Simple object containing the security preferences of an ssh transport.
These are tuples of acceptable ciphers, digests, key types, and key
exchange algorithms, listed in order of preference.
Changing the contents and/or order of these fields affects the underlying
L{Transport} (but only if you change them before starting the session).
If you try to add an algorithm that paramiko doesn't recognize,
C{ValueError} will be raised. If you try to assign something besides a
tuple to one of the fields, C{TypeError} will be raised.

An SSH Transport attaches to a stream (usually a socket), negotiates an
encrypted session, authenticates, and then creates stream tunnels, called
L{Channel}s, across the session. Multiple channels can be multiplexed
across a single session (and often are, in the case of port forwardings).

Create a new SSH session over an existing socket, or socket-like
object. This only creates the Transport object; it doesn't begin the
SSH session yet. Use L{connect} or L{start_client} to begin a client
session, or L{start_server} to begin a server session.
If the object is not actually a socket, it must have the following
methods:
- C{send(str)}: Writes from 1 to C{len(str)} bytes, and
returns an int representing the number of bytes written. Returns
0 or raises C{EOFError} if the stream has been closed.
- C{recv(int)}: Reads from 1 to C{int} bytes and returns them as a
string. Returns 0 or raises C{EOFError} if the stream has been
closed.
- C{close()}: Closes the socket.
- C{settimeout(n)}: Sets a (float) timeout on I/O operations.
For ease of use, you may also pass in an address (as a tuple) or a host
string as the C{sock} argument. (A host string is a hostname with an
optional port (separated by C{":"}) which will be converted into a
tuple of C{(hostname, port)}.) A socket will be connected to this
address and used for communication. Exceptions from the C{socket} call
may be thrown in this case.
@param sock: a socket or socket-like object to create the session over.

Terminate this Transport without closing the session. On posix

Negotiate a new SSH2 session as a client. This is the first step after
creating a new L{Transport}. A separate thread is created for protocol
negotiation.
If an event is passed in, this method returns immediately. When
negotiation is done (successful or not), the given C{Event} will
be triggered. On failure, L{is_active} will return C{False}.
(Since 1.4) If C{event} is C{None}, this method will not return until
negotation is done. On success, the method returns normally.
Otherwise an SSHException is raised.
After a successful negotiation, you will usually want to authenticate,
calling L{auth_password } or
L{auth_publickey }.
@note: L{connect} is a simpler method for connecting as a client.
@note: After calling this method (or L{start_server} or L{connect}),
you should no longer directly read from or write to the original

Negotiate a new SSH2 session as a server. This is the first step after

If an event is passed in, this method returns immediately. When
negotiation is done (successful or not), the given C{Event} will
be triggered. On failure, L{is_active} will return C{False}.
(Since 1.4) If C{event} is C{None}, this method will not return until
negotation is done. On success, the method returns normally.
Otherwise an SSHException is raised.
After a successful negotiation, the client will need to authenticate.
Override the methods

After a successful authentication, the client should request to open

Return the active host key, in server mode. After negotiating with the

type of host key was set with L{add_server_key}, that's the only key
that will ever be returned. But in cases where you have set more than
one type of host key (for example, an RSA key and a DSS key), the key
type will be negotiated by the client, and this method will return the
key of the type agreed on. If the host key has not been negotiated
yet, C{None} is returned. In client mode, the behavior is undefined.

Load a file of prime moduli for use in doing group-exchange key
negotiation in server mode. It's a rather obscure option and can be
safely ignored.
In server mode, the remote client may request "group-exchange" key
negotiation, which asks the server to send a random prime number that
fits certain criteria. These primes are pretty difficult to compute,
so they can't be generated on demand. But many systems contain a file
of suitable primes (usually named something like C{/etc/ssh/moduli}).
If you call C{load_server_moduli} and it returns C{True}, then this
file of primes has been loaded and we will support "group-exchange" in
server mode. Otherwise server mode will just claim that it doesn't
support that method of key negotiation.

know that it's not in a standard location.

If a handler is given, that handler is called from a different thread
whenever a forwarded connection arrives. The handler parameters are::

where C{server_addr} and C{server_port} are the address and port that
the server was listening on.

to add "noise" to a connection to confuse would-be attackers. It can
also be used as a keep-alive for long lived connections traversing
firewalls.

Force this session to switch to new keys. Normally this is done
automatically after the session hits a certain number of packets or
bytes sent or received, but this method gives you the option of forcing
new keys whenever you want. Negotiating new keys causes a pause in
traffic both ways as the two sides swap keys and do computations. This
method returns when the session has switched to new keys.

Turn on/off keepalive packets (default is off). If this is set, after

Negotiate an SSH2 session, and optionally verify the server's host key
and authenticate using a password or private key. This is a shortcut
for L{start_client}, L{get_remote_server_key}, and
L{Transport.auth_password} or L{Transport.auth_publickey}. Use those
methods if you want more control.
You can use this method immediately after creating a Transport to
negotiate encryption with a server. If it fails, an exception will be
thrown. On success, the method will return cleanly, and an encrypted
session exists. You may immediately call L{open_channel} or
L{open_session} to get a L{Channel} object, which is used for data
transfer.
@note: If you fail to supply a password or private key, this method may
succeed, but a subsequent L{open_channel} or L{open_session} call may
fail because you haven't authenticated yet.
@param hostkey: the host key expected from the server, or C{None} if
you don't want to do host key verification.
@type hostkey: L{PKey}
@param username: the username to authenticate as.
@type username: str

@type password: str
@param pkey: a private key to use for authentication, if you want to

@raise SSHException: if the SSH2 negotiation fails, the host key
supplied by the server is incorrect, or authentication fails.

Authenticate to the server using a private key. The key is used to
sign data from the server, so it must include the private part.
If an C{event} is passed in, this method will return immediately, and
the event will be triggered once authentication succeeds or fails. On
success, L{is_authenticated} will return C{True}. On failure, you may
use L{get_exception} to get more detailed error information.
Since 1.1, if no event is passed, this method will block until the
authentication succeeds or fails. On failure, an exception is raised.
Otherwise, the method simply returns.
If the server requires multi-step authentication (which is very rare),
this method will return a list of auth types permissible for the next
step. Otherwise, in the normal case, an empty list is returned.

Authenticate to the server interactively. A handler is used to answer
arbitrary questions from the server. On many servers, this is just a
dumb wrapper around PAM.
This method will block until the authentication succeeds or fails,
peroidically calling the handler asynchronously to get answers to
authentication questions. The handler may be called more than once
if the server continues to ask questions.
The handler is expected to be a callable that will handle calls of the
form: C{handler(title, instructions, prompt_list)}. The C{title} is
meant to be a dialog-window title, and the C{instructions} are user
instructions (both are strings). C{prompt_list} will be a list of
prompts, each prompt being a tuple of C{(str, bool)}. The string is
the prompt and the boolean indicates whether the user text should be
echoed.
A sample call would thus be:
C{handler('title', 'instructions', [('Password:', False)])}.
The handler should return a list or tuple of answers to the server's
questions.
If the server requires multi-step authentication (which is very rare),
this method will return a list of auth types permissible for the next
step. Otherwise, in the normal case, an empty list is returned.
