20 I{Paramiko} (a combination of the esperanto words for "paranoid" and "friend")
21 is a module for python 2.3 or greater that implements the SSH2 protocol for
22 secure (encrypted and authenticated) connections to remote machines. Unlike
23 SSL (aka TLS), the SSH2 protocol does not require heirarchical certificates
24 signed by a powerful central authority. You may know SSH2 as the protocol that
25 replaced C{telnet} and C{rsh} for secure access to remote shells, but the
26 protocol also includes the ability to open arbitrary channels to remote
27 services across an encrypted tunnel. (This is how C{sftp} works, for example.)
28
29 The high-level client API starts with creation of an L{SSHClient} object.
30 For more direct control, pass a socket (or socket-like object) to a
31 L{Transport}, and use L{start_server <Transport.start_server>} or
32 L{start_client <Transport.start_client>} to negoatite
33 with the remote host as either a server or client. As a client, you are
34 responsible for authenticating using a password or private key, and checking
35 the server's host key. I{(Key signature and verification is done by paramiko,
36 but you will need to provide private keys and check that the content of a
37 public key matches what you expected to see.)} As a server, you are
38 responsible for deciding which users, passwords, and keys to allow, and what
39 kind of channels to allow.
40
41 Once you have finished, either side may request flow-controlled L{Channel}s to
42 the other side, which are python objects that act like sockets, but send and
43 receive data over the encrypted session.
