<p>To sign a file using X509 certificate,
an application need to associate the certificate (or certificates)
with the private key using one of the following functions:
</p>
<p></p>
<ul>
<li><p> <a href="xmlsec-openssl-app.html#XMLSECOPENSSLAPPKEYCERTLOAD">xmlSecOpenSSLAppKeyCertLoad</a> - loads
certificate from a file and adds to the key;
</p></li>
<li><p> <a href="xmlsec-openssl-app.html#XMLSECOPENSSLAPPPKCS12LOAD">xmlSecOpenSSLAppPkcs12Load</a> -
loads private key and all the certificates associated with it from a PKCS12 file;
</p></li>
<li><p> <a href="xmlsec-keys.html#XMLSECKEYADOPTDATA">xmlSecKeyAdoptData</a> - low level
function to add key data (including X509 key data) to the key.
</p></li>
</ul>
<div class="EXAMPLE">
<a name="AEN535"></a><p><b>Example 1. Loading private key and X509 certificate.</b></p>
