frank2 on 4:37 AM 09/04/2023: @nightxyz Hilariously that's a test key I used during the creation of this puzzle. Now try creating a keygen!

nightxyz on 6:05 PM 09/04/2023: @frank2 Too many mathematics... I have no time to solve and write a keygen but i can supply second key : NNNN-NNNN-UQYU-NKHF There is no keygen requirement in challenge summary. Maybe someone else digs deeper. Password is 19 characters long included - sign. First 8 characters are taken and derived second 8 characters using character array "OFCKANLUPEQDHXTYWBMImqXagNiZJWlEFSydocHP". I found second part from memory before go/nogo intersection.
