HashNyx is top-tier CPU-powered multi-threaded password hash cracker written in C.It is designed for flexibility and speed,utilizing various optimization techniques to efficiently find matches for a given hash value.It can crack md5,sha1,sha2,sha3,ripemd160,keccak224 256 384 512,hash160,and more.

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.

Track AI spending across API providers, MCP tools, subscriptions, and self-hosted GPUs from your terminal. One CLI to see what you're actually paying — Anthropic, OpenAI, OpenRouter, vLLM on your own hardware — with real TCO math. Compare your self-hosted $/MTok vs cloud pricing. Local-first, no SaaS required.

Address to hash160 is an efficient multi-threaded tool designed to decode various cryptocurrency addresses (such as Bitcoin BTC,Bitcoin Cash BCH,Litecoin LTC,Bitcoin Gold BTG,etc.) to extract hash160 values. It is often used in research such as brainflayer,keyhunt,BitCrack,ecloop, keyhunt cuda,etc.

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

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.
