Internal Program Version: paramiko  3.1.0

paramiko is a module for python 2.2 (or higher) that implements
the SSH2 protocol for secure (encrypted and authenticated)
connections to remote machines. unlike SSL (aka TLS), SSH2
protocol does not require heirarchical certificates signed
by a powerful central authority. you may know SSH2 as the
protocol that replaced telnet and rsh for secure access to
remote shells, but the protocol also includes the ability
to open arbitrary channels to remote services across the
encrypted tunnel -- this is how sftp works, for example.
