My method is to obtain network card MAC address and the serial number of the hard disk, according to their produce a CRC!
And then generating sequence number of SN,

Question:

1, the serial number of SN and the CRC code validation of how to build a relationship to computer hardware

2, how to load the software used in SN length problem

CodePudding user response:

Read through the API to install the software of PC hard disk serial number, and then your registration code for an operation (and or or, or, or, with oneself to like), get the registration code, for validation, reverse calculation, if number is his hard drive, that is the machine, if not, the error, the second question did not contact, I'm sorry

CodePudding user response:

For SN partition processing, such as SN is 100 characters, 20 characters is hard disk serial number of the encrypted data, 20 characters is the MAC address of encrypted data, then 20 characters is to use the start time, end time of encrypted data, then the other characters is hard disk serial number and MAC address of encryption,,,,

Then, whatever you do,

But don't spend and waste your limited life infinite encryption to decrypt,
No matter how complex your algorithm under the debugger is useless, not to mention you are using VB,
