Elliptic curves can be constructed from a "short name" (SN) (fromShortName()), and by a call to QSslConfiguration::supportedEllipticCurves(). QSslEllipticCurve instances can be compared for equality and can be used as keys in QHash and QSet. They cannot be used as key in a QMap. \note This class is currently only supported in OpenSSL. */ /*! \fn QSslEllipticCurve::QSslEllipticCurve() Constructs an invalid elliptic curve. \sa isValid(), QSslConfiguration::supportedEllipticCurves() */ /*! \fn QSslEllipticCurve QSslEllipticCurve::fromShortName(const QString &name) Returns an QSslEllipticCurve instance representing the named curve \a name. The \a name is the conventional short name for the curve, as represented by RFC 4492 (for instance \c{secp521r1}), or as NIST short names (for instance \c{P-256}). The actual set of recognized names depends on the SSL implementation.
