Description
Technical Field
The invention belongs to the technical field of network security, and particularly relates to a Python source code protection method and system based on pyc encryption.
Background
The Python programming language can be said to be the most popular computer programming language at present, and from the birth of the Python language in the early 90 s of the 20 th century to the present, more and more people begin to use the Python, and the shadow of the Python can be seen in various fields. Python belongs to the scripting (interpretive) language, namely written Python code is finally interpreted and executed by a Python interpreter, a Python code file (. py) of the Python code is basically not different from a text file, and any text editor can be opened. In some business scenarios, it is not desirable to expose the source code, so some technical means need to be used to secure the Python source code.
The currently commonly used Python source code protection schemes are probably as follows:
1. python source code obfuscation: the protection purpose is realized by renaming variable names, class names, function names and the like in the Python source code to be meaningless names or inserting meaningless junk codes into the source code, but the protection of the source code is not realized essentially, and the renaming meaningless variable names, class names, function names and the like can be renamed back to be meaningless names by some methods.
2. Using the packaging tool (py2exe, pyinstaller) packs directly into. exe's executable: the. py file is packaged into the. exe executable file for protection purposes using a third party packaging tool. However, these packaging tools are usually open source, and the packaging process can be known by analyzing the source code, and the packaging process can be unpacked according to the reverse process.
3. Convert py file to so file: the protection is achieved by converting the py file into a dynamically linked library so file, but this method is not suitable for large projects and the conversion process is cumbersome.
However, the above existing Python source code protection schemes all have some non-negligible drawbacks: firstly, for the first method, the renamed meaningless variable names, class names, function names and the like can be changed into meaningful names in a secondary renaming mode, and then the Python source codes are obtained, so that the method has low protection on the source codes; secondly, for the second method, the source code can be analyzed to understand the packing process, and the packing process is unpacked according to the reverse process to obtain the Python source code, so that the method has low protection on the source code; third, the conversion process of the third method is complicated and is not suitable for large projects.

specifically, in the step, a complex function in a py _ complex module is used for performing byte code conversion processing on a user-defined Python file imported by a user to generate a corresponding pyc file;
the step (1) has the advantage that the original self-defined Python file is deleted, so that the safety of the source code file is ensured.
(2) Encrypting the pyc file obtained in the step (1) to obtain an encrypted pyc file;

specifically, the Encryption algorithm used in this step is a symmetric Encryption algorithm, preferably an Advanced Encryption Standard (AES) Encryption algorithm;
(2-2) setting a self-defined encrypted file mark for the pyc ciphertext obtained in the step (2-1) to obtain a new pyc ciphertext;
specifically, in the step, the last two bytes of the Magic number (Magic number) in the pyc ciphertext obtained in the step (2-1) are modified into 'little', so that a user-defined encrypted file mark is set for the pyc ciphertext;
further, the pyc ciphertext contains three pieces of information: magic numbers for Python, time information for pyc file creation, and PyCodeObject object.
(2-3) outputting the new pyc ciphertext obtained in the step (2-2) to a specified path to obtain a final encrypted pyc file;
for example, the new pyc ciphertext from step (2-2) may be exported to a path such as "C: \ Users \ Desktop \ import.
