<!-- $$$QSslCertificate-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qsslcertificate.html">QSslCertificate</a> class provides a convenient API for an X509 certificate.</p>
<p><a href="qsslcertificate.html">QSslCertificate</a> 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 <a href="qsslcertificate.html">QSslCertificate</a>. The most common way is to call <a href="qsslsocket.html#peerCertificate">QSslSocket::peerCertificate</a>(), which returns a <a href="qsslcertificate.html">QSslCertificate</a> 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, <a href="qsslcertificate.html">QSslCertificate</a> constructs a null certificate. 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, <a href="qsslcertificate.html">QSslCertificate</a> 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>

If a <i>passPhrase</i> is specified then this will be used to decrypt the bundle. Returns <code>true</code> if the PKCS#12 file was successfully loaded.</p>
<p><b>Note: </b>The <i>device</i> must be open and ready to be read from.</p><p>This function was introduced in Qt 5.4.</p>
