Handling Password Authentication over a Network

问题

I'm writing a game which requires users to log in to their accounts in order to be able to play. What's the best way of transmitting passwords from client to server and storing them?

I'm using Python and Twisted, if that's of any relevance.

回答1:

The best way is to authenticate via SSL/TLS. The best way of storing passwords is to store them hashed with some complex hash like sha1(sha1(password)+salt) with salt.

回答2:

If you want plug'n'play solution, use py-bcrypt for storing passwords (http://www.mindrot.org/projects/py-bcrypt/) and SSL/TLS to protect them in transit.
