Member Function Documentation

NeedConversions()

bool EcPrecomputation< ECP >::NeedConversions ( ) const

inlinevirtual

Determines if elements needs conversion.

Returns

true if the element needs conversion, false otherwise

NeedConversions determines if an element must convert between representations.

Reimplemented from DL_GroupPrecomputation< ECP::Point >.

Definition at line 134 of file ecp.h.

ConvertIn()

Element EcPrecomputation< ECP >::ConvertIn ( const Element & v ) const

inlinevirtual

Converts an element between representations.

Parameters

v	element to convert

Returns

an element converted to an alternate representation for internal use

ConvertIn is used when an element must convert between representations.

Reimplemented from DL_GroupPrecomputation< ECP::Point >.

Definition at line 135 of file ecp.h.

ConvertOut()

Element EcPrecomputation< ECP >::ConvertOut ( const Element & v ) const

inlinevirtual

Converts an element between representations.

Parameters

v	element to convert

Returns

an element converted from an alternate representation

Reimplemented from DL_GroupPrecomputation< ECP::Point >.

Definition at line 137 of file ecp.h.

GetGroup()

const AbstractGroup< Element > & EcPrecomputation< ECP >::GetGroup ( ) const

inlinevirtual

Retrieves AbstractGroup interface.

Returns

GetGroup() returns the AbstractGroup interface

Implements DL_GroupPrecomputation< ECP::Point >.

Definition at line 139 of file ecp.h.

BERDecodeElement()

Element EcPrecomputation< ECP >::BERDecodeElement ( BufferedTransformation & bt ) const

inlinevirtual

Decodes element in DER format.

Parameters

bt	BufferedTransformation object

Returns

element in the group

Implements DL_GroupPrecomputation< ECP::Point >.

Definition at line 140 of file ecp.h.

DEREncodeElement()

void EcPrecomputation< ECP >::DEREncodeElement ( BufferedTransformation & bt, const Element & P ) const

inlinevirtual

Encodes element in DER format.

Parameters

bt	BufferedTransformation object
P	Element to encode

Implements DL_GroupPrecomputation< ECP::Point >.

Definition at line 141 of file ecp.h.

SetCurve()

void EcPrecomputation< ECP >::SetCurve ( const ECP & ec )

inline

Set the elliptic curve.

Parameters

ec	ECP derived class

SetCurve() is not inherited

Definition at line 146 of file ecp.h.

GetCurve()

const ECP & EcPrecomputation< ECP >::GetCurve ( ) const

inline

Get the elliptic curve.

Returns

ECP curve

GetCurve() is not inherited
