在Python中解密Chrome Linux BLOB加密的Cookie [英] Decrypt Chrome Linux BLOB encrypted cookies in Python

问题描述

我在Ubuntu中有Chrome 33以上的版本，我发现这些Cookie是以BLOB结构加密的：

I have Chrome 33+ in Ubuntu and I see that the cookies are encrypted in a BLOB structure:

CREATE TABLE cookies（creation_utc INTEGER NOT NULL UNIQUE PRIMARY KEY，host_key TEXT NOT NULL，name TEXT NOT NULL，value TEXT NOT NULL，path TEXT NOT NULL，expires_utc INTEGER NOT NULL，secure INTEGER NOT NULL，httponly INTEGER NOT NULL，last_access_utc INTEGER NOT NULL，has_expires INTEGER NOT NULL DEFAULT 1，persistent INTEGER NOT NULL DEFAULT 1，priority INTEGER NOT NULL DEFAULT 1，encrypted_value BLOB DEFAULT''）;


我想写一个python脚本来解密cookie。我看到有 Chrome问题Chrome 33测试版，但依赖于 CryptUnprotectData 表示它是Windows API。

I would like to write a python script to decrypt the cookie. I've seen that there is Cookie issue with Chrome 33 Beta but relies in CryptUnprotectData that it's a Windows API.

首先我想知道cookies是如何加密的。我已经阅读3DES和AES，但我找不到一个可靠的来源获取信息。

First of all I would like to know how are the cookies encrypted. I've read 3DES and AES but I don't find a trusty source to get the info.

我将编写代码做必要的加密和解密，如果我

I will write the code to do the necessary encryption and decryption if I have info about how to do it.

谢谢

推荐答案

我已发布示例Python脚本此处解码OSX或Linux中的加密Cookie。

I've posted an example Python script here for decoding the encrypted cookies in either OSX or Linux.
