详细描述

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 .

注意： This class is currently only supported in OpenSSL.

[constexpr noexcept] QSslEllipticCurve:: QSslEllipticCurve ()

Constructs an invalid elliptic curve.

另请参阅 isValid () 和 QSslConfiguration::supportedEllipticCurves ().

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

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

若给定 name is not supported, returns an invalid QSslEllipticCurve 实例。

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

另请参阅 longName ().

[static] QSslEllipticCurve QSslEllipticCurve:: fromShortName (const QString & name )

返回 QSslEllipticCurve instance representing the named curve name 。 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.

若给定 name is not supported, returns an invalid QSslEllipticCurve 实例。

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

另请参阅 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.

另请参阅 shortName ().

QString QSslEllipticCurve:: shortName () const

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

另请参阅 longName ().

[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 到 debug 对象 debug 为调试目的。

另请参阅 调试技术 .

[constexpr noexcept] bool operator== ( QSslEllipticCurve lhs , QSslEllipticCurve rhs )

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