public class XMSSPrivateKeyEncodingTest
extends junit.framework.TestCase

PKCS#8 PrivateKeyInfo round-trip coverage for XMSS / XMSS^MT (github #2176). Every standard (RFC 8391 / SP 800-208) parameter set is now encoded in the RFC 9802 form (id-alg-xmss-hashsig / id-alg-xmssmt-hashsig) that the matching SubjectPublicKeyInfo uses, so a keypair's private and public halves share one algorithm OID and a private key round-trips to its exact parameter set.

Before the fix, the SP 800-208 sets either threw during encoding (SHAKE256-LEN, unknown to the legacy tree-digest table) or silently round-tripped to a different set (SHA-256/192, which shares id-sha256 with the RFC 8391 SHA-256/256 set and lost n=24), and every set's private key carried the legacy PQCObjectIdentifiers.xmss(_mt) OID rather than the public key's RFC 9802 OID.
