大家好，欢迎来到IT知识分享网。
只需要在命令行加 –tls即可：

看下矿池的IP：

来自 131.153.76.130 的回复: 字节=32 时间=233ms TTL=43
131.153.76.130 的 Ping 统计信息:

往返行程的估计时间(以毫秒为单位):

然后在挖矿过程中抓包，可以看到，在通信过程中完全使用了tls1.3的通信流量：
这下通过流量检测有些麻烦了！
补充，我又在挖矿过程中进行了一次抓包，

虽然cmd里提示tls1.3，但是我看到却是tls1.2，咋回事？
我又试了几次，因为有动态dns，这次IP是131.153.76.130，不过还是tls1.3
又试了几次，还是tls1.3

从这里可以看出，支持tls1.2，和tls1.3
xmrig::Client::Tls::Tls(Client *client) :
m_client(client)
{
m_ctx = SSL_CTX_new(SSLv23_method());
assert(m_ctx != nullptr);
if (!m_ctx) {
return;
}
m_write = BIO_new(BIO_s_mem());
m_read = BIO_new(BIO_s_mem());
SSL_CTX_set_options(m_ctx, SSL_OP_NO_SSLv2 | SSL_OP_NO_SSLv3);
}
openssl的使用可以参考： https://www.cnblogs.com/sxmcACM/p/6082907.html
/* ---------------------------------------------------------- * 51 * 发送SSL2 SSL3 TLS 1.0 TLS 2.0 TLS 3.0 与服务器建链 * 52 * ---------------------------------------------------------- */ 53 method = SSLv23_client_method(); 54 55 /* ---------------------------------------------------------- * 56 * 创建一个新的SSL上下文 * 57 * ---------------------------------------------------------- */ 58 if ((ctx = SSL_CTX_new(method)) == NULL) 59 BIO_printf(outbio, "Unable to create a new SSL context structure.\n"); 60
总结起来就是说，xmrig使用openssl的tls客户端进行加密通信。
