Please tell me how you can change the code in VanitySearch, instead of looking for an address, I need to replace it with a search public key? That is, set the Gx point search function.
You need to add another
searchType called something like PUBLICKEY and then in VanitySearch::initPrefix() and other places you need to detect the new search type
here by looking for "0x" or "0X" at the beginning and add fields to the
PREFIX_ITEM structure for x point, y point and the private key number.
