Primary differences between SSH and HTTPS. This post is specifically about accessing Git repositories on GitHub.

Protocols to choose from when cloning:

plain Git, aka git://github.com/

• Does not add security beyond what Git itself provides. The server is not verified.

  If you clone a repository over git://, you should check if the latest commit's hash is correct.
