<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p>The OpenSSL <strong>ssl</strong> library implements the Secure Sockets Layer (SSL v2/v3) and
|
|
Transport Layer Security (TLS v1) protocols. It provides a rich API which is
|
|
documented here.</p>
|
|
<p>An <strong>SSL_CTX</strong> object is created as a framework to establish
|
|
TLS/SSL enabled connections (see <a href="#ssl_ctx_new">SSL_CTX_new(3)</a>).
|
|
Various options regarding certificates, algorithms etc. can be set
|
|
in this object.</p>
|
|
<p>When a network connection has been created, it can be assigned to an
|
|
<strong>SSL</strong> object. After the <strong>SSL</strong> object has been created using
|
|
<a href="#ssl_new">SSL_new(3)</a>, <a href="#ssl_set_fd">SSL_set_fd(3)</a> or
|
|
<a href="#ssl_set_bio">SSL_set_bio(3)</a> can be used to associate the network
|
|
connection with the object.</p>
|
|
<p>When the TLS/SSL handshake is performed using
|
|
<a href="#ssl_accept">SSL_accept(3)</a> or <a href="#ssl_connect">SSL_connect(3)</a>
|
|
respectively.
|
|
<em>SSL_read_ex(3)</em>, <a href="#ssl_read">SSL_read(3)</a>, <em>SSL_write_ex(3)</em> and <a href="#ssl_write">SSL_write(3)</a> are
|
|
used to read and write data on the TLS/SSL connection.
|
|
<a href="#ssl_shutdown">SSL_shutdown(3)</a> can be used to shut down the
|
|
TLS/SSL connection.</p>

<h1><a name="data_structures">DATA STRUCTURES</a></h1>
|
|
<p>Currently the OpenSSL <strong>ssl</strong> library functions deals with the following data
|
|
structures:</p>
|
|
<dl>
|
|
<dt><strong><a name="ssl_method" class="item"><strong>SSL_METHOD</strong> (SSL Method)</a></strong></dt>
|
|
|
|
<dd>
|
|
<p>This is a dispatch structure describing the internal <strong>ssl</strong> library
|
|
methods/functions which implement the various protocol versions (SSLv3
|
|
TLSv1, ...). It's needed to create an <strong>SSL_CTX</strong>.</p>
|
|
</dd>
|
|
<dt><strong><a name="ssl_cipher" class="item"><strong>SSL_CIPHER</strong> (SSL Cipher)</a></strong></dt>
|
|
|
|
<dd>
|
|
<p>This structure holds the algorithm information for a particular cipher which
|
|
are a core part of the SSL/TLS protocol. The available ciphers are configured
|
|
on a <strong>SSL_CTX</strong> basis and the actual ones used are then part of the
|
|
<strong>SSL_SESSION</strong>.</p>
|
|
</dd>
|
|
<dt><strong><a name="ssl_ctx" class="item"><strong>SSL_CTX</strong> (SSL Context)</a></strong></dt>
|
|
|
|
<dd>
|
|
<p>This is the global context structure which is created by a server or client
|
|
once per program life-time and which holds mainly default values for the
|
|
<strong>SSL</strong> structures which are later created for the connections.</p>
|
|
</dd>
|
|
<dt><strong><a name="ssl_session" class="item"><strong>SSL_SESSION</strong> (SSL Session)</a></strong></dt>
|
|
|
|
<dd>
|
|
<p>This is a structure containing the current TLS/SSL session details for a
|
|
connection: <strong>SSL_CIPHER</strong>s, client and server certificates, keys, etc.</p>
|
|
</dd>
|
|
<dt><strong><a name="ssl" class="item"><strong>SSL</strong> (SSL Connection)</a></strong></dt>
|
|
|
|
<dd>
|
|
<p>This is the main SSL/TLS structure which is created by a server or client per
|
|
established connection. This actually is the core structure in the SSL API.
|
|
At run-time the application usually deals with this structure which has
|
|
links to mostly all other structures.</p>

<h1><a name="header_files">HEADER FILES</a></h1>
|
|
<p>Currently the OpenSSL <strong>ssl</strong> library provides the following C header files
|
|
containing the prototypes for the data structures and functions:</p>
|
|
<dl>
|
|
<dt><strong><a name="ssl_h" class="item"><strong>ssl.h</strong></a></strong></dt>
|
|
|
|
<dd>
|
|
<p>This is the common header file for the SSL/TLS API. Include it into your
|
|
program to make the API of the <strong>ssl</strong> library available. It internally
|
|
includes both more private SSL headers and headers from the <strong>crypto</strong> library.
|
|
Whenever you need hard-core details on the internals of the SSL API, look
|
|
inside this header file.</p>
|
|
</dd>
|
|
<dt><strong><a name="ssl2_h" class="item"><strong>ssl2.h</strong></a></strong></dt>

</dd>
|
|
<dt><strong><a name="ssl3_h" class="item"><strong>ssl3.h</strong></a></strong></dt>
|
|
|
|
<dd>
|
|
<p>This is the sub header file dealing with the SSLv3 protocol only.
|
|
<em>Usually you don't have to include it explicitly because
|
|
it's already included by ssl.h</em>.</p>
|

</dd>

<dt><strong><a name="tls1_h" class="item"><strong>tls1.h</strong></a></strong></dt>
