VanitySearch is a tool designed for finding Bitcoin address prefixes. If you wish to generate a secure private key, please use the -s option to enter your passphrase; this passphrase will be used to generate a base key compliant with the BIP38 standard (e.g., VanitySearch.exe -s "my passphrase" 1MyPrefix). Alternatively, you can use the command VanitySearch.exe -ps "my passphrase", which incorporates an additional cryptographically secure seed into your passphrase. This update addresses bugs related to custom address matching and private key conversion, replaces the random number generator, introduces new search puzzles tailored to specific finite regions, and adds both "random" and "incremental" search modes. Furthermore, the -e option has been added to enable homomorphic properties—a feature that has been completely reimplemented—while the integration of the AVX2 instruction set optimizes CPU performance and enhances underlying logic.

A high-performance CPU-based tool for searching compressed and uncompressed addresses, as well as puzzle-based private key and brainwallet searches. Commonly used in research projects such as Cyclone, Brainflayer, Keyhunt, BitCrack, Ecloop, Keyhunt CUDA, and BitCrack.For educational purposes

ZUC SM3 SM4 AVX2 optimized cryptographic algorithm implementation, about 6 times faster than some versions. And sm3 sm4 zuc cryptographic algorithm core implementation.

KeyKiller is designed to achieve extreme performance on modern NVIDIA GPUs, solving the Satoshi puzzle. It leverages CUDA, warp-level parallelism, and batched EC operations to push the boundaries of cryptographic key discovery. It is commonly used in research projects such as Secp256k1-CUDA,Brainflayer,BitCrack, Keyhunt CUDA BitCrack,RCKangaroo.

AES cryptographic library implemented in C/C++ with hardware acceleration using AES-NI and AVX2 instruction sets, and there is a generic version! They support AES-128, AES-192 and AES-256 bit key lengths, and multiple modes of operation: ECB, CBC, CTR, CFB128, OFB, GCM (basic building blocks).
