  2. Do not call the system time to see if the trial period has passed. You can call the creation time of some system files.
  3. Do not write sensitive information in plain text in the program to prevent direct hexadecimal viewing.
  4. The encryption or verification part is highly coupled with the software entity part (though inconvenient to maintain)
  5. Do not compare the registration code in plain text, anti-memory patch, at least MD5 comparison
