# Chapter 11 - SSL Filter
-To be completed...
+The **SslFilter** is the filter in charge of managing the ecnryption and decryption of data sent through a secured connection. Whenever you need to establish a secured connection, or to transform an existing connection to make it secure, you have to add the **SslFilte** in your filter chain.
+
+As any session can modify it's message filter chain at will, it allows for protocols like **startTLS** to be used on an opened connection.
+
+## Basic usage
+
+If you want your application to support **/TLS**, just add the **SslFilter** in your chain :
+
+ ...
+ DefaultIoFilterChainBuilder chain = acceptor.getFilterChain();
+ SslFilter sslFilter = new SslFilter(sslContext);
+ chain.addFirst("sslFilter", sslFilter);
+ ...
+
+You obviously need a **SslContext** instance too :
+
+ SSLContext sslContext;
+
+ try
+ {
+ // Initialize the SSLContext to work with our key managers.
+ sslContext = SSLContext.getInstance( "TLS" );
+ sslContext.init( ... ); // Provide the needed KeyManager[], TrustManager[] and SecureRandom instances
+ }
+ catch ( Exception e )
+ {
+ // Handle your exception
+ }
+
+This is up to you to provide the **KeyManager**, **TrustManager** and **SecureRandom** instances.
+
+be sure to inject the **SslFilter** on teh first position in your chain !
+
+## A bit of theory
+
+If you want to get a deeper understanding on how it all works, please read the following paragraphs...
+
+### SSL Basics
+
+We are not going to explain how **SSL** works, there are very [good books](http://www.amazon.com/SSL-TLS-Designing-Building-Systems/dp/0201615983) outhere. We will just give a quick introduction on how it works and how it is implemented in MINA.
+
+First of all, you have to understand that **SSL/TLS** is a protocol defined in **RFCs** : [TLS 1.0](https://www.rfc-editor.org/rfc/rfc2246.txt), [TLS 1.1](https://www.rfc-editor.org/rfc/rfc4346.txt) and [TLS 1.2](https://www.rfc-editor.org/rfc/rfc5246.txt). There is a [TLS 1.3](https://tlswg.github.io/tls13-spec/) draft being worked on...
+
+It was initially developed by **Netscape**, and named **SSL** (from 1.0 to 3.0), before becoming **TLS**. Nowadays, ***SSL 2.0** and **SSL 3.0** have been deprecated and should not be used.
+
+
+### The SSL/TLS protocol
+
+As it's a protocol, it requires some dialog between a client and a server. This is all what **SSL/TLS** is about : describing this dialog.
+
+It's enough to know that any secured exchange is precluded by a negociation phase, called the **Handshake**, which role is to come to an agreement between the client and the server on what will be the encryption method to use. A basic **SSL/TLS** session will be something that looks like :
