[PYTHON-CRYPTO] key storage for encryption on Windows (Python and pyCrypto)

[Gagnesh Kumar]

If we are encrypting a file/data, then we have to keep the key, because
we'll need it later for decryping the file/data.
Assuming that the key is written down in the file system, what would be the
best way to keep it secure and private to legitimate users on Windows?
We want to do this using Python2.4 and pyCrypto.
Cheers,
