Python and Pyinstaller: include binary application in code

Question

I have a small app. For protection I use c:/hwid.exe. The application returns HWID of pc. example code:

def HWID_LIC():
    try:
        if hashlib.md5(open('c:\hwid.exe', 'rb').read()).hexdigest() != 'bca173dc':
            sys.exit(1)
        out = os.popen("c:\hwid.exe").read().strip()
        if out not in lic:
            sys.exit(1)
    except:
        sys.exit(1)

HWID_LIC()

I want to include hwid.exe in my application and need the solution all in one file. Is possible to do this in Python? hwid.exe has 30 kb.

This is possible. You need to search your hwid.exe in sys._MEIPASS

import sys
import os
import hashlib

def HWID_LIC():
    if os.path.isfile('hwid.exe'):
        print('file found in .')
    else:
        print('file not found in .')

    if os.path.isfile(sys._MEIPASS + os.sep + 'hwid.exe'):
        print('file found in sys._MEIPASS')
    else:
        print('file not found')
    print(hashlib.md5(open(sys._MEIPASS + os.sep + 'hwid.exe', 'rb').read()).hexdigest())


if __name__ == '__main__':
    HWID_LIC()

Example spec file:

# -*- mode: python -*-
a = Analysis(['test.py'],
             pathex=[],
             hiddenimports=[],
             runtime_hooks=None)
import platform
if platform.system().find("Windows")>= 0:
    a.datas = [i for i in a.datas if i[0].find('Include') < 0]
a.binaries = [x for x in a.binaries if not x[0].startswith("scipy")]
a.binaries = [x for x in a.binaries if not x[0].startswith("numpy")]
a.datas += [('hwid.exe','.\\hwid.exe','DATA'),]
pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          name='test.exe',
          debug=False,
          strip=None,
          clean=True,
          upx=False,
          console=True)

and create the onefile exe whith

pyinstaller t_onefile.spec

When executing test.exe you see:

j:\tmp>test.exe
file not found in .
file found in sys._MEIPASS
