一、概念

Navicat中导出的带密码的文件后缀是.ncx结尾的，里面是xml格式的文件，存储了数据库的连接，方便在Navicat中进行导入和导出，共享数据库连接信息。

二、导出文件

1、创建的数据库连接信息

其中密码为：shiyrecYkXAJ65W5

2、导出带密码的连接信息

3、查看导出后的文件

打开导出以后的配置文件信息49.232.214.247.ncx

<?xml version="1.0" encoding="UTF-8"?>
<Connections Ver="1.5"><Connection ConnectionName="49.232.214.247_1" ProjectUUID="" ConnType="MYSQL" ServiceProvider="Default" Host="49.232.214.247" Port="3306" UserName="test_navicat" Password="35DFCD64284E35882562A71D5CAED5AAEFB0C5C7133922605A0DF5A3F1EE6419" SavePassword="true" SettingsSavePath="/Users/lydms/Library/Containers/com.navicat.NavicatPremium/Data/Library/Application Support/PremiumSoft CyberTech/Navicat CC/Common/Settings/0/0/MySQL/49.232.214.247" SessionLimit="0" ClientDriverVersion="Default" ClientCharacterSet="" ClientEncoding="65001" Keepalive="false" KeepaliveInterval="240" UseConnectionTimeout="true" ConnectionTimeoutSeconds="30" UseReadTimeout="false" ReadTimeoutSeconds="30" UseWriteTimeout="true" WriteTimeoutSeconds="30" Encoding="65001" MySQLCharacterSet="true" Compression="false" AutoConnect="false" NamedPipe="false" NamedPipeSocket="" UseAdvanced="false" SSL="false" SSH="false" HTTP="false" Compatibility="false"/>
</Connections>

三、Python代码解析

import binascii
import xml.etree.ElementTree as ETfrom cryptography.hazmat.backends import default_backend
from cryptography.hazmat.primitives import padding
from cryptography.hazmat.primitives.ciphers import Cipher, algorithms, modesaes_key = b'libcckeylibcckey'
aes_iv = b'libcciv libcciv '# 解密
def decrypt(upper_string):backend = default_backend()cipher = Cipher(algorithms.AES(aes_key), modes.CBC(aes_iv), backend=backend)decryptor = cipher.decryptor()encrypted_data = binascii.unhexlify(upper_string.lower())decrypted_padded_data = decryptor.update(encrypted_data) + decryptor.finalize()unpadder = padding.PKCS7(algorithms.AES.block_size).unpadder()try:data = unpadder.update(decrypted_padded_data) + unpadder.finalize()except ValueError as e:print("Decryption error: Invalid padding bytes.")raise ereturn data.decode()if __name__ == '__main__':# 本地文件地址xml_path_x = r'/Users/lydms/Downloads/49.232.214.247.ncx'# 格式化xml数据tree = ET.parse(xml_path_x)# 获取数据root_element = tree.getroot()for child in root_element:print('---------------------------------')print('ConnectionName:', child.attrib['ConnectionName'])print('Host:', child.attrib['Host'])print('Port:', child.attrib['Port'])print('UserName:', child.attrib['UserName'])print('source_Password:', child.attrib['Password'])print('Password:', decrypt(child.attrib['Password']))

可以看到将文件中加密后的密码，已经解析为明文秘钥了

加密后：35DFCD64284E35882562A71D5CAED5AAEFB0C5C7133922605A0DF5A3F1EE6419
明文：shiyrecYkXAJ65W5

执行结果：
