GenerateRandomBytesL(TDes8 &, TRequestStatus &)

void	GenerateRandomBytesL	(	TDes8 &	aDest,
			TRequestStatus &	aStatus
		)	[pure virtual]

Implementations of this method should fill the passed buffer with the generated pseudo-random data up to the current length, discarding any current contents. The implementations should leave with KErrNotSecure when the generated random data is not secure enough.

leave: KErrNotSecure Random data generated is not secure enough for crytographic operations otherwise, leaves with any other system wide error code.

Parameters

TDes8 & aDest	The buffer to fill with random data
TRequestStatus & aStatus	The argument to carry the asynchonous request completion status to notify the client when buffer is filled with random data.
