And step S104, receiving the encrypted script file fed back by the encryption and decryption issuing system. In practical application, after the encryption and decryption issuing system processes the original script file to obtain the encrypted script file, the encrypted script file is sent to a server side so as to carry out subsequent operation.
And step S106, if a script file request sent by the client is received, feeding back the encrypted script file to the client so that the client updates the script by using the encrypted script file.
