<p>Represents an elliptic curve for use by elliptic-curve cipher algorithms.</p>
<p>The class <a href="qsslellipticcurve.html">QSslEllipticCurve</a> represents an elliptic curve for use by elliptic-curve cipher algorithms.</p>
<p>Elliptic curves can be constructed from a "short name" (SN) (<a href="qsslellipticcurve.html#fromShortName">fromShortName</a>()), and by a call to <a href="qsslconfiguration.html#supportedEllipticCurves">QSslConfiguration::supportedEllipticCurves</a>().</p>
<p><a href="qsslellipticcurve.html">QSslEllipticCurve</a> instances can be compared for equality and can be used as keys in <a href="../qtcore/qhash.html#qhash">QHash</a> and <a href="../qtcore/qset.html">QSet</a>. They cannot be used as key in a <a href="../qtcore/qmap.html">QMap</a>.</p>
