我之前的文章介绍了SSL指纹识别

很多人来问我BYPass的方法
主流的BYPASS方法有两大类:
-
使用定制ja3的网络库 go在这块的库比较流行(比如go的库requests还有cycletls) 缺点在于,就是得用go语言开发(cycletls有nodejs的但是也是开了一个go语言的一个websocket)
-
魔改curl,最有名的就是curl-impersonate 对应win版本的 https://github.com/depler/curl-impersonate-win 缺点就是编译复杂,使用方式上,得用包装curl的第三方库,用的多就是python的pycurl 其他语言的比较少
正好五一有时间,站在巨人们的肩膀上我用go语言开发了一个代理服务.
只需要设置这个代理服务,就可以自定义ja3参数
这样任何语言都可以直接用了,而且只需要加一个webproxy即可
具体效果可以往下看
解压后如上图,包含2个文件
-
ja3proxy.exe ja3proxy是go开发的一个控制台程序 -
localhost_root.pfx 本地证书
(测试加我要)
为了方便本机测试,先安装localhost_root.pfx证书, (如果不安装证书,也可以运行,只不过你需要将请求忽略ssl verify)
证书密码为123456
选择位置为:受信任的根证书颁发机构
安装成功后,使用如下命令 运行ja3proxy.exe
ja3proxy.exe -pfxFile=localhost_root.pfx -pfxPwd=123456
支持的参数共有如下:
-
pfxFile (pfx类型证书) -
pfxPwd (pfx证书的密码) -
authName 如果你要开启ja3proxy代理服务的basicauth认证,可以设置 -
authPwd (同上) -
httpPort (ja3proxy代理的http端口,默认为8080) -
httpsPort (ja3proxy代理的https端口,默认为8443) -
certFile 非pfx类型证书可以设置 -
keyFile 同上
ja3proxy运行成功后,测试代码如下:
var proxy = new WebProxy
{
// 这就是我们的ja3proxy
Address = new Uri($"http://localhost:8080")
};
var httpClientHandler = new HttpClientHandler
{
Proxy = proxy,
};
// 因为我们再上面把证书添加到本机受信任了 所以这行代码不需要,如果你不操作受信任证书的话,就需要
//httpClientHandler.ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator;
var client2 = new HttpClient(handler: httpClientHandler, disposeHandler: true);
// 设置ja3指纹
client2.DefaultRequestHeaders.Add("tls-ja3","771,4865-4866-4867-49195-49199-49196-49200-52393-52392-49171-49172-156-157-47-53,17513-10-18-11-51-13-27-0-35-65281-43-16-45-5-23-21,29-23-24,0");
// 设置ja3proxy执行请求的超时
client2.DefaultRequestHeaders.Add("tls-timeout","10");
// 设置ja3proxy执行请求用代理,设置后请求目标服务器拿到的就是代理ip
// client2.DefaultRequestHeaders.Add("tls-proxy","http://252.45.26.333:5543");
// 设置当前请求的useragent
client2.DefaultRequestHeaders.UserAgent.ParseAdd("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.54 Safari/537.36");
var result = await client2.GetStringAsync("https://kawayiyi.com/tls");
Console.WriteLine(result);
执行后,校验ja3一致

nodejs测试
const request = require('request');
const options = {
url:'https://kawayiyi.com/tls',
method: 'GET',
headers: {

},
proxy: 'http://localhost:8080',
strictSSL:false
};
request.get(options, (error, response, body) => {
if (error) {
console.error(error);
return;
}
console.log('body:', body);
});
h2的header顺序:m,a,s,p 和chrome保持一致
原理
ja3proxy(是一个中间人)接管你的请求,然后自己去目标建立tls,clienthello就用你指定的ja3参数
