Detailed Description

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 QSslConfiguration::supportedEllipticCurves().

QSslEllipticCurve instances can be compared for equality and can be used as keys in QHash and QSet. They can not be used as key in a QMap since they can not be compared for less than.

Constructor & Destructor Documentation

constexpr QSslEllipticCurve::QSslEllipticCurve ( )
inlineconstexpr

Constructs an invalid elliptic curve.

isValid(), QSslConfiguration::supportedEllipticCurves()

Method Documentation

QSslEllipticCurve QSslEllipticCurve::fromLongName ( const QString &  name)
static

Returns an QSslEllipticCurve instance representing the named curve name. The name is a long name for the curve, whose exact spelling depends on the SSL implementation.

If the given name is not supported, returns an invalid QSslEllipticCurve instance.

Note
The OpenSSL implementation of this function treats the name case-sensitively.

longName()
QSslEllipticCurve QSslEllipticCurve::fromShortName ( const QString &  name)
static

Returns an QSslEllipticCurve instance representing the named curve name. The name is the conventional short name for the curve, as represented by RFC 4492 or as NIST short names. The actual set of recognized names depends on the SSL implementation.

If the given name is not supported returns an invalid QSslEllipticCurve instance.

Note
The OpenSSL implementation of this function treats the name case-sensitively.

shortName()
bool QSslEllipticCurve::isTlsNamedCurve ( ) const

Returns true if this elliptic curve is one of the named curves that can be used in the key exchange when using an elliptic curve cipher with TLS, false otherwise.

constexpr bool QSslEllipticCurve::isValid ( ) const
inlineconstexpr

Returns true if this elliptic curve is a valid curve, false otherwise.

QString QSslEllipticCurve::longName ( ) const
nodiscard

Returns the conventional long name for this curve. If this curve is invalid, returns an empty string.

See also
shortName()
QString QSslEllipticCurve::shortName ( ) const
nodiscard

Returns the conventional short name for this curve. If this curve is invalid, returns an empty string.

bool operator!= ( QSslEllipticCurve  lhs,
QSslEllipticCurve  rhs 
)
related

Returns true if the curve lhs represents a different curve than rhs, false otherwise.

QDebug operator<< ( QDebug  debug,
QSslEllipticCurve  curve 
)
related

Writes the given curve to the debug stream.

bool operator== ( QSslEllipticCurve  lhs,
QSslEllipticCurve  rhs 
)
friend

Returns true if the curve lhs represents the same curve of rhs;

uint qHash ( QSslEllipticCurve  curve,
uint  seed = 0 
)
friend

Returns an hash value for the given curve using seed to seed the calculation.
