Method Summary

Modifier and Type	Method and Description
void	testConstructor()
void	testSignatureParsingSHA256()
void	testSignatureParsingSHA512()
void	testSignatureWrongSizeRejected() An XMSS signature is a (4 + n + (len + h) * n)-byte string (RFC 8391 sec. 4.1.8), so a signature carrying trailing data - or a truncated one - is not a signature for these parameters.
void	testVerifyRejectsWrongSize() The parse-level check above has to reach verification: a signature with bytes appended, or one cut short, must answer false rather than verify (github #2408).

testSignatureParsingSHA256

public void testSignatureParsingSHA256()

testSignatureParsingSHA512

public void testSignatureParsingSHA512()

testSignatureWrongSizeRejected

public void testSignatureWrongSizeRejected()

An XMSS signature is a (4 + n + (len + h) * n)-byte string (RFC 8391 sec. 4.1.8), so a signature carrying trailing data - or a truncated one - is not a signature for these parameters. XMSSMTSignature has always checked this way (github #2408).

testVerifyRejectsWrongSize

public void testVerifyRejectsWrongSize()

The parse-level check above has to reach verification: a signature with bytes appended, or one cut short, must answer false rather than verify (github #2408).
