Remote Agent Keyring

Implements a remote agent keyring for use over SSH connections.

Requires OpenSSH 6.7.

To use, on the host machine, install jaraco.keyring and invoke the server:

python -m jaraco.keyring.server

That starts a server listening only on localhost:4273.

Then, connect to the remote host and forward the traffic back to the keyring server:

ssh -R /tmp/keyring.sock:localhost:4273 remote_host

This command creates a unix domain socket at /tmp/keyring.sock which only that user can access.

Then, on that host, configure keyring to use the remote agent backend. For example,

keyring -b jaraco.keyring.RemoteAgent get SERVICE USERNAME

The remote agent backend will request the password over the tunnel, where the server will request the password using the default configuration.
