This is wip sfv checker It is not stable i wouldn't recommend you to use. It uses CRCpp library for crc32 calculation. I shaved this library to fit my needs. https://github.com/d-bahr/CRCpp What QtSfv does for now: - Uses Qt6/5 for it's gui and cross platform compability - Utilizes threads in order to speed up crc32 calculation - Uses C++20 I planned these features for QtSfv - Better UX/UI - Faster CRC32 calculations with less memory requirements - Shell extension for win32
