keyhunt

Tool for hunt privatekeys for crypto currencies that use secp256k1 elliptic curve

Post: https://bitcointalk.org/index.php?topic=5322040.0

Work for Bitcoin

• address compress or uncompress
• hashes rmd160 compress or uncompress
• publickeys compress or uncompress

Work for Ethereum

• address

TL:DR

• Download and build
• Run against puzzle 66 (address mode)

./keyhunt -m address -f tests/66.txt -b 66 -l compress -R -q -s 10

You need to add -t numberThreads to get better speed

• Run against Puzzle 125 (bsgs mode)

./keyhunt -m bsgs -f tests/125.txt -b 125 -q -s 10 -R

You need to add -t numberThreads and -k factor to get better speed

Free Code

This code is free of charge, see the licence for more details. https://github.com/albertobsd/keyhunt/blob/main/LICENSE

Although this project is a hobby for me, it still involves a considerable amount of work. If you would like to support this project, please consider donating at https://github.com/albertobsd/keyhunt#donations.

Disclaimer

I made this tool as a generic tool for the Puzzles. I recommend to everyone to stay in puzzles

Several of users request me to add support for ethereum and minikeys, I did it. But again i recommend only use this program for puzzles.

For regular users

Please read the CHANGELOG.md to see the new changes

Download and build

This program was made in a linux environment. if you are windows user i strongly recommend to use WSL enviroment on Windows. it is available in the Microsoft store

Please install on your system

• git
• build-essential

for legacy version also you are going to need:

• libssl-dev
• libgmp-dev

On Debian based systems, run this commands to update your current enviroment and install the tools needed to compile it

apt update && apt upgrade
apt install git -y
apt install build-essential -y
apt install libssl-dev -y
apt install libgmp-dev -y

To clone the repository

git clone https://github.com/albertobsd/keyhunt.git

don't forget change to the keyhunt directory (But i'm not here to teach you linux commands)

cd keyhunt

First compile:

make

if you have problems compiling the main version you can compile the legacy version

make legacy

and then execute with -h to see the help

./keyhunt -h

¡Beta!

This version is still a beta version, there are a lot of things that can be fail or improve. This version also could have some bugs. please report it.

Modes

Keyhunt can work in diferent ways at different speeds.

The current availables modes are:

• address
• rmd160
• xpoint
• bsgs

Experimental modes

• minikeys
• pub2rmd

address mode

This is the most basic approach to work, in this mode your text file need to have a list of the publicaddress to be search.

Example of address from solved puzzles, this file is already on the repository tests/1to32.txt

1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH
1CUNEBjYrCn2y1SdiUMohaKUi4wpP326Lb
...

To target that file we need to execute keyhunt with this line

./keyhunt -m address -f tests/1to32.txt -r 1:FFFFFFFF

output:

(Output omitted)

In this mode you can specify to seach only address compressed or uncompressed with -l compress or -l uncompress

Test your luck with the random parameter -R againts the puzzle #66

./keyhunt -m address -f tests/66.txt -b 66 -l compress -R -q -s 10

Please note the change from -r 1:FFFFFFFF to -b 66, with -b you can specify the bit range

vanity search.

To search only one vanity address is with 1Good1 or with 1MyKey use the next command

All the vanity address and his privatekeys will be saved in the file VANITYKEYFOUND.txt of your current directory

rmd160 mode

rmd stands for RIPE Message Digest (see https://en.wikipedia.org/wiki/RIPEMD )

mode rmd160 work in the same way than address, but the diference is that file need to have hash rmd160 instead of addresses.

example file tests/1to32.rmd :

751e76e8199196d454941c45d1b3a323f1433bd6
7dd65592d0ab2fe0d0257d571abf032cd9db93dc

9652d86bedf43ad264362e6e6eba6eb764508127
...

to target that file you need to execute the next line:

./keyhunt -m rmd160 -f tests/1to32.rmd -r 1:FFFFFFFF -l compress -s 5

output:

xpoint mode

This method can target the X value of the publickey in the same way that the tool search for address or rmd160 hash, this tool can search for the X values

The speed for this method is better than the speed for address or rmd160

The input file can had one publickey per line compress or uncompress:

• Publickey Compress (66 hexcharacters)
• Publickey Uncompress (130 hexcharacters)

Example input file:

A few substracted values from puzzle 40
