NoMorePass python libraries

Installation

Install pipenv

pip install pipenv

Requirements

We use pipenv, the requierements are included in Pipfile for the test

For example, to execute the receive password test:

pipenv install
pipenv run python testlocal.py

Usage

To receive a password:

from nomorepass.core import NoMorePass
import qrcode

nmp = NoMorePass()
qrtext = nmp.getQrText ('misitio')
#Show qr
img = qrcode.make(qrtext)
img.show()
#Wait for password
res = nmp.start()
if ('error' in res):
    print "Error: "+res["error"]
else:
    #Pass received
    print "Usuario: "+res["user"]
    print "Password: "+res["password"]
    print "Extra: "+res["extra"]

To send a password:

from nomorepass.core import NoMorePass
import qrcode

user = 'the user you want to send'
password = 'te password you want to send'
site = 'the site for the password'

nmp = NoMorePass()
qrtext = nmp.getQrSend(site,user,password,{'type':'pwd'})
#Show the qr
img = qrcode.make(qrtext)
img.show()
#wait for app receive the pass
res = nmp.send()
if ('error' in res):
    print "Error: "+res["error"]
else:
    #password sent
    print "Password received"
    print "Please, close the qr window"

Examples

testlocal.py

The local example display a qr-code and waits to scan it with nomorepass app, then it shows by console the data received (using secure nomorepass-protocol2). The window containing the qr is not closed by the program, you should close manually.

testsend.py

This example generates a unique Qr to send a password securely to a phone (one time use and using protocol2)

Send password to app

positional arguments:
  site                 site identification

optional arguments:
  -h, --help           show this help message and exit
  --user USER          username to send
  --password PASSWORD  password to send

test.py

The complete example is designed to work in a Raspberry pi with a TFT screen controlled by ST7735 attached. To install follow this instructions:

  1. Install https://github.com/cskau/Python_ST7735
sudo apt-get update
sudo apt-get install build-essential python-dev python-smbus python-pip python-imaging python-numpy

For a Raspberry Pi make sure you have the RPi.GPIO and Adafruit GPIO libraries by executing:

sudo pip install RPi.GPIO
sudo pip install Adafruit_GPIO

Install the library by downloading with the download link on the right, unzipping the archive, navigating inside the library's directory and executing:

sudo python setup.py install
  1. Connect Raspberry pi to display (see pinout):
TFT   -- RASPBERRY
------------------
LED   -- 3.3v (or other pin to switch on/off screen)
SCK   -- SCLK
SDA   -- MOSI
A0    -- GPIO24
RESET -- GPIO25
CS    -- CE0
GND   -- GND
VCC   -- 3.3v

Attach an additional push button between pin GPIO27 (and GND)

Use pin GPIO17 and GPIO18 as output

Run the test

python test.py
