python、go、node的ja3指纹实现

一.初识

1.什么是ja3相信大家都有所耳闻，这里就不做太多概述，简单来讲就是就是基于tls/ssl协议的客户端指纹特征识别技术。

2.绕过ja3的四种方法

• 1.访问ip指定host绕过waf
• 2.代理中转请求(go版本有实现可以去了解下)
• 3.更换request工具库
• 4.魔改requests

3.tls检测网站

• akamai 1.75
• akamai2.0
• Cloudflare(5秒盾)

这里我们讲解各语言版本的实现，详细了解ja3的可以移步到一下文章。

二.语言实现——(案例猿人学19题)

• python

  一.pyhttpx

import pyhttpx
sess= pyhttpx.HttpSession()
url = f"https://match.yuanrenxue.com/api/match/19?page=1"
response = sess.get(url,headers=Headers)

二. Pycurl（pycurl是curl的一个python版本）

import pycurl, json
from io import BytesIO

Class getAll():
	def __init__(self):
		self.pyc=pycurl.Curl()
		self.buffer=BytesIO()
	
	def getoutPut():
		self.pyc.setopt(pycurl.URL, 'http://some-url')
		#跳过验证
		self.pyc.setopt(pycurl.SSL_VERIFYHOST,0)
		self.pyc.setopt(pycurl.SSL_VERIFYPEER,0)
		self.pyc.setopt(pycurl.POST,1)
		self.pyc.setopt(pycurl.WRITEDATA,self.buffer)
		self.pyc.setopt(pycurl.HTTPHEADER, ['content-type: 		   	     				application/json','content-type:multipart/form-data'])
		data = json.dumps({"name": "abc", "path": "def", "target": "ghi"})
		self.pyc.setopt(pycurl.POSTFIELDS, data)
		self.pyc.perform()
		self.pyc.close()
		print(self.buffer.getvalue().decode('utf-8'))

三.魔改open_ssl

from requests.adapters import HTTPAdapter
from requests.packages.urllib3.util.ssl_ import create_urllib3_context

ORIGIN_CIPHERS = ('ECDH AESGCM:DH AESGCM:ECDH AES256:DH AES256:ECDH AES128:DH AES:ECDH HIGH:'
'DH HIGH:ECDH 3DES:DH 3DES:RSA AESGCM:RSA AES:RSA HIGH:RSA 3DES')


class DESAdapter(HTTPAdapter):
    def __init__(self, *args, **kwargs):
        """
        A TransportAdapter that re-enables 3DES support in Requests.
        """
        CIPHERS = ORIGIN_CIPHERS.split(':')
        random.shuffle(CIPHERS)
        CIPHERS = ':'.join(CIPHERS)
        self.CIPHERS = CIPHERS   ':!aNULL:!eNULL:!MD5'
        super().__init__(*args, **kwargs)
        
        
    def init_poolmanager(self, *args, **kwargs):
        context = create_urllib3_context(ciphers=self.CIPHERS)
        kwargs['ssl_context'] = context
        return super(DESAdapter, self).init_poolmanager(*args, **kwargs)

    def proxy_manager_for(self, *args, **kwargs):
        context = create_urllib3_context(ciphers=self.CIPHERS)
        kwargs['ssl_context'] = context
        return super(DESAdapter, self).proxy_manager_for(*args, **kwargs)
        
import requests
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36 Edg/92.0.902.67'}
s = requests.Session()
s.headers.update(headers)
 
for _ in range(5):
    s.mount('https://ja3er.com', DESAdapter())
    resp = s.get('https://ja3er.com/json').json()
    print(resp)

提示：cycletls是一个针对go和node的ja3实现

项目地址:cycletls

• go（cycletls）

  1.安装：go get github.com/Danny-Dasilva/CycleTLS/cycletls

  2.使用

package main

import (
	"github.com/Danny-Dasilva/CycleTLS/cycletls"
	"log"
)

func main() {

	client := cycletls.Init()

	response, err := client.Do("https://match.yuanrenxue.com/api/match/19?page=1", cycletls.Options{
		Body:      "",
		Ja3:       "771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-		 49161-49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-		  21,29-23-24-25-256-257,0",
	    UserAgent: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) 			    	 Gecko/20100101 Firefox/87.0",
	}, "GET")
	if err != nil {
		log.Print("Request Failed: "   err.Error())
	}
	log.Println(response)
}

• node（cycletls）

  1.安装：npm install cycletls

  2.使用

const initCycleTLS = require('cycletls');
// Typescript: import initCycleTLS from 'cycletls';

(async () => {
  // Initiate CycleTLS
  const cycleTLS = await initCycleTLS();

  // Send request
  const response = await cycleTLS('https://match.yuanrenxue.com/api/match/19?page=1', {
    body: '',
    ja3: '771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-49161-	  	  49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-21,29-23-     24-25-256-257,0',
    userAgent: 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101       Firefox/87.0',
    timeout: 2,
    // proxy: 'http://username:password@hostname.com:443'
  }, 'get');

  console.log(response);

  // Cleanly exit CycleTLS
  cycleTLS.exit();

})();

效果

三.结语

好了，上面列举的这些ja3指纹工具实现相信能够应付绝大多是情况,兄弟们可以自行测试效果,如果遇到更多的情况，还得详细的分析，去进行魔改测试。
