Some labs may wish to better protect their data from casual inspection or accidental disclosure. This is possible within PsychoPy using a separate python package, pyFileSec, which grew out of PsychoPy. pyFileSec is distributed with the StandAlone versions of PsychoPy, or can be installed using pip or easy_install via https://pypi.python.org/pypi/PyFileSec/
Some elaboration of pyFileSec usage and security strategy can be found here: http://pythonhosted.org/PyFileSec
Basic usage is illustrated in the Coder demo > misc > encrypt_data.py
