Tests pass against Python 2.7 and 3.4 so far. All changes were applied manually (that is, without any conversion tools), so I believe the meaning and intent of all functions have been preserved. Signed-off-by: Yung-Chin Oei <yungchin@yungchin.nl>

Ugh, wait a second. I was trying to avoid messing around with types with this change, but this change doesn't ensure the returned str is of length 32.
The parent commit tried a silly substition for `hexify`, seeking to work around the problem that `chr` has a different return type in py3. This brings back `hexify` to ensure that the output of `redactable_rand` is always as expected: a hexadecimal `str` of length 64. Signed-off-by: Yung-Chin Oei <yungchin@yungchin.nl>
This fix is only necessary to run the tests on a platform that does not default to utf-8. To remain py2.7 compatible, we needed to replace `open()` as the built-in does not let you specify an encoding. Signed-off-by: Yung-Chin Oei <yungchin@yungchin.nl>

This set of changes to the Python implementation is sufficient for tests to pass both on 3.4 and 2.7 - if support for older versions is desirable, a bit more work would need doing.
I've aimed to keep changes as minimal as possible, and functional behaviour unchanged.
