SimpleBitID
v0.05
Copyright (C) 2014  Antoine FERRON


This is a really basic client for BitID protocol for PC.
There is a one-click installer for Windows (XP, 2k, Vista, 7, 8 & 8.1).
Minimal but easy to use. The main goal is to provide API in
python for a client implementation of the BitID protocol.


 Windows Install :
Just install the exe (in release) and enjoy!

 Linux or MacOSX install:
- Be sure you have python 2.7 installed
- Download the tar.gz in release
- Uncompress it
- register "bitid" protocol to call something like:
	"python2.7 /dir-to-simplebitiD/SimplebitID.py %s" 
Note that in Linux, the window manager is responsible for that.
So it depends if you have Gnome, KDE or XFCE, LXDE, etc...
It can be also added directly in the web browser sometimes.

	
 Usage :
When clicking on a "bitid://" link in your browser,
it will launch SimpleBitID and identify you.

 More details abour SimpleBitID :
No GUI for now. Just use a 256 bits key in your
user directory. 

At startup, it generates your private key in
%APPDATA%\SimpleBitID
This file contains private key in ascii-hex (without "0x").
You can import your own key in converting and putting it
in this file.

ECDSA uses random "k", not deterministic signing.

Random source for key generation or signing is :
CryptGenRandom in Windows
/dev/urandom   in Unix-like

For RFC6979 signature, you can check ECDSA_BTC.py in Fast_Sign_Verify 


 Possible improvements:
- PIN or password to read private key file (AES encrytion)
- GUI
- Easy install in Linux and MacOSX
- Use other random sources
- Determinstic ECDSA (RFC 6979)
- Key Import and Export


 Compilation : make of bin installer in Windows:
1) Needs
- Python 2.7.6 32bits
- py2exe 0.6.9 Win32 py27
- 7zip 9.2
- 7zip SFX Builder 2.0.5
2) Edit BUILD.dat
To point to the right directory of python, 7zip & 7zSfxB
3) Launch BUILD.dat
Edit SFX_data or change info in 7zSfxB if you want
4) At the end, one new exe is created which is Win installer.
