Until now, code that depended on PyCrypto or OpenSSL was defined conditionally (e.g. indented) in `crypt.py`. Rather than grouping all these together, we factor out the library specific behavior into standalone modules (but make the modules private / protected). In addition, added a `_helpers.py` module with common behavior that was previously defined in multiple places. Finally, beefed up some test cases so that the three newly added modules had 100% test coverage. Towards #212.
