Twisted is event programming with Python. Learning events is hard.

Thank God finally someone realized that events are far better than
using threads. I wonder what your problem is though.

All this is irrelevant man. Isn't it a simple download, python setup.py
install affair?

No, twisted has nothing to do with crypto man. It is an event
library for I/O multiplexing. Learn about epoll(2), kqueue() or libevent.

Try to solve this first:

import twisted

;)

Don't mix with crypto. Keep things simple and stupid.

The famous KISS principle.

Best of luck!
