For another example, the lower the weight or level information of the sender, the lower the security and the lower the reliability, so that a class file generator with complicated corresponding encryption performance can be provided to ensure the security of the encrypted information on the sender. Similarly, the class file generator with simple encryption performance or the class file generator with complex encryption performance is selected, and the type of the encryption information or the type of the encryption information and the sender information can be used as the selection condition.
