Instance 470 use the serial number of the NIC to design the software registration program
Instance descriptionIn this example, the software registration code is generated using the serial number of the local Nic. Run the program to automatically obtain the serial number of the local Nic. Click Generate registration code to generate the software registration code.
In order to make the developed software more widely used, developers hope that more users can try the software. On the other hand, they do not want users to use unauthorized software for free for a long time, this requires the design of software registration procedures. The following describes how to protect
2009-2012 I had to use a broadband client plug-in to access the Internet at school. In the past 11 years, I had to dial up and chat on the LAN...
Through my analysis, after you dial-up Internet access, this broadband client plug-in will change the ARP cache table of the WindowsXP system and define it as a place where the MAC address is 00-00-00-00-00-66, in this way, when an IP address in the lan sends an ARP packet, the physical MAC address of the IP address in the ARP cache table on your comp

How to encrypt software
Generally, software in the C/S architecture is divided into two parts: client and server.
The software installed on the client machine is generally only a client. Therefore, we only need to add a validation table on the server side and a serial number field in the table.
When the client is installed for the first time, determine whether
1. Create a key
1. Create a key
Step 1:
Step 2: Next Step
Step 3: enter the name and email address
Step 4: Enter passphrase
Step 5: Follow the software prompts to continue the next step until completion ~~~~
Now you can see the key you just created in the software ~~~~~~
2. Export the key
1) Right-click the created key
2) Select the Save path. Here, the desktop I selected should contain Private Keys.
