Class SampleNttTest

java.lang.Object

junit.framework.Assert

junit.framework.TestCase

org.bouncycastle.crypto.kems.mlkem.SampleNttTest

All Implemented Interfaces:

junit.framework.Test

public class SampleNttTest
extends junit.framework.TestCase

Checks MLKEMIndCpa.sampleNtt against a direct transcription of FIPS 203 Algorithm 7 (SampleNTT). Real seeds needing more than one extra XOF block occur with probability about 2^-105 per entry, so those cases use a scripted stream.
