想了解怎样使用Python提取Chrome浏览器保存的密码的相关内容吗,刘润森!在本文为您仔细讲解Python提取Chrome浏览器保存的密码的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Python提取Chrome浏览器保存的密码,Python提取浏览器密码,下面大家一起来学习吧。

由于Chrome会将大量浏览数据本地保存磁盘中,在本教程中,我们将编写 Python 代码来提取 Windows 计算机上 Chrome 中保存的密码。

首先,让我们安装所需的库:

pip install pycryptodome pypiwin32

打开一个新的 Python 文件,并导入必要的模块:

import os
import json
import base64
import sqlite3
import win32crypt
from Crypto.Cipher import AES
import shutil
from datetime import timezone, datetime, timedelta

在直接进入提取 chrome密码之前,我们需要定义一些有用的函数来帮助我们在主函数中。

def get_chrome_datetime(chromedate):
    """从chrome格式的datetime返回一个`datetime.datetime`对象
因为'chromedate'的格式是1601年1月以来的微秒数"""
    return datetime(1601, 1, 1) + timedelta(microseconds=chromedate)

def get_encryption_key():
    local_state_path = os.path.join(os.environ["USERPROFILE"],"AppData", "Local", "Google", "Chrome","User Data", "Local State")
    with open(local_state_path, "r", encoding="utf-8") as f:
        local_state = f.read()
        local_state = json.loads(local_state)

    # 从Base64解码加密密钥
    key = base64.b64decode(local_state["os_crypt"]["encrypted_key"])
    # 删除 DPAPI str
    key = key[5:]
    # 返回最初加密的解密密钥
    # 使用从当前用户的登录凭据派生的会话密钥
    # 官方文档doc: http://timgolden.me.uk/pywin32-docs/win32crypt.html
    return win32crypt.CryptUnprotectData(key, None, None, None, 0)[1]


def decrypt_password(password, key):
    try:
        # 获取初始化向量
        iv = password[3:15]
        password = password[15:]
        # 生成密码
        cipher = AES.new(key, AES.MODE_GCM, iv)
        # 解密密码
        return cipher.decrypt(password)[:-16].decode()
    except:
        try:
            return str(win32crypt.CryptUnprotectData(password, None, None, None, 0)[1])
        except:
            # not supported
            return ""

下面是main主要功能:

def main():
    # 获取AES密钥
    key = get_encryption_key()
    # 本地sqlite Chrome数据库路径
    db_path = os.path.join(os.environ["USERPROFILE"], "AppData", "Local","Google", "Chrome", "User Data", "default", "Login Data")
    # 将文件复制到其他位置
    # 因为如果chrome当前正在运行,数据库将被锁定
    filename = "ChromeData.db"
    shutil.copyfile(db_path, filename)
    # 连接数据库
    db = sqlite3.connect(filename)
    cursor = db.cursor()
    # 登录表中有我们需要的数据
    cursor.execute("select origin_url, action_url, username_value, password_value, date_created, date_last_used from logins order by date_created")
    # iterate over all rows
    for row in cursor.fetchall():
        origin_url = row[0]
        action_url = row[1]
        username = row[2]
        password = decrypt_password(row[3], key)
        date_created = row[4]
        date_last_used = row[5]        
        if username or password:
            print(f"Origin URL: {origin_url}")
            print(f"Action URL: {action_url}")
            print(f"Username: {username}")
            print(f"Password: {password}")
        else:
            continue
        if date_created != 86400000000 and date_created:
            print(f"Creation date: {str(get_chrome_datetime(date_created))}")
        if date_last_used != 86400000000 and date_last_used:
            print(f"Last Used: {str(get_chrome_datetime(date_last_used))}")
        print("="*50)
    cursor.close()
    db.close()
    try:
        # 尝试删除复制的db文件
        os.remove(filename)
    except:
        pass

首先,我们使用之前定义的get_encryption_key()函数获取加密密钥,然后我们将 sqlite 数据库(位于"%USERPROFILE%\AppData\Local\Google\Chrome\User Data\default\Login Data"保存密码的位置)复制到当前目录并连接到它,这是因为原始数据库文件将被锁定Chrome 当前正在运行。

之后,我们对登录表进行选择查询并遍历所有登录行,我们还解密每个密码date_created并将date_last_used日期时间重新格式化为更易于阅读的格式。

最后,我们打印凭据并从当前目录中删除数据库副本。

让我们调用主函数,完美提取Chrome浏览器保存的密码:
