Compatibility ************* Python Versions Supported ========================= ssh-deploy-key is currently only compatible with cpython 2.7. Unsupportable Python Versions ============================= SSH Deploy Key uses the Paramiko ssh library. Paramiko is not a "pure python" solution. It has binary dependencies that make it incompatible with non-cpython implementations, including: * jython * pypy Python 3 ======== Getting Python 3 support in ssh-deploy-key is a priority. Unfortunately, the ssh library we use -- Paramiko -- does not yet support Python 3. When this is available, we'll update ssh-deploy-key right away to include Python 3 support. See this thread for more info on the status of running Paramiko on Python 3: https://github.com/paramiko/paramiko/issues/16
