determining that the predetermined hardware lock is connected to the computing device when the hardware identification number of the connected hardware lock and the hardware identification number stored in the encryption file are the same; and

determining that the predetermined hardware lock is not connected to the computing device when the hardware identification number of the connected hardware lock and the hardware identification number stored in the encryption file are not the same.

8. The storage medium as claimed in claim 5 , wherein the searching step comprises:

traversing all decryption rules stored in the computing device to search a decryption rule with a same software identification code of the PHP software program;

using the decryption rule with the same software identification code of the PHP software program to decrypt the encrypted file when the decryption rule with the same software identification code of the PHP software program is searched; and

displaying a prompt that indicates the decryption rule corresponding to the encryption rule does not exist when the decryption rule with the same software identification code of the PHP software program is not searched.

9. A computing device, comprising:

at least one processor; and

a storage system that stores one or more programs, when executed by the at least one processor, cause the at least one processor to:

encrypt a hypertext preprocessor (PHP) software program of the computing device using an encryption rule to obtain an encrypted file;

generate a decryption rule corresponding to the encryption rule to decrypt the encrypted file;

store the decryption rule corresponding to the encryption rule to the storage system;
