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 cannot be used as key in a QMap.
Note: This class is currently only supported in OpenSSL.
Member Function Documentation
[constexpr noexcept] QSslEllipticCurve::QSslEllipticCurve()
Constructs an invalid elliptic curve.
See also isValid() and QSslConfiguration::supportedEllipticCurves().
[static] QSslEllipticCurve QSslEllipticCurve::fromLongName(const QString &name)
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.
See also longName().
[static] QSslEllipticCurve QSslEllipticCurve::fromShortName(const QString &name)
Returns an QSslEllipticCurve instance representing the named curve name. The name is the conventional short name for the curve, as represented by RFC 4492 (for instance secp521r1), or as NIST short names (for instance P-256). 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.
See also shortName().
[noexcept] 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 noexcept] bool QSslEllipticCurve::isValid() const
Returns true if this elliptic curve is a valid curve, false otherwise.
QString QSslEllipticCurve::longName() const
Returns the conventional long name for this curve. If this curve is invalid, returns an empty string.
See also shortName().
QString QSslEllipticCurve::shortName() const
Returns the conventional short name for this curve. If this curve is invalid, returns an empty string.
See also longName().
Related Non-Members
[constexpr noexcept] bool operator!=(QSslEllipticCurve lhs, QSslEllipticCurve rhs)
Returns true if the curve lhs represents a different curve than rhs; false otherwise.
QDebug operator<<(QDebug debug, QSslEllipticCurve curve)
Writes the elliptic curve curve into the debug object debug for debugging purposes.
See also Debugging Techniques.
[constexpr noexcept] bool operator==(QSslEllipticCurve lhs, QSslEllipticCurve rhs)
Returns true if the curve lhs represents the same curve of rhs;
