This example shows how the CRandom::GenerateRandomBytesL() method is used to populate a descriptor with a series of random bytes.
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;
