pyinstaller: problem when using --key command

Question

I'm trying to use pyinstaller -F --key="123456" my.py to encrypt exe, but got this error instead:

And here is the content of my.py, no extra files or datas needed:

import requests
from bs4 import BeautifulSoup


def get_page_source(page_num):
    print('Crawling page %d' % page_num)

    url = 'http://books.toscrape.com/catalogue/page-%d.html' % page_num
    r = requests.get(url)
    return r.text


def get_book_info(page_source):
    soup = BeautifulSoup(page_source, features='lxml')
    titles = soup.select('h3 > a')
    for title in titles:
        print(title.get('title'))


if __name__ == '__main__':
    # 1-50
    for i in range(1, 51):
        page_source = get_page_source(i)
        get_book_info(page_source)

Don't have any clue on how to solve it. It works fine when I stop using --key command.

PyInstaller==3.4 Python==3.6

Answer 1

It is known bug and it is because Pyinstaller encryption is not compatible with pycryptodome . So you need to install the old PyCrypto to make it work.

There is a good answer in here for installing the old PyCrypto .

pip install pycrypto

Answer 2

install: pip install cryptography to solve the problem & for the lates encryption ver of pycrypto. PyCrypto 2.x is unmaintained, obsolete, and contains security vulnerabilities. know more at PyCrypto
