59 The class QSslEllipticCurve represents an elliptic curve for use by-
60 elliptic-curve cipher algorithms.-
61-
62 Elliptic curves can be constructed from a "short name" (SN) (fromShortName()),-
63 and by a call to QSslConfiguration::supportedEllipticCurves().-
64-
65 QSslEllipticCurve instances can be compared for equality and can be used as keys-
66 in QHash and QSet. They cannot be used as key in a QMap.-

82 name for the curve, as represented by RFC 4492 (for instance \c{secp521r1}),-
83 or as NIST short names (for instance \c{P-256}). The actual set of-
84 recognized names depends on the SSL implementation.-
