Detailed Description

Represents an elliptic curve for use by elliptic-curve cipher algorithms.

Since

5.5

\reentrant

\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 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.

QSslEllipticCurve()

QSslEllipticCurve::QSslEllipticCurve ( )

inlineconstexprnoexcept

Constructs an invalid elliptic curve.

Member Function Documentation

fromLongName()

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()

Definition at line 83 of file qsslellipticcurve.cpp.

fromShortName()

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 (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.

isTlsNamedCurve()

bool QSslEllipticCurve::isTlsNamedCurve ( ) const

noexcept

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.

Definition at line 138 of file qsslellipticcurve.cpp.

isValid()

bool QSslEllipticCurve::isValid ( ) const

inlineconstexprnoexcept

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

Definition at line 31 of file qsslellipticcurve.h.

longName()

QString QSslEllipticCurve::longName ( ) const

nodiscard

Returns the conventional long name for this curve.

If this curve is invalid, returns an empty string.
