how 2 update a hasp????

the hasp password and ID is easily got . and the memory data in hasp dongle is easily got by the password and haspedit.exe too. after update the password(in the memory data file --*.hed), we may write the data to a new hasp dongle. but cuz software is bound with the old hasp password, it can't be run with new hasp dongle. so, we must update the hasp password to be new in the software. it seems to be difficult
