#187938 - PIN + PUK Responding to: ???'s previous message |
It's basically the PIN code for end-user and PUK code for the fool who changed and forgot.
The PIN code for memory, and the PUK code for safe storage somewhere else. But the term master code is actually used even when being different for every installation. Think about a lock for many employees. They all have their individual PIN. But the system also have a master code, which is used for gaining access and add/remove the individual PIN codes. Having a master code formed mathematically from a serial number is doable. But the bad thing is that you don't want someone to figure out (or steal) that formula. A factory that sends out 1000 locks should basically create 1000 totally random master codes, so there are no way to take the knowledge of 10 locks and apply to the eleventh. |
