BTCRECOVER GUIDE for BITCOIN CORE on win10 Q1-2016 with GPUs acceleration

First of all a big thank you to gurnec aka btchris (https://bitcointalk.org/index.php?action=profile;u=1171)

(to support him > 17LGpN2z62zp7RS825jXwYtE7zZ19Mxxu8)

Now this guide will first be a report of my progress (and difficulties) in solving the problem that we have
(otherwise you wouldn't be reading it). All tools will be updated around the 02.28.2016 and downloadable on a torrent zip and with their links at the date of this writing.

Moreover it will be a complement and easy version of this:

STEP 1 INSTALLATION OF BTCRECOVER according to https://github.com/gurnec/btcrecover/blob/master/docs/INSTALL.md

>python 2.7.11 x86
https://www.python.org/ftp/python/2.7.11/python-2.7.11.msi

>scrypt

1. Open a command prompt window, and type this to install pylibscrypt:

C:\Python27\Scripts\pip install pylibscrypt

2. Download and rename

https://download.libsodium.org/libsodium/releases/libsodium-1.0.2-msvc.zip

Copy Win32\Release\v120\dynamic\libsodium.dll file into your C:\Python27 directory,
and rename it to sodium.dll

3. Download visual c++

>google protocol buffer

Open a command prompt window, and type this to install

C:\Python27\Scripts\pip install pyprotobuf

>gpu acceleration

As this guide is a work in progress I have difficulties, here is the begining.

1. PyOpenCL

The latest binary version of PyOpenCL for Python 2 & Python(x,y)
available here: https://code.google.com/p/pythonxy/wiki/AdditionalPlugins.
(The download link on that page is a button to the right of “pyopencl”
 which has an arrow pointing downwards.)

This link doesn't work... I will try with this :


http ://ftp .ntua.gr/pub/devel/pythonxy/Python(x,y)-2.7.10.0.exe (remove 2 spaces at between http: and ftp.p because of suspicious link  ).

and this : https://wiki.tiker.net/PyOpenCL/Installation/Windows

and this : http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk

I chosed the 3.0 with the downloader and then only 32bits version. And installed the complete version.

2. NumPy https://sourceforge.net/projects/numpy/files/NumPy/1.11.0rc1/numpy-1.11.0rc1.zip/download

3. PyCrypto http[Suspicious link removed]


STEP 2 TESTING to https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#testing-your-config

Python X,Y is here now -> http://python-xy.github.io/

What exactly do you mean by GPU acceleration ? Are you talking about GPU mining ? Thanks.

Hey what's the status on this? Does it still work? Any success ever?

Hi,
How long does it take to use btcrecover to decrypt blocked blockchian.info?
Have you used it successfully?

Greatly depends on CPU speed and number of passwords you need to try. The most recent change to the script now shows the difficulty for each wallet[1]. For blockchain.info the algorithm used is based on sha1, which should be fairly quick on modern CPUs.
