This example shows how the
method is
used to populate a descriptor with a series of random bytes.
CRandom::GenerateRandomBytesL()
#include <legacyselector.h>
#include <cryptorandomapi.h>
using namespace CryptoSpi;
//Create a pointer to store the factory-generated random implementation object
CRandom* randomImpl = NULL;
//Calling the CreateRandomL() method of the random factory class
//creates a new CRandom object
TRAPD(err, CRandomFactory::CreateRandomL(randomImpl, KRandomUid, NULL));
if(randomImpl && (err == KErrNone))
{
//Create an 8 bit descriptor 50 bytes long with a max length of 50 bytes
TBuf8<50> randomStr(50);
//Passing the 8 bit descriptor to the CRandom::GenerateRandomBytesL()
//method fills it with random bytes. If there is no memory available
//or any problems occur, the method may leave.
randomImpl->GenerateRandomBytesL(randomStr);
}
//Destroy the random implementation object
delete randomImpl;
randomImpl = NULL;
