<section class="description">
<p>The <a href="../X509.html"><code>X509</code></a> certificate store holds trusted CA certificates used to verify peer certificates.</p>
<p>The easiest way to create a useful certificate store is:</p>
<pre class="ruby"><span class="ruby-identifier">cert_store</span> = <span class="ruby-constant">OpenSSL</span><span class="ruby-operator">::</span><span class="ruby-constant">X509</span><span class="ruby-operator">::</span><span class="ruby-constant">Store</span>.<span class="ruby-identifier">new</span>
<span class="ruby-identifier">cert_store</span>.<span class="ruby-identifier">set_default_paths</span>
</pre>
<p>This will use your system’s built-in certificates.</p>
<p>If your system does not have a default set of certificates you can obtain a set extracted from Mozilla CA certificate store by cURL maintainers here: <a href="https://curl.haxx.se/docs/caextract.html">curl.haxx.se/docs/caextract.html</a> (You may wish to use the firefox-db2pem.sh script to extract the certificates from a local install to avoid man-in-the-middle attacks.)</p>
<p>After downloading or generating a cacert.pem from the above link you can create a certificate store from the pem file like this:</p>
<pre class="ruby"><span class="ruby-identifier">cert_store</span> = <span class="ruby-constant">OpenSSL</span><span class="ruby-operator">::</span><span class="ruby-constant">X509</span><span class="ruby-operator">::</span><span class="ruby-constant">Store</span>.<span class="ruby-identifier">new</span>
<span class="ruby-identifier">cert_store</span>.<span class="ruby-identifier">add_file</span> <span class="ruby-string">'cacert.pem'</span>
</pre>
<p>The certificate store can be used with an SSLSocket like this:</p>
<pre class="ruby"><span class="ruby-identifier">ssl_context</span> = <span class="ruby-constant">OpenSSL</span><span class="ruby-operator">::</span><span class="ruby-constant">SSL</span><span class="ruby-operator">::</span><span class="ruby-constant">SSLContext</span>.<span class="ruby-identifier">new</span>
<span class="ruby-identifier">ssl_context</span>.<span class="ruby-identifier">verify_mode</span> = <span class="ruby-constant">OpenSSL</span><span class="ruby-operator">::</span><span class="ruby-constant">SSL</span><span class="ruby-operator">::</span><span class="ruby-constant">VERIFY_PEER</span>
<span class="ruby-identifier">ssl_context</span>.<span class="ruby-identifier">cert_store</span> = <span class="ruby-identifier">cert_store</span>
<span class="ruby-identifier">tcp_socket</span> = <span class="ruby-constant">TCPSocket</span>.<span class="ruby-identifier">open</span> <span class="ruby-string">'example.com'</span>, <span class="ruby-value">443</span>
<span class="ruby-identifier">ssl_socket</span> = <span class="ruby-constant">OpenSSL</span><span class="ruby-operator">::</span><span class="ruby-constant">SSL</span><span class="ruby-operator">::</span><span class="ruby-constant">SSLSocket</span>.<span class="ruby-identifier">new</span> <span class="ruby-identifier">tcp_socket</span>, <span class="ruby-identifier">ssl_context</span>

<p>The callback can use <a href="StoreContext.html#method-i-error-3D"><code>StoreContext#error=</code></a> to change the error code as needed. The callback must return either true or false.</p>
