 * \section Main
 *  CryptImpHook is a CPython Import Hook (see PEP-302) that allows encrypted Python modules
 *  to be used in a transparent manner in any Python application. The encrypted
 *  modules have a .pye extension.
 *
 *  This code is just a proof-of-concept and implements the XOR encryption
 *  with a given key. If you would like to change the encryption cipher or mechanism, you could
 *  implement yours by re_writing the cih_read_module_code function.
 *
 *  This is public domain code.

To build & test, just run: make && make test For docs, run: make docs

This requires Python =< 2.7 to run.

You will find the key in src/CryptImpHook.h. To encrypt your Python modules, use dist/CryptConv <source_file> <dest_file> Encrypted Python modules will have a .pye extension.

Disclaimer:

XOR cipher is not a strong encryption algorithm. You should not use this code in Production systems. This is just a proof-of-concept, to be completely useful, you should implement the encryption/decryption with some proven algorithm or cipher, like AES or 3DES, use a large char[] for your key, and add -O2 to the code so it gets harder for anybody to dissect the key.
