testOneLevelKeyGenAndSign

public void testOneLevelKeyGenAndSign()
                               throws java.lang.Exception

Throws:

java.lang.Exception

testKeyGenAndSign

public void testKeyGenAndSign()
                       throws java.lang.Exception

Throws:

java.lang.Exception

testHssKeyGenAndSign

public void testHssKeyGenAndSign()
                          throws java.lang.Exception

Throws:

java.lang.Exception

testKeyGenAndUsage

public void testKeyGenAndUsage()
                        throws java.lang.Exception

Throws:

testMalformedSignatureUnknownLmOtsType

public void testMalformedSignatureUnknownLmOtsType()
                                            throws java.lang.Exception

RFC 8554 / NIST SP 800-208: HSSPublicKeyParameters.generateLMSContext is the public verify-prep reached from the JCA Signature.verify path and the lightweight HSS verify. A malformed HSS signature whose embedded LM-OTS type code is unknown must be rejected with a clean parse failure, not an unchecked NullPointerException (a remote denial-of-service). See COVERAGE_BUGS_HANDOVER.md finding #17.

Throws:

java.lang.Exception

testReInitClearsTheOtherKey

public void testReInitClearsTheOtherKey()
                                 throws java.lang.Exception

init() used to assign only the key for the mode being set, leaving the other one from a previous init in place: a signer initialised for verification still held the private key and would sign with it, and one initialised for signing still held the public key and would verify. Both keys are now cleared on every init, so using the signer in the mode it was not initialised for is reported rather than silently working off the stale key.

Throws:

java.lang.Exception
