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

QCA::DLGroupContext::DLGroupContext ( Provider p  )  [inline]

Standard constructor.

Parameters:
p the provider associated with this context


Member Function Documentation

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)

void QCA::DLGroupContext::finished (  )  [signal]

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

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

virtual bool QCA::DLGroupContext::isNull (  )  const [pure virtual]

Returns true if there is a result to obtain.

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

The DLGroupSets supported by this object.
