#!/usr/bin/env python3import reimport sysimport datetimeimport subprocessfrom Crypto.Cipher import AESfrom binascii import a2b_hexclass check_license_file(): def license_check(self): license_dic = self.parse_license_file() sign = self.decrypt(license_dic['Sign']) sign_list = sign.split('#') mac = sign_list[0].strip() date = sign_list[1].strip() if (mac != license_dic['MAC']) or (date != license_dic['Date']): print('*Error*: License file is modified!') sys.exit(1) # Check MAC and effective date invalid or not. if len(sign_list) == 2: mac = self.get_mac() current_date = datetime.datetime.now().strftime('%Y%m%d') if sign_list[0] != mac: print('*Error*: Invalid host!') sys.exit(1) # Current time must be before effective date. if sign_list[1] < current_date: print('*Error*: License is expired!') sys.exit(1) else: print('*Error*: Wrong Sign setting on license file.') sys.exit(1) def parse_license_file(self): license_dic = {} license_file = 'License.dat' with open(license_file, 'r') as LF: for line in LF.readlines(): if re.match('^s*(S+)s*:s*(S+)s*$', line): my_match = re.match('^s*(S+)s*:s*(S+)s*$', line) license_dic[my_match.group(1)] = my_match.group(2) return (license_dic) def decrypt(self, content): aes = AES.new(b'2021052020210520', AES.MODE_CBC, b'2021052020210520') decrypted_content = aes.decrypt(a2b_hex(content.encode('utf-8'))) return (decrypted_content.decode('utf-8')) def get_mac(self): mac = '' SP = subprocess.含糊的绿草sbin/ifconfig', shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE) (stdout, stderr) = SP.communicate() for line in str(stdout, 'utf-8').split('n'): if re.match('^s*ethers+(S+)s+.*$', line): my_match = re.match('^s*ethers+(S+)s+.*$', line) mac = my_match.group(1) break return macif __name__ == '__main__': # check license file check_license_file().license_check() 3.把解析脚本转换成.so文件setup.py,
# -*- coding: UTF-8 -*-from distutils.core import setupfrom Cython.Build import cythonizepy_files = ['check_license_file.py', ]setup(ext_modules=cythonize(py_files), )执行脚本python setup.py build_ext --inplace生成文件，把其中的.so文件该名成check_license_file.so
4. 使用licensetest.py
from utils.license.check_license_file import check_license_file
check_license_file().license_check()
a = input(‘请输入数字：’)
print(a)
