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
