Due to the confidentiality needs of the project , The developed projects need to be encrypted , This paper gives two methods .
encryption py Code , Although compiled as pyc Not much ( It is easy to decompile the source code ), But it still has some encryption effect , If the project is tight , This method can be used for emergency treatment .
python -m compileall -f -q -b "py Folder "
This command will send py Files will generate corresponding pyc file
Then execute the following command , Delete the py file , Only keep pyc file
find . -name "*.py" -type f -print -exec rm -rf {
} \;Finally, execute the run pyc Just file it
Such as ： python ****.pyc
Be careful ： This method encrypts and uses python The version should be consistent , Otherwise, an error will be reported . I.e. operation python -m compileall -f -q -b "py Folder " And python ****.pyc The version should be consistent .
pip3 install Cython sudo apt-get update sudo apt-get install python-devel sudo apt-get install gcc
Fill in the following ：
#-* -coding: UTF-8 -* -
"""
The premise of execution ：
System installation python-devel and gcc
Python install cython
Compile a folder ：
python py2so.py BigoModel
Generate results ：
Catalog build Next
After the build is complete ：
The startup file also needs py/pyc Take on , Must be activated py/pyc Copy to the compilation directory and delete so file

At the end of the run , project_dir_path Will generate a build Folder , Put the .os All files are moved to the corresponding location of the encrypted folder , Delete py file , If it is a startup file , It is suggested to keep , You can run the program through the startup file .
take py File compiled into pyc：
Python A standard library is provided with the name compileall The library of , It's easy to compile . Easy and convenient , Raised a little source code crack threshold
Good platform compatibility , py Where can I run , pyc Where to run . But there are ready-made decompilers （ python-uncompyle6 ）, The cost of cracking is low . It is suggested that the project time is tight , Use in case of emergency .
take py Turn it into so file ：
Cython Method encryption is to encrypt py The file to so file , use so File replacement py file , The execution rate will be faster than python faster , But sometimes I encounter some code that doesn't work well , Only test against , The invalid ones will not be encrypted or encrypted in other ways . Good encryption effect , Not easy to decompile , But the project needs to be tested step by step .
