secure ftp python module for ConnectCore 3G 9P

I am writing some python code for our digi module and I need to send files via secure ftp. I noticed that in Python 2.7 the ftp lib has some support for this but not Python 2.4. I also looked into Paramiko but it doesn’t appear to be pure python (or one of it’s dependencies isn’t) Does anyone know of a python module that I can use for this?
