Python algorithm encryption

Encrypted Code Snippet Sample

File name: iter_n.py

import time

def iter_from_n(n):
    list_n = []
    for index,value in enumerate(range(n)):
        list_n.append([index,value])
    return list_n
    
if __name__=="__main__":
    t1 = time.time()
    iter_from_n(100000)
    t2 = time.time()
    print ("花费时间:{}".format(t2-t1))

0. Execute the py file directly

Command: python iter_n.py

1.pyc encryption

Command: python -m compileall [directory|file.py]

Command: python iter_n.cpython-37.pyc

Description: Cannot directly call the internal package module

2.pyd encryption

2.1 Cython encryption

pip install Cython==0.29.22
gcc related environment to compile related files

setup.py file

from distutils.core import setup
from Cython.Build import cythonize

setup(name='iter_n',
     ext_modules=cythonize('iter_n.py'))

2.1.1 Compile command

python setup.py build_ext --inplace

2.1.2 Compile command

python setup.py [build|build_ext]
python setup.py install

2.2 easycython encryption

pip install easycython

print (iter_from_n(10))

3.py2exe

pip install py2exe
setup.py file

#coding=utf-8
from distutils.core import setup
import py2exe

options = {"py2exe":
  {
    "compressed": 1, #压缩
    "optimize": 2,
    "ascii": 1,
    "bundle_files": 1 #所有文件打包成一个exe文件
  }
}


setup (
  options = options,
  zipfile=None,  #不生成library.zip文件
  console=[{"script": "iter_n .py", 'icon_resources': [(1, 'icon.ico')]  }]#源文件，程序图标
)

3.1 Compile command

python setup.py py2exe

4.pyinstaller
