+# <return>explication</return> SSL/TLS
+
+## Client
+For use/enable ``SSL/TLS`` on ``Netly`` with ``TcpClient`` instance use code bellow.
+
+<return>Warning</return> When you enable ``SSL/TLS`` and your server not use ``SSL/TLS`` you connection will be closed.
+
+- Default config
+	```cs
+	using Netly;
+
+	TcpClient client = new TcpClient(framing: true);
+
+	// Enable SSL/TLS connection.
+	client.UseEncryption(true);
+	```
+
+- Custom validatiion
+	```cs
+	using Netly;
+
+	TcpClient client = new TcpClient(framing: true);
+
+	// Enable SSL/TLS connection.
+	client.UseEncryption(true, Validator);
+
+	bool Validator(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
+	{
+
+	#if false
+		// Default behaviour
+		return true;
+	#endif
+
+		// Custom validation
+		// Source: https://learn.microsoft.com/dotnet/api/system.net.security.sslstream
+
+		if (sslPolicyErrors == SslPolicyErrors.None) {

+
+        // refuse connection
+        return false;
+
+	}
+	```
+
+## Server
+For use/enable ``SSL/TLS`` on ``Netly`` with ``TcpServer`` instance use code bellow.
+
+<return>Warning</return> When you enable ``SSL/TLS`` and your client not use ``SSL/TLS`` you client connection will be closed.
+
+
+```cs
+    // Warning: See about generate pfx on SSL/TLS page now we will see about startup this!
+    // Warning: Convert pfx file for bytes only using UTF8 for prevent erros
+
+	byte[] pfx = <class>.<method-get-fpx-buffer>();
+    string pfxPassword = <class>.<method-get-pfx-password>();
+
+    // Enable SSL/TLS
+    TcpServer.UseEncryption(pfx, pfxPassword, SslProtocols.Tls12); // TLS v1.2
+
+	// If password or PFX buffer is invalid you will receive error message on <TcpServer.OnError(Actiion<Exception> callback)>
+```
+
+## Create PFX (PKCS #12)
+* Requirement ``OpenSSL``
+	- linux: Use package manager
+		- Ubuntu: ``sudo apt install openssl`` or ``sudo apt install libssl-dev``
+		- Windows:
+			- Download windows: https://wiki.openssl.org/index.php/Binaries
+			- Add OpenSSL folder on ``path`` (``Environment Variables``)
+	- Generate ``PFX (PKCS #12)``: https://www.ibm.com/docs/en/api-connect/10.0.x?topic=overview-generating-self-signed-certificate-using-openssl
