Detailed Description

Discrete logarithm provider.

Note

This class is part of the provider plugin interface and should not be used directly by applications. You probably want DLGroup instead.

Constructor & Destructor Documentation

DLGroupContext()

QCA::DLGroupContext::DLGroupContext ( Provider * p )

inline

Standard constructor.

Parameters

p	the provider associated with this context

Definition at line 463 of file qcaprovider.h.

Member Function Documentation

fetchGroup()

virtual void QCA::DLGroupContext::fetchGroup ( DLGroupSet set, bool block )

pure virtual

Attempt to create P, Q, and G values from the specified group set.

If block is true, then this function blocks until completion. Otherwise, this function returns immediately and finished() is emitted when the operation completes.

If an error occurs during generation, then the operation will complete and isNull() will return true.

Parameters

set	the group set to generate the key from
block	whether to block (true) or not (false)

finished

void QCA::DLGroupContext::finished ( )

signal

Emitted when the fetchGroup() operation completes in non-blocking mode.

getResult()

virtual void QCA::DLGroupContext::getResult ( BigInteger * p, BigInteger * q, BigInteger * g ) const

pure virtual

Obtain the result of the operation.

Ensure isNull() returns false before calling this function.

Parameters

p	the P value
q	the Q value
g	the G value

isNull()

virtual bool QCA::DLGroupContext::isNull ( ) const

pure virtual

Returns true if there is a result to obtain.

supportedGroupSets()

virtual QList< DLGroupSet > QCA::DLGroupContext::supportedGroupSets ( ) const

pure virtual

The DLGroupSets supported by this object.
