Protect your python script, encrypt .pyc to .pye and decrypt when import it

0.9.x Beta

• your_script.py import pyconcrete
• pyconcrete will hook import module
• when your script do import MODULE, pyconcrete import hook will try to find MODULE.pye first and then decrypt MODULE.pye via _pyconcrete.pyd and execute decrypted data (as .pyc content)
• encrypt & decrypt secret key record in _pyconcrete.pyd (like DLL or SO) the secret key would be hide in binary code, can't see it directly in HEX view

• only support AES 128 bit now
• encrypt & decrypt by library OpenAES

• get the pyconcrete source code

$ git clone <pyconcrete repo> <pyconcre dir>

• install pyconcrete

$ python setup.py install

• need to input your passphrase create secret key for encrypt python script.

• same passphrase will generate the same secret key

• convert your script to *.pye

$ pyconcrete-admin.py compile_pye --file=<your py script>
$ pyconcrete-admin.py compile_all_pye --dir=<your py module dir>

• remove *.py or copy *.pye to other folder

• import pyconcrete in your main script

  • recommendation project layout

main.py  # import pyconcrete and your lib
src/*.pye  # your libs

• install pyconcrete as lib

$ python setup.py install \
  --install-lib=<your project path> \
  --install-scripts=<where you want to execute pyconcrete-admin.py>

• import pyconcrete in your main script
  • recommendation project layout

main.py       # import pyconcrete and your lib
pyconcrete/*  # put pyconcrete lib in root, keep it as original files
src/*.pye     # your libs
