Abstract

The invention provides a method and device for packaging scripts in an NPK mode and running script files in an NPK format, and relates to the technical field of data processing. According to the method for packaging the scripts in the NPK mode, encryption operation is conducted on decryption scripts so that the encrypted decryption scripts are obtained, encryption operation is performed on the to-be-encrypted target script by adopting the encryption script to obtain an encrypted target script, the encrypted decryption script and the encrypted target script are packaged to generate a target NPKpacket, when the target NPK packet is sent to the client, the target script is encrypted, and the decrypted script is also encrypted, so that the decrypted script does not exist in the target NPK packet in a plaintext mode any more, the risk that the target script is leaked or even tampered can be reduced through two encryption operations, and the security of the target script is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and device for packaging scripts in NPK mode and running script files in NPK format. Background technique [0002] As an object-oriented and dynamically typed language, Python is widely used in many fields such as artificial intelligence and software development because of its scalability, embeddability, and portability. Take the application in the game development process as an example. In game development, in order to protect the game script from being decompiled, it is often necessary to encrypt and package the game script. [0003] Among the existing encrypted packaging methods, the NPK format is a software installation package format developed by NetDragon. As a typical encrypted packaging method, it is mainly based on bytecode obfuscation of Python scripts. The Python script is encrypted once. [0004] However, in the existing solution, since th...
