<div class="descr">
<h2>Detailed Description</h2>
<p>The QSslCertificate class provides a convenient API for an X509 certificate.</p>
<p>QSslCertificate stores an X509 certificate, and is commonly used to verify the identity and store information about the local host, a remotely connected peer, or a trusted third party Certificate Authority.</p>
<p>There are many ways to construct a QSslCertificate. The most common way is to call <a href="qsslsocket.html#peerCertificate">QSslSocket::peerCertificate</a>(), which returns a QSslCertificate object, or <a href="qsslsocket.html#peerCertificateChain">QSslSocket::peerCertificateChain</a>(), which returns a list of them. You can also load certificates from a DER (binary) or PEM (Base64) encoded bundle, typically stored as one or more local files, or in a Qt Resource.</p>
<p>You can call <a href="qsslcertificate.html#isNull">isNull</a>() to check if your certificate is null. By default, QSslCertificate constructs a null certificate. To check if the certificate is valid, call <a href="qsslcertificate.html#isValid">isValid</a>(). A null certificate is invalid, but an invalid certificate is not necessarily null. If you want to reset all contents in a certificate, call <a href="qsslcertificate.html#clear">clear</a>().</p>
<p>After loading a certificate, you can find information about the certificate, its subject, and its issuer, by calling one of the many accessor functions, including <a href="qsslcertificate.html#version">version</a>(), <a href="qsslcertificate.html#serialNumber">serialNumber</a>(), <a href="qsslcertificate.html#issuerInfo">issuerInfo</a>() and <a href="qsslcertificate.html#subjectInfo">subjectInfo</a>(). You can call <a href="qsslcertificate.html#effectiveDate">effectiveDate</a>() and <a href="qsslcertificate.html#expiryDate">expiryDate</a>() to check when the certificate starts being effective and when it expires. The <a href="qsslcertificate.html#publicKey">publicKey</a>() function returns the certificate subject's public key as a <a href="qsslkey.html">QSslKey</a>. You can call <a href="qsslcertificate.html#issuerInfo">issuerInfo</a>() or <a href="qsslcertificate.html#subjectInfo">subjectInfo</a>() to get detailed information about the certificate issuer and its subject.</p>
<p>Internally, QSslCertificate is stored as an X509 structure. You can access this handle by calling <a href="qsslcertificate.html#handle">handle</a>(), but the results are likely to not be portable.</p>

<h3 class="fn"><a name="handle"></a><span class="type"><a href="qt.html#HANDLE-typedef">Qt::HANDLE</a></span> QSslCertificate::<span class="name">handle</span> () const</h3>
<p>Returns a pointer to the native certificate handle, if there is one, or a null pointer otherwise.</p>
<p>You can use this handle, together with the native API, to access extended information about the certificate.</p>
<p><b>Warning:</b> Use of this function has a high probability of being non-portable, and its return value may vary from platform to platform or change from minor release to minor release.</p>
<!-- @@@handle -->
<!-- $$$isNull[overload1]$$$isNull -->
<h3 class="fn"><a name="isNull"></a><span class="type">bool</span> QSslCertificate::<span class="name">isNull</span> () const</h3>
<p>Returns true if this is a null certificate (i.e., a certificate with no contents); otherwise returns false.</p>
<p>By default, <a href="qsslcertificate.html">QSslCertificate</a> constructs a null certificate.</p>
<p><b>See also </b><a href="qsslcertificate.html#isValid">isValid</a>() and <a href="qsslcertificate.html#clear">clear</a>().</p>
<!-- @@@isNull -->
<!-- $$$isValid[overload1]$$$isValid -->
<h3 class="fn"><a name="isValid"></a><span class="type">bool</span> QSslCertificate::<span class="name">isValid</span> () const</h3>
<p>Returns true if this certificate is valid; otherwise returns false.</p>
<p>Note: Currently, this function checks that the current data-time is within the date-time range during which the certificate is considered valid, and checks that the certificate is not in a blacklist of fraudulent certificates.</p>

<h3 class="fn"><a name="serialNumber"></a><span class="type"><a href="qbytearray.html">QByteArray</a></span> QSslCertificate::<span class="name">serialNumber</span> () const</h3>
<p>Returns the certificate's serial number string in decimal format. In case the serial number cannot be converted to decimal format (i.e. if it is bigger than 4294967295, which means it does not fit into 4 bytes), its hexadecimal version is returned.</p>
