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.

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

Standard constructor.

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
setthe group set to generate the key from
blockwhether 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
pthe P value
qthe Q value
gthe 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.
