\brief Represents an elliptic curve for use by elliptic-curve cipher algorithms.
\reentrant
\ingroup network
\ingroup ssl
\inmodule QtNetwork
The class QSslEllipticCurve represents an elliptic curve for use by
elliptic-curve cipher algorithms.
Elliptic curves can be constructed from a "short name" (SN) (fromShortName()),
and by a call to QSslSocket::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.
*/
/*!
\fn QSslEllipticCurve::QSslEllipticCurve()
Constructs an invalid elliptic curve.

/*!
\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.
If the given \a name is not supported, returns an invalid QSslEllipticCurve instance.
\note The OpenSSL implementation of this function treats the name case-sensitively.

/*!
\fn QSslEllipticCurve QSslEllipticCurve::fromLongName(const QString &name)
Returns an QSslEllipticCurve instance representing the named curve \a name.
The \a name is a long name for the curve, whose exact spelling depends on the
SSL implementation.
If the given \a name is not supported, returns an invalid QSslEllipticCurve instance.
\note The OpenSSL implementation of this function treats the name case-sensitively.

used in the key exchange when using an elliptic curve cipher with TLS;
false otherwise.
