【密文特征分析】加密类型判断

1、代码

import re
import sys

import requests


def post_url(data):
    """
    其实就是把「https://www.dcode.fr/cipher-identifier」网站的功能，改成接口形式
    之所以改成接口，是因为网站加载有些慢，很多不必要加载很是浪费时间
    :param data: 需要判断的密码字符串
    :return: 网站的返回分析数据
    """
    session = requests.session()

    # 获取 Cookie
    url = "https://www.dcode.fr/cipher-identifier"
    response = session.get(url)
    cookie = response.headers['Set-Cookie'].split(";")[0]

    # 带 Cookie 请求 api 接口
    url = "https://www.dcode.fr/api/"
    payload = f"tool=cipher-identifier&ciphertext={data}&clues="
    headers = {
        'Cookie': cookie,
        'Sec-Ch-Ua': '"Microsoft Edge";v="119", "Chromium";v="119", "Not?A_Brand";v="24"',

    }
    response = session.post(url, headers=headers, data=payload).json()
    return response["results"]


def clear_dict(cipher):
    """ 清理掉HTML标签 """
    new_dict = {}
    for key in cipher:
        new_dict[re.search('(.*?)', key).group(1)] = cipher[key]
    return new_dict


def format_dict(dictionary):
    """ 字典输出格式化 """
    max_key_len = max(len(key) for key in dictionary.keys())
    max_value_len = max(len(value) for value in dictionary.values())

    for key, value in dictionary.items():
        key_spaces = ' ' * (max_key_len - len(key))
        value_spaces = ' ' * (max_value_len - len(value))
        print(key + key_spaces + ' : ' + value + value_spaces)


if __name__ == '__main__':
    if len(sys.argv) == 2:
        cipher_dict = post_url(sys.argv[1])
    else:
        print("使用说明 : python3 cipher_identifier.py {密文}")
        exit(1)
    format_dict(clear_dict(cipher_dict))

2、使用说明

没有什么好说明的，就是 https://www.dcode.fr/cipher-identifier 网站接口，网站加载太慢了，所以我就把接口做成了Python脚本，方便使用，节省时间。
