (or may be encrypted with a blank key), if I do not attempt to decrpyt the file, I receive the following error:

Exception: file has not been decrypted
