[crypto in c++] i do really need help guys..

hi everyone..
thanks for reading..

these are my problem:
i've no idea how to read or load shapefile in c++ (do i need database or kind
of it),
then it needs to be encryped with AES,
and i dont know either what's the suitable GUI for that.

i hope all the experienced here could help me soon,

thanks guys,
god bless you,
