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.
