PyPI listed this little gem this evening: paramiko. What is paramiko? It is an SSH2 implementation in Python. Here’s some more information from PyPI:
This is a library for making SSH2 connections (client or server). Emphasis is on using SSH2 as an alternative to SSL for making secure connections between python scripts. All major ciphers and hash methods are supported.
SFTP client mode is now supported too.
paramiko relies on PyCrypt, which is like a Pythonic Bouncy Castle.
