Public Structure ECCurve

Inheritance: Object

ValueType
ECCurve

Attributes: UnsupportedOSPlatformAttribute

Remarks

Use the CurveType field to determine whether the curve is a named curve or an explicit curve (either a prime or a characteristic 2 curve).

Fields

A	The first coefficient for an explicit curve. `A` for short Weierstrass, Montgomery, and Twisted Edwards curves.
B	The second coefficient for an explicit curve. `B` for short Weierstrass and `d` for Twisted Edwards curves.
Cofactor	The cofactor of the curve.
CurveType	Identifies the composition of the ECCurve object.
G	The generator, or base point, for operations on the curve.
Hash	The name of the hash algorithm which was used to generate the curve coefficients (A and B) from the Seed under the ANSI X9.62 generation algorithm. Applies only to explicit curves.
Order	The order of the curve. Applies only to explicit curves.
Polynomial	The curve polynomial. Applies only to characteristic 2 curves.
Prime	The prime specifying the base field. Applies only to prime curves.
Seed	The seed value for coefficient generation under the ANSI X9.62 generation algorithm. Applies only to explicit curves.

Properties

IsCharacteristic2	Gets a value that indicates whether the curve type indicates an explicit characteristic 2 curve.
IsExplicit	Gets a value that indicates whether the curve type indicates an explicit curve (either prime or characteristic 2).
IsNamed	Gets a value that indicates whether the curve type indicates a named curve.
IsPrime	Gets a value that indicates whether the curve type indicates an explicit prime curve.
Oid	Gets the identifier of a named curve.

Methods

CreateFromFriendlyName(String)	Creates a named curve using the specified friendly name of the identifier.
CreateFromOid(Oid)	Creates a named curve using the specified Oid object.
CreateFromValue(String)	Creates a named curve using the specified dotted-decimal representation of the identifier.
Validate()	Validates the integrity of the current curve. Throws a CryptographicException exception if the structure is not valid.
