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.

JetstreamDB is a universal filesystem, cache, memory, database. It is a component to build into solutions for management consulting customers. It has been running in production since April 2023. The logo was inspired by the tea clipper. It intends to be a great data store without AI like tea clippers took the seas before ironclads.

It is an open-source component, but we offer paid services with audit, system security reviews, benchmarking, and warranty. Jetstreamdb is available up to 6 TB low latency RAM with optional extra 50 TB SSD configurations for about $150/hr. https://calendly.com/hq-schmied/30min
