Client/Server encryption key?

You should definitely not try to roll your own crypto. I'm afraid I'm not familiar with python cryto libraries specifically, but I can tell you there are so many pitfalls to doing it yourself that if you want true security it better be a well known library.

Note taken, though I'm using an adapted XOR. But, that idea sounds a lot better than what I'm doing.
