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
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'');
我想编写一个python脚本来解密cookie。我已经看到 Chrome 33 Beta的Cookie问题,但依赖于 CryptUnprotectData
这是一个Windows API。
首先我想知道如何加密Cookie。我已经阅读过3DES和AES,但是我没有找到一个可靠的来源来获取信息。
我将编写代码进行必要的加密和解密,如果我有关如何做的信息。
谢谢
我已经发布了一个示例Python脚本此处,以解码OSX或Linux中的加密Cookie。
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 '');
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.
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.
I will write the code to do the necessary encryption and decryption if I have info about how to do it.
Thank you
I've posted an example Python script here for decoding the encrypted cookies in either OSX or Linux.
