示例1: init
import org.bouncycastle.crypto.params.KDFFeedbackParameters; //导入方法依赖的package包/类
public void init(DerivationParameters params)
{
if (!(params instanceof KDFFeedbackParameters))
{
throw new IllegalArgumentException("Wrong type of arguments given");
}
KDFFeedbackParameters feedbackParams = (KDFFeedbackParameters)params;
// --- init mac based PRF ---
this.prf.init(new KeyParameter(feedbackParams.getKI()));
// --- set arguments ---
this.fixedInputData = feedbackParams.getFixedInputData();
int r = feedbackParams.getR();
this.ios = new byte[r / 8];
if (feedbackParams.useCounter())
{
// this is more conservative than the spec
BigInteger maxSize = TWO.pow(r).multiply(BigInteger.valueOf(h));
