python与sqlite3实现解密chrome cookie实例代码_Python

本文研究的主要问题：有一个解密chrome cookie的事情，google出了代码，却不能正常执行，原因在于sqlite3的版本太低，虽然我切换到了python3.5的环境，但sqlite3的版本也只有3.6。

google了许久，终于找到方法：

1、进入页面 http://www6.atomicorp.com/channels/atomic/centos/6/x86_64/RPMS/

2、下载 atomic-sqlite-sqlite-3.8.5-2.el6.art.x86_64.rpm

3、 rpm -Uvh atomic-sqlite-sqlite-3.8.5-2.el6.art.x86_64.rpm

4、执行命令 sqlite3 -version 一切都ok啦

顺便附上解析cookie的代码

									#coding=utf-8 

									import os 

									import sqlite3 

									#import keyring 

									from Crypto.Cipher import AES 

									from Crypto.Protocol.KDF import PBKDF2 

									#for mac 

									#my_pass = keyring.get_password('Chrome Safe Storage', 'Chrome') 

									#my_pass = my_pass.encode('utf8') 

									#iterations = 1003 

									#cookie_file = os.path.expanduser('~/Library/Application Support/Google/Chrome/Default/Cookies') 

									#for linux 

									my_pass = 'peanuts'.encode('utf8') 

									iterations = 1

									cookie_file = 'Cookies'

									salt = b'saltysalt'

									length = 16

									iv = b' ' * length 

									def expand_str(token): 

									  token_len = len(token) 

									  expand_len = (token_len // length + 1) * length - token_len 

									  return token.encode('ascii') + b'\x0c' * expand_len 

									def aes_encrypt(token): 

									  key = PBKDF2(my_pass, salt, length, iterations) 

									  cipher = AES.new(key, AES.MODE_CBC, IV=iv) 

									  enc_token = cipher.encrypt(token) 

									  return b'v10' + enc_token 

									def aes_decrypt(token): 

									  key = PBKDF2(my_pass, salt, length, iterations) 

									  cipher = AES.new(key, AES.MODE_CBC, IV=iv) 

									  dec_token = cipher.decrypt(token) 

									  return dec_token 

									def query_cookies(): 

									  with sqlite3.connect(cookie_file) as conn: 

									    sql = "select host_key, name, encrypted_value from cookies where name = 'jzysYonghu'"

									    #sql = "select * from cookies" 

									    result = conn.execute(sql).fetchall() 

									  return result 

									def write_cookies(enc_token): 

									  with sqlite3.connect(cookie_file) as conn: 

									    b = sqlite3.Binary(enc_token) 

									    sql = """update cookies set encrypted_value = ? where name = 'remember_token'"""

									    conn.execute(sql, (b, )) 

									def change_user(token): 

									  write_cookies(ase_encrypt(expand_str(token))) 

									if __name__ == '__main__': 

									  data = query_cookies()[0][2] 

									  print(data) 

									  print(len(data)) 

									  print(aes_decrypt(data[3:]))
