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.
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().
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.
Returns true if this elliptic curve is a valid curve, false otherwise.
Returns the conventional long name for this curve. If this curve is invalid, returns an empty string.
See also shortName().
Returns the conventional short name for this curve. If this curve is invalid, returns an empty string.
See also longName().
[since 5.5] bool operator!=(QSslEllipticCurve lhs, QSslEllipticCurve rhs)
Returns true if the curve lhs represents a different curve than rhs; false otherwise.
This function was introduced in Qt 5.5.
[since 5.5] QDebug operator<<(QDebug debug, QSslEllipticCurve curve)
Writes the elliptic curve curve into the debug object debug for debugging purposes.
This function was introduced in Qt 5.5.
See also Debugging Techniques.
[since 5.5] bool operator==(QSslEllipticCurve lhs, QSslEllipticCurve rhs)
Returns true if the curve lhs represents the same curve of rhs;
This function was introduced in Qt 5.5.
