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:///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:]))

加密后在字符串前面添加了一个v10，因此解密前要先去掉

总结
