Using Project¶
Project is a folder include its own capsule and configuration file, which used to manage obfuscated scripts.
There are several advantages to manage obfuscated scripts by Project:
- Increment build, only updated scripts are obfuscated since last build
- Filter obfuscated scripts in the project, exclude some scripts
- More convenient to manage obfuscated scripts
Managing Obfuscated Scripts With Project¶
Use command init
to create a project:
pyarmor init --src=examples/pybench --entry=pybench.py projects/pybench
The project path projects/pybench will be created, and ther are 3 files in it:
.pyarmor_config
.pyarmor_capsule.zip
pyarmor.bat or pyarmor
.pyarmor_config
is project configuration of JSON format.
.pyarmor_capsule.zip
called Projct Capsule
, is used to
obfuscate scripts in this project and generate new license file for
those obfuscated scripts.
The last file is shell script to call pyarmor
in this project.
The common usage for project is to do any thing in the project path:
cd projects/pybench
Show project information:
./pyarmor info
Obfuscate all the scripts in this project:
./pyarmor build
Exclude the dist
, test
, the .py files in these
folder will not be obfuscated:
./pyarmor config --manifest "include *.py, prune dist, prune test"
Force rebuild:
./pyarmor build --force
Run obfuscated script:
cd dist
python pybench.py
After some scripts changed, just run build
again:
cd projects/pybench
./pyarmor build
Project Configuration File¶
Each project has a configure file. It’s a json file named
.pyarmor_config
stored in the project path.
name
Project name.
title
Project title.
src
Base path to match files by manifest template string.
Generally it’s absolute path.
manifest
A string specifies files to be obfuscated, same as MANIFEST.in of Python Distutils, default value is:
global-include *.py
It means all files anywhere in the src tree matching.
Multi manifest template commands are spearated by comma, for example:
global-include *.py, exclude __mainfest__.py, prune test
Refer to https://docs.python.org/2/distutils/sourcedist.html#commands
is_package
Available values: 0, 1, None
When it’s set to 1, the basename of src will be appended to output as the final path to save obfuscated scripts, and runtime files are still in the path output
When init a project and no –type specified, it will be set to 1 if there is __init__.py in the path src, otherwise it’s None.
disable_restrict_mode
Available values: 0, 1, None
When it’s None or 0, obfuscated scripts can not be imported from outer scripts. It’s more quickly.
When it’s set to 1, it the obfuscated scripts are allowed to be imported by outer scripts. It’s more security.
By default it’s set to 1.
Refer to Restrict Mode
entry
A string includes one or many entry scripts.
When build project, insert the following bootstrap code for each entry:
from pytransform import pyarmor_runtime pyarmor_runtime()
The entry name is relative to src, or filename with absolute path.
Multi entries are separated by comma, for example:
main.py, another/main.py, /usr/local/myapp/main.py
Note that entry may be NOT obfuscated, if manifest does not specify this entry. In this case, bootstrap code will be inserted into the header of entry script either. So that it can import other obfuscated modules.
output
A path used to save output of build. It’s relative to project path.
capsule
Filename of project capsule. It’s relative to project path if it’s not absolute path.
obf_module_mode
How to obfuscate whole code object of module:
- none
No obfuscate
- des
Obfuscate whole code object by DES algorithm
The default value is des
obf_code_mode
How to obfuscate byte code of each code object:
- none
No obfuscate
- des
Obfuscate byte-code by DES algorithm
- fast
Obfuscate byte-code by a simple algorithm, it’s faster than DES
- wrap
The wrap code is different from des and fast. In this mode, when code object start to execute, byte-code is restored. As soon as code object completed execution, byte-code will be obfuscated again.
The default value is wrap.
runtime_path
None or any path.
When run obfuscated scripts, where to find dynamic library _pytransform. The default value is None, it means it’s in the same path of
pytransform.py
.It’s useful when obfuscated scripts are packed into a zip file, for example, use py2exe to package obfuscated scripts. Set runtime_path to an empty string, and copy Runtime Files to same path of zip file, will solve this problem.
