Member Function Documentation

GetVoidValue()

template<class T >

bool DL_PublicKey< T >::GetVoidValue ( const char * name, const std::type_info & valueType, void * pValue ) const

inline

Get a named value.

Parameters

name	the name of the object or value to retrieve
valueType	reference to a variable that receives the value
pValue	void pointer to a variable that receives the value

Returns

true if the value was retrieved, false otherwise

GetVoidValue() retrieves the value of name if it exists.

Note

GetVoidValue() is an internal function and should be implemented by derived classes. Users should use one of the other functions instead.

AssignFrom()

template<class T >

void DL_PublicKey< T >::AssignFrom

(

const NameValuePairs &

source

)

Initialize or reinitialize this key.

Parameters

source

NameValuePairs to assign

Definition at line 1192 of file pubkey.h.

GetPublicElement()

template<class T >

virtual const Element & DL_PublicKey< T >::GetPublicElement ( ) const

inlinevirtual

Retrieves the public element.

Returns

the public element

Definition at line 1089 of file pubkey.h.

SetPublicElement()

template<class T >

virtual void DL_PublicKey< T >::SetPublicElement ( const Element & y )

inlinevirtual

Sets the public element.

Parameters

y	the public element

Definition at line 1093 of file pubkey.h.

ExponentiatePublicElement()

template<class T >

virtual Element DL_PublicKey< T >::ExponentiatePublicElement ( const Integer & exponent ) const

inlinevirtual

Exponentiates this element.

Parameters

exponent

the exponent to raise the base

Returns

the public element raised to the exponent

Definition at line 1098 of file pubkey.h.

CascadeExponentiateBaseAndPublicElement()

template<class T >

virtual Element DL_PublicKey< T >::CascadeExponentiateBaseAndPublicElement ( const Integer & baseExp, const Integer & publicExp ) const

inlinevirtual

Exponentiates an element.

Parameters

baseExp	the first exponent
publicExp	the second exponent

Returns

the public element raised to the exponent

CascadeExponentiateBaseAndPublicElement raises the public element to the base element and precomputation.

Definition at line 1110 of file pubkey.h.

GetPublicPrecomputation()

template<class T >

virtual const DL_FixedBasePrecomputation< T > & DL_PublicKey< T >::GetPublicPrecomputation ( ) const

pure virtual

Accesses the public precomputation.

GetPublicPrecomputation returns a const reference, while AccessPublicPrecomputation returns a non-const reference. Must be overridden in derived classes.

Implemented in DL_PublicKeyImpl< GP >, and DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >.

AccessPublicPrecomputation()

template<class T >

virtual DL_FixedBasePrecomputation< T > & DL_PublicKey< T >::AccessPublicPrecomputation ( )

pure virtual

Accesses the public precomputation.

GetPublicPrecomputation returns a const reference, while AccessPublicPrecomputation returns a non-const reference. Must be overridden in derived classes.

Implemented in DL_PublicKeyImpl< GP >, and DL_PublicKeyImpl< DL_GroupParameters_EC< EC > >.
