## What it is
BitCrack is a C++ command-line tool for brute-forcing Bitcoin private keys using CUDA (NVIDIA) or OpenCL (AMD/Intel) GPU acceleration. It was created primarily to help solve the Bitcoin puzzle transaction, a set of addresses with increasingly difficult keys.

## Use cases
- crack a bitcoin puzzle address private key
- brute force bitcoin private keys on gpu
- search a keyspace range for a bitcoin address
- run distributed key search shares across machines
- resume an interrupted private key search

## When to choose
- you need GPU-accelerated brute forcing of specific Bitcoin addresses
- you want to participate in solving the Bitcoin puzzle transactions
- you need keyspace range control, checkpointing, or work sharing in a key search

## When to avoid
- you need general-purpose cryptocurrency mining
- you lack a CUDA or OpenCL capable GPU
- you expect reliable OpenCL support on AMD or Intel devices, which is documented as experimental and buggy

## Facets
- artifact type: cli-tool
- maturity: active
- function: cryptography, security, gpu-computing, cli
- domain: security, gpu-computing
- platform: windows, cpp
- tags: bitcoin, brute-force, opencl, cuda, private-keys, puzzle-solving, cryptocurrency, linux
