This can be used, for example, to implement lazy translation functions that
delay the actual translation until the string is actually used. The
rationale for such behavior is that the locale of the user may not always
be available. In web applications, you only know the locale when processing
a request.
The proxy implementation attempts to be as complete as possible, so that
the lazy objects should mostly work as expected, for example for sorting:
>>> greetings = [
... LazyProxy(greeting, 'world'),
... LazyProxy(greeting, 'Joe'),
... LazyProxy(greeting, 'universe'),
... ]
>>> greetings.sort()
>>> for greeting in greetings:

Associating an arbitrarily high number of listeners without explicitly

events to be run are present inside of a mutable collection
that can't be changed during iteration.
Event registration and removal is not intended to be a "high
velocity" operation; it is a configurational operation. For
systems that need to quickly associate and deassociate with
events at high scale, use a mutable structure that is handled
from inside of a single listener.

"""
Map values using input correspondence (a dict, Series, or function).
Maps the values (their categories, not the codes) of the index to new
categories. If the mapping correspondence is one-to-one the result is a
:class:`~pandas.CategoricalIndex` which has the same order property as
the original, otherwise an :class:`~pandas.Index` is returned.
If a `dict` or :class:`~pandas.Series` is used any unmapped category is
mapped to `NaN`. Note that if this happens an :class:`~pandas.Index`
will be returned.
Parameters
----------
mapper : function, dict, or Series
Mapping correspondence.
Returns
-------
pandas.CategoricalIndex or pandas.Index
Mapped index.
See Also
--------
Index.map : Apply a mapping correspondence on an
:class:`~pandas.Index`.
Series.map : Apply a mapping correspondence on a
:class:`~pandas.Series`.
Series.apply : Apply more complex functions on a
:class:`~pandas.Series`.
Examples
--------
>>> idx = pd.CategoricalIndex(['a', 'b', 'c'])
>>> idx
CategoricalIndex(['a', 'b', 'c'], categories=['a', 'b', 'c'],
ordered=False, dtype='category')
>>> idx.map(lambda x: x.upper())
CategoricalIndex(['A', 'B', 'C'], categories=['A', 'B', 'C'],
ordered=False, dtype='category')
>>> idx.map({'a': 'first', 'b': 'second', 'c': 'third'})
CategoricalIndex(['first', 'second', 'third'], categories=['first',
'second', 'third'], ordered=False, dtype='category')
If the mapping is one-to-one the ordering of the categories is
preserved:
>>> idx = pd.CategoricalIndex(['a', 'b', 'c'], ordered=True)
>>> idx
CategoricalIndex(['a', 'b', 'c'], categories=['a', 'b', 'c'],
ordered=True, dtype='category')
>>> idx.map({'a': 3, 'b': 2, 'c': 1})
CategoricalIndex([3, 2, 1], categories=[3, 2, 1], ordered=True,
dtype='category')
If the mapping is not one-to-one an :class:`~pandas.Index` is returned:
>>> idx.map({'a': 'first', 'b': 'second', 'c': 'first'})
Index(['first', 'second', 'first'], dtype='object')
If a `dict` is used, all unmapped categories are mapped to `NaN` and
the result is an :class:`~pandas.Index`:

"""Manager for questions to be shown in the statusbar.
The way in which multiple questions are handled deserves some explanation.
If a question is blocking, we *need* to ask it immediately, and can't wait
for previous questions to finish. We could theoretically ask a blocking
question inside of another blocking one, so in ask_question we simply save
the current prompt state on the stack, let the user answer the *most
recent* question, and then restore the previous state.
With a non-blocking question, things are a bit easier. We simply add it to
self._queue if we're still busy handling another question, since it can be
answered at any time.
In either case, as soon as we finished handling a question, we call
_pop_later() which schedules a _pop to ask the next question in _queue. We
schedule it rather than doing it immediately because then the order of how
things happen is clear, e.g. on_mode_left can't happen after we already set
up the *new* question.
Class Attributes:
KEY_MODES: A mapping of PromptModes to KeyModes.
Attributes:

_loops: A list of local EventLoops to spin in when blocking.
_queue: A deque of waiting questions.

Interface to the dot language
=============================
The B{Dot} module provides a simple interface to the
file format used in the U{graphviz<http://www.research.att.com/sw/tools/graphviz/>}
program. The module is intended to offload the most tedious part of the process
(the B{dot} file generation) while transparently exposing most of its features.
To display the graphs or to generate image files the U{graphviz<http://www.research.att.com/sw/tools/graphviz/>}
package needs to be installed on the system, moreover the C{dot} and C{dotty} programs must
be accesible in the program path so that they can be ran from processes spawned
within the module. See the L{Dot} documentation for further information on the setup.
Example usage
-------------
Here is a typical usage::
from altgraph import Graph, Dot
# create a graph
edges = [ (1,2), (1,3), (3,4), (3,5), (4,5), (5,4) ]
graph = Graph.Graph(edges)
# create a dot representation of the graph
dot = Dot.Dot(graph)
# display the graph
dot.display()
# save the dot representation into the mydot.dot file
dot.save_dot(file_name='mydot.dot')
# save dot file as gif image into the graph.gif file
dot.save_img(file_name='graph', file_type='gif')
Customizing the output
----------------------
The graph drawing process may be customized by passing
valid B{dot} parameters for the nodes and edges. For a list of all
parameters see the U{graphviz<http://www.research.att.com/sw/tools/graphviz/>}
documentation.
Example::
# customizing the way the overall graph is drawn
dot.style(size='10,10', rankdir='RL', page='5, 5' , ranksep=0.75)
# customizing node drawing
dot.node_style(1, label='BASE_NODE',shape='box', color='blue' )
dot.node_style(2, style='filled', fillcolor='red')
# customizing edge drawing
dot.edge_style(1, 2, style='dotted')
dot.edge_style(3, 5, arrowhead='dot', label='binds', labelangle='90')
dot.edge_style(4, 5, arrowsize=2, style='bold')
B{Observation}: dotty (invoked via L{Dot.display}) may not be able to
display all graphics styles. To verify the output save it to an image file
and look at it that way.
Valid attributes
----------------
- dot styles, passed via the L{Dot.style} method::
rankdir = 'LR' (draws the graph horizontally, left to right)
ranksep = number (rank separation in inches)
- node attributes, passed via the L{Dot.node_style} method::
style = 'filled' | 'invisible' | 'diagonals' | 'rounded'
shape = 'box' | 'ellipse' | 'circle' | 'point' | 'triangle'
- edge attributes, passed via the L{Dot.edge_style} method::
style = 'dashed' | 'dotted' | 'solid' | 'invis' | 'bold'
arrowhead = 'box' | 'crow' | 'diamond' | 'dot' | 'inv' | 'none' | 'tee' | 'vee'
weight = number (the larger the number the closer the nodes will be)
- valid U{graphviz colors<http://www.research.att.com/~erg/graphviz/info/colors.html>}
- for more details on how to control the graph drawing process see the
U{graphviz reference <http://www.research.att.com/sw/tools/graphviz/refs.html>}.

allowing a fine grained control over how the graph is being
displayed.
If the C{dot} and C{dotty} programs are not in the current system path
their location needs to be specified in the L{constructor<__init__>}.
For detailed example usage see the L{Dot} module documentation.

Performs shift cipher encryption on plaintext msg, and returns the

Notes
=====
The shift cipher is also called the Caesar cipher, after
Julius Caesar, who, according to Suetonius, used it with a
shift of three to protect messages of military significance.
Caesar's nephew Augustus reportedly used a similar cipher, but
with a right shift of 1.
ALGORITHM:
INPUT:
``key``: an integer (the secret key)
``msg``: plaintext of upper-case letters
OUTPUT:
``ct``: ciphertext of upper-case letters
STEPS:
0. Number the letters of the alphabet from 0, ..., N
1. Compute from the string ``msg`` a list ``L1`` of
corresponding integers.
2. Compute from the list ``L1`` a new list ``L2``, given by
adding ``(k mod 26)`` to each element in ``L1``.
3. Compute from the list ``L2`` a string ``ct`` of
corresponding letters.
Examples
========
>>> from sympy.crypto.crypto import encipher_shift, decipher_shift
>>> msg = "GONAVYBEATARMY"
>>> ct = encipher_shift(msg, 1); ct
'HPOBWZCFBUBSNZ'
To decipher the shifted text, change the sign of the key:
>>> encipher_shift(ct, -1)
'GONAVYBEATARMY'
There is also a convenience function that does this with the
original key:

######## affine cipher examples ############
def encipher_affine(msg, key, symbols=None, _inverse=False):
r"""
Performs the affine cipher encryption on plaintext ``msg``, and
returns the ciphertext.
Encryption is based on the map `x \rightarrow ax+b` (mod `N`)
where ``N`` is the number of characters in the alphabet.
Decryption is based on the map `x \rightarrow cx+d` (mod `N`),
where `c = a^{-1}` (mod `N`) and `d = -a^{-1}b` (mod `N`).
In particular, for the map to be invertible, we need
`\mathrm{gcd}(a, N) = 1` and an error will be raised if this is
not true.
Notes
=====
This is a straightforward generalization of the shift cipher with
the added complexity of requiring 2 characters to be deciphered in
order to recover the key.
ALGORITHM:
INPUT:
``msg``: string of characters that appear in ``symbols``
``a, b``: a pair integers, with ``gcd(a, N) = 1``
(the secret key)
``symbols``: string of characters (default = uppercase
letters). When no symbols are given, ``msg`` is converted
to upper case letters and all other charactes are ignored.
OUTPUT:
``ct``: string of characters (the ciphertext message)
STEPS:
0. Number the letters of the alphabet from 0, ..., N
1. Compute from the string ``msg`` a list ``L1`` of
corresponding integers.
2. Compute from the list ``L1`` a new list ``L2``, given by
replacing ``x`` by ``a*x + b (mod N)``, for each element
``x`` in ``L1``.
3. Compute from the list ``L2`` a string ``ct`` of
corresponding letters.

only be recovered by determining the mapping for each symbol.

Notes
=====
The Vigenère cipher is named after Blaise de Vigenère, a sixteenth
century diplomat and cryptographer, by a historical accident.
Vigenère actually invented a different and more complicated cipher.
The so-called *Vigenère cipher* was actually invented
by Giovan Batista Belaso in 1553.
This cipher was used in the 1800's, for example, during the American
Civil War. The Confederacy used a brass cipher disk to implement the
Vigenère cipher (now on display in the NSA Museum in Fort
Meade) [1]_.
The Vigenère cipher is a generalization of the shift cipher.
Whereas the shift cipher shifts each letter by the same amount
(that amount being the key of the shift cipher) the Vigenère
cipher shifts a letter by an amount determined by the key (which is
a word or phrase known only to the sender and receiver).
For example, if the key was a single letter, such as "C", then the
so-called Vigenere cipher is actually a shift cipher with a
shift of `2` (since "C" is the 2nd letter of the alphabet, if
you start counting at `0`). If the key was a word with two
letters, such as "CA", then the so-called Vigenère cipher will
shift letters in even positions by `2` and letters in odd positions
are left alone (shifted by `0`, since "A" is the 0th letter, if
you start counting at `0`).
ALGORITHM:
INPUT:
``msg``: string of characters that appear in ``symbols``
(the plaintext)
``key``: a string of characters that appear in ``symbols``
(the secret key)
``symbols``: a string of letters defining the alphabet
OUTPUT:
``ct``: string of characters (the ciphertext message)
STEPS:
0. Number the letters of the alphabet from 0, ..., N
1. Compute from the string ``key`` a list ``L1`` of
corresponding integers. Let ``n1 = len(L1)``.
2. Compute from the string ``msg`` a list ``L2`` of
corresponding integers. Let ``n2 = len(L2)``.
3. Break ``L2`` up sequencially into sublists of size
``n1``; the last sublist may be smaller than ``n1``
4. For each of these sublists ``L`` of ``L2``, compute a
new list ``C`` given by ``C[i] = L[i] + L1[i] (mod N)``
to the ``i``-th element in the sublist, for each ``i``.
5. Assemble these lists ``C`` by concatenation into a new
list of length ``n2``.
6. Compute from the new list a string ``ct`` of
corresponding letters.
Once it is known that the key is, say, `n` characters long,
frequency analysis can be applied to every `n`-th letter of
the ciphertext to determine the plaintext. This method is
called *Kasiski examination* (although it was first discovered
by Babbage). If they key is as long as the message and is
comprised of randomly selected characters -- a one-time pad -- the
message is theoretically unbreakable.
The cipher Vigenère actually discovered is an "auto-key" cipher
described as follows.
ALGORITHM:
INPUT:
``key``: a string of letters (the secret key)
``msg``: string of letters (the plaintext message)
OUTPUT:
``ct``: string of upper-case letters (the ciphertext message)
STEPS:
0. Number the letters of the alphabet from 0, ..., N
1. Compute from the string ``msg`` a list ``L2`` of
corresponding integers. Let ``n2 = len(L2)``.
2. Let ``n1`` be the length of the key. Append to the
string ``key`` the first ``n2 - n1`` characters of
the plaintext message. Compute from this string (also of
length ``n2``) a list ``L1`` of integers corresponding
to the letter numbers in the first step.
3. Compute a new list ``C`` given by
``C[i] = L1[i] + L2[i] (mod N)``.
4. Compute from the new list a string ``ct`` of letters
corresponding to the new integers.
To decipher the auto-key ciphertext, the key is used to decipher
the first ``n1`` characters and then those characters become the
key to decipher the next ``n1`` characters, etc...:
>>> m = AZ('go navy, beat army! yes you can'); m
'GONAVYBEATARMYYESYOUCAN'
>>> key = AZ('gold bug'); n1 = len(key); n2 = len(m)
>>> auto_key = key + m[:n2 - n1]; auto_key
'GOLDBUGGONAVYBEATARMYYE'
>>> ct = encipher_vigenere(m, auto_key); ct
'MCYDWSHKOGAMKZCELYFGAYR'
>>> n1 = len(key)
>>> pt = []
>>> while ct:
... part, ct = ct[:n1], ct[n1:]
... pt.append(decipher_vigenere(part, key))
... key = pt[-1]
...
>>> ''.join(pt) == m
True

def encipher_hill(msg, key, symbols=None, pad="Q"):
r"""
Return the Hill cipher encryption of ``msg``.
Notes
=====
The Hill cipher [1]_, invented by Lester S. Hill in the 1920's [2]_,
was the first polygraphic cipher in which it was practical
(though barely) to operate on more than three symbols at once.
The following discussion assumes an elementary knowledge of
matrices.
First, each letter is first encoded as a number starting with 0.
Suppose your message `msg` consists of `n` capital letters, with no
spaces. This may be regarded an `n`-tuple M of elements of
`Z_{26}` (if the letters are those of the English alphabet). A key
in the Hill cipher is a `k x k` matrix `K`, all of whose entries
are in `Z_{26}`, such that the matrix `K` is invertible (i.e., the
linear transformation `K: Z_{N}^k \rightarrow Z_{N}^k`
is one-to-one).
ALGORITHM:
INPUT:
``msg``: plaintext message of `n` upper-case letters
``key``: a `k x k` invertible matrix `K`, all of whose
entries are in `Z_{26}` (or whatever number of symbols
are being used).
``pad``: character (default "Q") to use to make length
of text be a multiple of ``k``
OUTPUT:
``ct``: ciphertext of upper-case letters
STEPS:
0. Number the letters of the alphabet from 0, ..., N
1. Compute from the string ``msg`` a list ``L`` of
corresponding integers. Let ``n = len(L)``.
2. Break the list ``L`` up into ``t = ceiling(n/k)``
sublists ``L_1``, ..., ``L_t`` of size ``k`` (with
the last list "padded" to ensure its size is
``k``).
3. Compute new list ``C_1``, ..., ``C_t`` given by
``C[i] = K*L_i`` (arithmetic is done mod N), for each
``i``.
4. Concatenate these into a list ``C = C_1 + ... + C_t``.
5. Compute from ``C`` a string ``ct`` of corresponding
letters. This has length ``k*t``.

r"""
Performs the Bifid cipher encryption on plaintext ``msg``, and
returns the ciphertext.
This is the version of the Bifid cipher that uses the `5 \times 5`
Polybius square. The letter "J" is ignored so it must be replaced
with something else (traditionally an "I") before encryption.
Notes
=====
The Bifid cipher was invented around 1901 by Felix Delastelle.
It is a *fractional substitution* cipher, where letters are
replaced by pairs of symbols from a smaller alphabet. The
cipher uses a `5 \times 5` square filled with some ordering of the
alphabet, except that "J" is replaced with "I" (this is a so-called
Polybius square; there is a `6 \times 6` analog if you add back in
"J" and also append onto the usual 26 letter alphabet, the digits
0, 1, ..., 9).
According to Helen Gaines' book *Cryptanalysis*, this type of cipher
was used in the field by the German Army during World War I.
ALGORITHM: (5x5 case)
INPUT:
``msg``: plaintext string; converted to upper case and
filtered of anything but all letters except J.
``key``: short string for key; non-alphabetic letters, J
and duplicated characters are ignored and then, if the
length is less than 25 characters, it is padded with other
letters of the alphabet (in alphabetical order).
OUTPUT:
ciphertext (all caps, no spaces)
STEPS:
0. Create the `5 \times 5` Polybius square ``S`` associated
to ``key`` as follows:
a) moving from left-to-right, top-to-bottom,
place the letters of the key into a `5 \times 5`
matrix,
b) if the key has less than 25 letters, add the
letters of the alphabet not in the key until the
`5 \times 5` square is filled.
1. Create a list ``P`` of pairs of numbers which are the
coordinates in the Polybius square of the letters in
``msg``.
2. Let ``L1`` be the list of all first coordinates of ``P``
(length of ``L1 = n``), let ``L2`` be the list of all
second coordinates of ``P`` (so the length of ``L2``
is also ``n``).
3. Let ``L`` be the concatenation of ``L1`` and ``L2``
(length ``L = 2*n``), except that consecutive numbers
are paired ``(L[2*i], L[2*i + 1])``. You can regard
``L`` as a list of pairs of length ``n``.
4. Let ``C`` be the list of all letters which are of the
form ``S[i, j]``, for all ``(i, j)`` in ``L``. As a
string, this is the ciphertext of ``msg``.
Examples
========
>>> from sympy.crypto.crypto import (
... encipher_bifid5, decipher_bifid5)
"J" will be omitted unless it is replaced with somthing else:

def kid_rsa_public_key(a, b, A, B):
r"""
Kid RSA is a version of RSA useful to teach grade school children
since it does not involve exponentiation.
Alice wants to talk to Bob. Bob generates keys as follows.
Key generation:
* Select positive integers `a, b, A, B` at random.
* Compute `M = a b - 1`, `e = A M + a`, `d = B M + b`,
`n = (e d - 1)//M`.
* The *public key* is `(n, e)`. Bob sends these to Alice.
* The *private key* is `(n, d)`, which Bob keeps secret.
Encryption: If `p` is the plaintext message then the
ciphertext is `c = p e \pmod n`.
Decryption: If `c` is the ciphertext message then the
plaintext is `p = c d \pmod n`.

Notes
=====
S. Golomb [G]_ gives a list of three statistical properties a
sequence of numbers `a = \{a_n\}_{n=1}^\infty`,
`a_n \in \{0,1\}`, should display to be considered
"random". Define the autocorrelation of `a` to be
.. math::
C(k) = C(k,a) = \lim_{N\rightarrow \infty} {1\over N}\sum_{n=1}^N (-1)^{a_n + a_{n+k}}.
In the case where `a` is periodic with period
`P` then this reduces to
.. math::
C(k) = {1\over P}\sum_{n=1}^P (-1)^{a_n + a_{n+k}}.
Assume `a` is periodic with period `P`.
- balance:
.. math::
\left|\sum_{n=1}^P(-1)^{a_n}\right| \leq 1.
- low autocorrelation:
.. math::
C(k) = \left\{ \begin{array}{cc} 1,& k = 0,\\ \epsilon, & k \ne 0. \end{array} \right.
(For sequences satisfying these first two properties, it is known
that `\epsilon = -1/P` must hold.)
- proportional runs property: In each period, half the runs have
length `1`, one-fourth have length `2`, etc.
Moreover, there are as many runs of `1`'s as there are of
`0`'s.

To use this class, create a new instance, passing a connected

If the handshake completes without raising an exception, then a TLS
connection has been negotiated. You can transfer data over this
connection as if it were a socket.
This class provides both synchronous and asynchronous versions of
its key functions. The synchronous versions should be used when
writing single-or multi-threaded code using blocking sockets. The
asynchronous versions should be used when performing asynchronous,
event-based I/O with non-blocking sockets.
Asynchronous I/O is a complicated subject; typically, you should
not use the asynchronous functions directly, but should use some
framework like asyncore or Twisted which TLS Lite integrates with
(see

This function performs a TLS/SRP handshake. SRP mutually
authenticates both parties to each other using only a
username and password. This function may also perform a
combined SRP and server-certificate handshake, if the server
chooses to authenticate itself with a certificate chain in
addition to doing SRP.
TLS/SRP is non-standard. Most TLS implementations don't
support it. See
U{http://www.ietf.org/html.charters/tls-charter.html} or
U{http://trevp.net/tlssrp/} for the latest information on
TLS/SRP.
Like any handshake function, this can be called on a closed
TLS connection, or on a TLS connection that is already open.
If called on an open connection it performs a re-handshake.
If the function completes without raising an exception, the
TLS connection will be open and available for data transfer.
If an exception is raised, the connection will have been
automatically closed (if it was ever open).
@type username: str
@param username: The SRP username.
@type password: str
@param password: The SRP password.
@type session: L{tlslite.Session.Session}
@param session: A TLS session to attempt to resume. This
session must be an SRP session performed with the same username
and password as were passed in. If the resumption does not
succeed, a full SRP handshake will be performed.
@type settings: L{tlslite.HandshakeSettings.HandshakeSettings}
@param settings: Various settings which can be used to control
the ciphersuites, certificate types, and SSL/TLS versions
offered by the client.
@type checker: L{tlslite.Checker.Checker}
@param checker: A Checker instance. This instance will be
invoked to examine the other party's authentication
credentials, if the handshake completes succesfully.
@type async: bool
@param async: If False, this function will block until the
handshake is completed. If True, this function will return a
generator. Successive invocations of the generator will
return 0 if it is waiting to read from the socket, 1 if it is
waiting to write to the socket, or will raise StopIteration if
the handshake operation is completed.
