Implement software registration by using MAC address in Delphi
HE Ding-hu · Microcomputer Information · 2011
The MAC address of network card is unique global. Software registration can be actualized by using this property. First the client application read out the MAC address of network card and encrypt. Then the server will revert the code to MAC address ,use it to build software sequence number and provide it for the client application. At last the client application use sequence number to build the MAC address after decipherment and compare it to the local MAC address to confirm whether the software is legal. If the software is legal,the MAC address of network card will be written in registry. If not, the client application will be terminated by force.
