Name: python-pycrypto
Version: 2.6.1
Release: 1
Summary: Cryptographic modules for Python.
License: Public domain
URL: http://www.pycrypto.org/
Source0: https://mirrors.nju.edu.cn/pypi/web/packages/60/db/645aa9af249f059cc3a368b118de33889219e0362141e75d4eaf6f80f163/pycrypto-2.6.1.tar.gz
BuildArch: noarch
%description
This is a collection of both secure hash functions (such as SHA256 and
RIPEMD160), and various encryption algorithms (AES, DES, RSA, ElGamal,
etc.). The package is structured to make adding new modules easy.
This section is essentially complete, and the software interface will
almost certainly not change in an incompatible way in the future; all
that remains to be done is to fix any bugs that show up. If you
encounter a bug, please report it in the Launchpad bug tracker at
https://launchpad.net/products/pycrypto/+bugs
An example usage of the SHA256 module is:
>>> from Crypto.Hash import SHA256
>>> hash = SHA256.new()
>>> hash.update('message')
>>> hash.digest()
'\xabS\n\x13\xe4Y\x14\x98+y\xf9\xb7\xe3\xfb\xa9\x94\xcf\xd1\xf3\xfb"\xf7\x1c\xea\x1a\xfb\xf0+F\x0cm\x1d'
An example usage of an encryption algorithm (AES, in this case) is:
>>> from Crypto.Cipher import AES
>>> obj = AES.new('This is a key123', AES.MODE_CBC, 'This is an IV456')
>>> message = "The answer is no"
>>> ciphertext = obj.encrypt(message)
>>> ciphertext
'\xd6\x83\x8dd!VT\x92\xaa`A\x05\xe0\x9b\x8b\xf1'
>>> obj2 = AES.new('This is a key123', AES.MODE_CBC, 'This is an IV456')
>>> obj2.decrypt(ciphertext)
'The answer is no'
One possible application of the modules is writing secure
administration tools. Another application is in writing daemons and
servers. Clients and servers can encrypt the data being exchanged and
mutually authenticate themselves; daemons can encrypt private data for
added security. Python also provides a pleasant framework for
prototyping and experimentation with cryptographic algorithms; thanks
to its arbitrary-length integers, public key algorithms are easily
implemented.
As of PyCrypto 2.1.0, PyCrypto provides an easy-to-use random number
generator:
>>> from Crypto import Random
>>> rndfile = Random.new()
>>> rndfile.read(16)
'\xf7.\x838{\x85\xa0\xd3>#}\xc6\xc2jJU'
A stronger version of Python's standard "random" module is also
provided:
>>> from Crypto.Random import random
>>> random.choice(['dogs', 'cats', 'bears'])
'bears'
Caveat: For the random number generator to work correctly, you must
call Random.atfork() in both the parent and child processes after
using os.fork()
