org.bouncycastle.pqc.crypto.test.LMSPromotionCompatibilityTest

All Implemented Interfaces:

junit.framework.Test

public class LMSPromotionCompatibilityTest
extends junit.framework.TestCase

The LMS/HSS implementation under org.bouncycastle.crypto is a copy of the deprecated org.bouncycastle.pqc.crypto.lms one, so the two must agree byte for byte on every encoding and each must verify what the other signed. This test pins that down over the whole parameter-set matrix, and is the guard against the copy drifting from the original while both ship.

Method Summary

Modifier and Type	Method and Description
void	testHSSKeysAndSignaturesMatchAcrossImplementations() The same for the HSS multi-tree variant, whose private key encoding carries the per-level index state - the part most likely to drift.
void	testLMSKeysAndSignaturesMatchAcrossImplementations() The same seed drives both implementations, so a matching set of keys must come out with identical X.509 / PKCS#8 encodings, and each side must verify the other's signature.
void	testStreamingMatchesOneShot() The promoted signers implement org.bouncycastle.crypto.Signer rather than the pqc MessageSigner, so the streaming path must produce exactly what the one-shot call does.
