<h1><a name="notes">NOTES</a></h1>
|
|
<p>In order to verify the certificates presented by the peer, trusted CA
|
|
certificates must be accessed. These CA certificates are made available
|
|
via lookup methods, handled inside the X509_STORE. From the X509_STORE
|
|
the X509_STORE_CTX used when verifying certificates is created.</p>
|
|
<p>Typically the trusted certificate store is handled indirectly via using
|
|
<em>SSL_CTX_load_verify_locations(3)</em>.
|
|
Using the <code>SSL_CTX_set_cert_store()</code> and <code>SSL_CTX_get_cert_store()</code> functions
|
|
it is possible to manipulate the X509_STORE object beyond the
|
|
<em>SSL_CTX_load_verify_locations(3)</em>
|
|
call.</p>
|
|
<p>Currently no detailed documentation on how to use the X509_STORE
|
|
object is available. Not all members of the X509_STORE are used when
|
|
the verification takes place. So will e.g. the <code>verify_callback()</code> be
|
|
overridden with the <code>verify_callback()</code> set via the
|
|
<em>SSL_CTX_set_verify(3)</em> family of functions.
|
|
This document must therefore be updated when documentation about the
|
|
X509_STORE object and its handling becomes available.</p>
|
|
<p><code>SSL_CTX_set_cert_store()</code> does not increment the <strong>store</strong>'s reference
|
|
count, so it should not be used to assign an X509_STORE that is owned
|
|
by another SSL_CTX.</p>
|
|
<p>To share X509_STOREs between two SSL_CTXs, use <code>SSL_CTX_get_cert_store()</code>
|
|
to get the X509_STORE from the first SSL_CTX, and then use
|
|
SSL_CTX_set1_cert_store() to assign to the second SSL_CTX and
|
|
increment the reference count of the X509_STORE.</p>

<h1><a name="restrictions">RESTRICTIONS</a></h1>
|
|
<p>The X509_STORE structure used by an SSL_CTX is used for verifying peer
|
|
certificates and building certificate chains, it is also shared by
|
|
every child SSL structure. Applications wanting finer control can use
|
|
functions such as SSL_CTX_set1_verify_cert_store() instead.</p>
