Bitcoin private key brute force tool, written in python. Also can be used as a bitcoin wallet generator.

Btcbf

Btcbf is a fast and efficient bitcoin private key brute force tool written in python. It works based on generating random or sequential private keys and their corresponding public address. Then checking the address through an online API or an offline database.

What makes Btcbf fast, is mainly the bit library. Thanks to its developer!

Quick Start

 $ git clone https://github.com/vlnahp/Btcbf.git

 $ cd Btcbf

 $ pip install -r requirements.txt

 $ python Btcbf.py or  $ python3 Btcbf.py on Linux

The Goal

The main goal is to prove bitcoin is secure. At least until the day that Quantum computers start working against it learn python!

There are also some useful tools implemented.

Requirements

In offline mode, a database is necessary. By default, it is address.txt containing some addresses. Let's be honest, searching online takes too long and the addresses with balance included in the program are too scarce (as having a current text file with all addresses would make this repository over 5GB). So the users who wish, can download the latest text file from here (direct link), rename and replace it with the "address.txt". But be careful about memory issues. Only use this database if you have sufficient RAM!

To install the requirements run the command below:

$ pip install -r requirements.txt

Usage

Just execute this command: $ python Btcbf.py or $ python3 Btcbf.py on Linux, Btcbf tells you what to do!

Type your desired action and follow instructions. (I love to interact with my program🙂)

Results will be saved to foundkey.txt in the main directory.

btcbf's Issues

Just curious

Just curious, how many addresses are generated and checked per second? I'm using the windows release on 6 cores and it's just zipping by. Using my own address.txt I put together too. Love how it's not lagging up my whole computer like other similar programs. :)

Crashes during online and offline brute force operation

Hi,

When I run the Python3 Btcbf.py command and follow all instructions, the program starts running but after a while it exits Terminal and reboots the system with no error message at all. What could be the issue? This happens with both offline and online brute force operation - I have my own address.txt file.

Thanks!

Btcbf.py won't run

Hello,

I used to have this running whilst on an older build of Windows. I am currently on Windows 11 23H2 and having some issues here.

All requirements installed successfully, i am also running Python 3.12

Any ideas on what the issue here could be?

Thank you.

Noob Issue

Hi
The program does not output well. How to fix it? I do not see any generated wallets.

error

Address.txt file question.

The address.txt file contains 3 types of bitcoin address - 1xxx, 3xxx and bc1.
Does the program generate and check all 3 types of address or just the basic 1xxx ?

About Uncompress and p2sh address

I have test result just out compress address, how can i modify code to uncompress, p2sh or both?
Many thanks.

Test of sequential mode fails.

I created an address.txt file with the first 10 compressed bitcoin addresses from here -

to test the program in sequential mode.

I ran the program with range = 1-100 and 1 core.

The program didn't find any of the addresses in the file - why is that?

How does it stop

Hi, When I start running let's say for brute-forcing offline it doesn't stop why is that happening?

Not supported between instances of 'str' and 'int"

How to use

Is there a process for use

Ram issue

I have been testing the script and discovered an issue with the RAM usage going up. If you run the script long enough the ram usage will slowly go up.

Tested the script inside a limited container. Not sure how much it goes up in what span of time.

Slow with large size data

With offline mode (my cpu):

• 1gb text data, speed of program is only about 30it/s
• 300kb text data speed is 10000it/s
  could you fix this problem?

Always run on 1 core CPU only

No matter how many cores I choose, it always runs on only one core.
It reflects on the Task Manager as well as the "current rate" metrics as well.

I guess that we need to use Process to achieve it?
from multiprocessing import cpu_count, Process

Reference: https://stackoverflow.com/questions/22700164/python-running-multiple-processes-simultaneously

How long does it take

How long does it take to get a private key? i brute force with 11000/s

Ok, the program works but what next?

Ok, the program works but what next?

How can I see if Btcbf is really working?

Hey! How this supouse to work?What should i see if its realy working?

Originally posted by @Werevalis in #12 (comment)

segwit & legacy keys

Hi! Is it possible to add algo for segwit & legacy address? Because I see that the script only works for addresses that begin with 1..., not for 3... and bc1.... thank you!

Foundkey

Foundkey.txt is created automatically by script after find private key?

This is not a issue but I want to ask

Where does the wallet with a positive balance go to?

When will sequential attack be released?

Any success stories from anyone here?

No issue to report as all is running smooth

Just wanted to see if people have had some good results here?

Curious is all!

How it verifies

What should we input in sequence field
DEC format
HEX format

I got an error

I got the same error even after changing from Python 3 to Python 2

Where are the results saved?

Where are the results saved? Does the program automatically create a folder?

Hi! What this "62"?

Offline bf random

Test result random

Hi, how can i make a test for random offline result ?
Thanks

Test

After the recent update I did a test with a known address in sequential brute force mode and it doesn't seem to work. No results found. Looks like it doesn't read adress.txt

If I make my own address database with only one address, will it just target that address?

Deriveing Bitcoin private key from it's p2sh-segwit address (p2sh p2wpkh)

Am going to share some details on how to get the private key from address.

I know you'll be thinking by now that the private key can't be derived from the address, that's what I thought on till I told my self nothing is impossible .
Now instead of you guys running brute force attack or try to reverse the algorithm why not create/find a different calculation that can be use to derive the address from the private key and then reverse your own calculation, now it may sound impossible looking at it this way f16dd077d18c6a2c64293da97cc84fad6e3ba8acc4079b32693a8e950fd0ce24 to 3MvhVPJesYH3teZ6eydZkdeMMGmjkQRF4M but after using the below script

from decimal import Decimal

user = input("1: Priv to position\n2: Position to priv\n3: Add to position\n4: Position to add\n[Ans]: ")

if user == '1':
   def find_position(hex_str):
       return int(hex_str, 16)+1

   key = input("\nkey: ")
   print ('Position:',find_position(key))

elif user == '2':
     def find_private_key(position):
         return hex(int(position) - 1)[2:].zfill(64)

     position = Decimal(input("\nPosition: "))
     private_key = find_private_key(position)
     print("Private Key:", private_key)

elif user == '3':
     def calculate_position(string):
         characters = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"
         base = len(characters)
         length = len(string)
         position = 0
         power = 1

         for i in range(length - 1, -1, -1):
             char = string[i]
             digit = characters.index(char)
             position += digit * power
             power *= base

         return position

     input_string = input("\n[address]: ")
     position = calculate_position(input_string)+1
     print(f"Position:",position)

elif user == '4':
     def calculate_address(position):
         characters = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"
         base = len(characters)
         address = ""

         while position > 0:
               position, remainder = divmod(position , base)
               address = characters[remainder] + address

         return address

     input_position = int(input("\nPosition: ")) - 1
     address = calculate_address(input_position)
     print("Address:", address)

else:
   print ('\nWrong input')

This how you should be looking at it 109201421632169861550405429025058298838764240157642115744110253215387890011685 to 36828257717136275917320730136896267955301102672325362318923 now it should look more vulnerable for your brain to comprehend.

Am not going to share the calculation/script I use in deriving the address from the private key but if you're planning on following the idea I just gave I want you to consider that

1. Nothing is impossible
2. It's not going to be an easy one (finding a different approach for deriveing the address from the private key)
3. Don't be afraid of errors or failure instead fine a way to solve the issue or find a different approach (you only fail when you stop trying)
4. Try to take a break(free your mind a bit)

If you have a calculation in mind but don't know how to implement it in python3 or any other programming language try using an Ai chatbot.

I will not be giving any prove on this

Not an issue

brother i wanted to add preset options for the remaining btc puzzles.
My question is how can i find the range in decimals from a hex private key

brute force

hey! where can i find the private keys that are cracked?
