An error when executing pycrypto

Question

I work with odoo and I want to install the module of paybox : this one : https://bitbucket.org/anybox/anybox_paybox/ For that : this module needs pycrypto to work

So, I installed pycrypto in the linux server (ubuntu)

1. git clone https://github.com/dlitz/pycrypto.git
2. ./configure
3. python setup.py build
4. python setup.py install

and I made this test : python setup.py test Result there is no error but the problem comes here : in this file //paybox_signature.py//

# coding: utf-8
import urllib
import base64
from Crypto.PublicKey import RSA
from Crypto.Signature import PKCS1_v1_5
from Crypto.Hash import SHA

class Signature():

def verify(self, signature, msg, key):
    """ check if the signature is correct according to the public key path         given
        and the message """
    msg = self.remove_sign(msg)
    key = RSA.importKey(key)
    ha = SHA.SHA1Hash().new(msg)
    verifier = PKCS1_v1_5.new(key)
    signature = urllib.unquote(signature)
    signature = base64.b64decode(signature)
    return verifier.verify(ha, signature)

    def remove_sign(self, msg):
    """ remove signature arg from the given string"""
    pos = msg.find('&Signature')
    if pos == -1:
        return msg
    return msg[:pos] 

when I execute this line of the file :

from Crypto.PublicKey import RSA

--> It ok there is no error

when I do this

from Crypto.Signature import PKCS1_v1_5

--> Traceback (most recent call last): File "", line 1, in ImportError: No module named Signature

I don't know Why All the modules are there why python make this error !! really I don't know Please I need your help Thank you

Answer 1

Might be issue with the pycrypto package installation.

try with

sudo easy_install pycrypto

and than reboot your system.

You may also checkout api of pycrypto

If you use Mac OS than see more discussion here

Its an old question but for people who are still looking for answer and stumbling upon this page. You can download the pyCrypto from pycrypto dist, but I recommend "pip install pyCrypto" as its simple and better.
