Python代码混淆、加密方法
1. 安装:
pip install pyminifier
或
pip install pyminifier -i https://pypi.tuna.tsinghua.edu.cn/simple/ --trusted-host pypi.tuna.tsinghua.edu.cn
如果报错,则通过以下方法解决
pip install pywin32
pip install wheel
pip install pyminifier
2. 代码加密
pyminifier --nonlatin --replacement-length=10 -O xxx.py 注:(10和大写ou)
或
pyminifier --obfuscate your_script.py > obfuscated_script.py
该方法比较普通,加密效果弱

3. 另一种方法, 利用Base64对代码进行再次编码,再利用lzma算法进行压缩,但是这种加密方式仅仅用于代码没有调用隐式导入的情况。 (UnicodeDecodeError解决链接)
pyminifier --lzma "xxx.py"

4. 两种方法混合使用,效果最佳
5. 语法介绍
replacement-length 代码的变量的一个混淆长度, int
-O :混淆所有函数/方法名、变量和类。默认是不要混淆。
6. 操作示例:
# 将脚本 demo02.py 按 lzma 加密,并生成新的脚本 demo02_2.py
C:\Users\54867>pyminifier --lzma "demo02.py">demo02_2.py
# 将脚本 demo02.py 加密,并生成新的脚本 new_demo02.py
C:\Users\54867>pyminifier -O --replacement-length=10 ./demo02.py>new_demo02.py
#在 cmd 中执行这个脚本,查看是否正常运行
C:\Users\54867>python new_demo02.py
# 加密后生成新脚本,并自定义路径(已有路径)
C:\Users\54867>pyminifier -O --replacement-length=10 ./demo02.py>D:\输出\new_demo02.py
7. pyminifier 详细命令方法如下:
pyminifier -h
Usage: pyminifier [options] "<input file>"
Options:
--version show program's version number and exit
-h, --help show this help message and exit
-o <file path>, --outfile=<file path>
Save output to the given file.
-d <file path>, --destdir=<file path>
Save output to the given directory. This option is
required when handling multiple files. Defaults to
'./minified' and will be created if not present.
将输出保存到给定的目录。当处理多个文件时,此选项是必需的。默认为'./minified',如果不存在,将被创建。
--nominify Don't bother minifying (only used with --pyz).
--use-tabs Use tabs for indentation instead of spaces.
使用制表符代替空格来缩进。
--bzip2 bzip2-compress the result into a self-executing python
script. Only works on stand-alone scripts without
implicit imports.
以bzip2方式压缩将结果到一个自动执行的python脚本中。只能在独立脚本上工作,不需要隐式导入。
--gzip gzip-compress the result into a self-executing python
script. Only works on stand-alone scripts without
implicit imports.
以gzip方式压缩结果到一个自执行的python脚本中。只能在独立脚本上工作,不需要隐式导入。
--lzma lzma-compress the result into a self-executing python
script. Only works on stand-alone scripts without
implicit imports.
以lzma方式压缩将结果到一个自动执行的python脚本中。只能在独立脚本上工作,不需要隐式导入。
--pyz=<name of archive>.pyz
zip-compress the result into a self-executing python
script. This will create a new file that includes any
necessary implicit (local to the script) modules.
Will include/process all files given as arguments to
pyminifier.py on the command line.
-O, --obfuscate Obfuscate all function/method names, variables, and
classes. Default is to NOT obfuscate.
--obfuscate-classes Obfuscate class names.
--obfuscate-functions
Obfuscate function and method names.
--obfuscate-variables
Obfuscate variable names.
--obfuscate-import-methods
Obfuscate globally-imported mouled methods (e.g.
'Ag=re.compile').
--obfuscate-builtins Obfuscate built-ins (i.e. True, False, object,
Exception, etc).
--replacement-length=1
The length of the random names that will be used when
obfuscating identifiers.
--nonlatin Use non-latin (unicode) characters in obfuscation
(Python 3 only). WARNING: This results in some
SERIOUSLY hard-to-read code.
--prepend=<file path>
Prepend the text in this file to the top of our
output. e.g. A copyright notice.
