Method Details

initList

void initList(List<Integer> sigalg)

Initialize this instance from a signalled algo list.

Parameters:

sigalg - signalled algorithm list.

initDs

List<Integer> initDs(RRset dsRRset,
 int favoriteDsAlgorithm)

Initialize algo needs structure, set algos from rrset as needed.

Parameters:

dsRRset - algorithms from this RRset are necessary.

favoriteDsAlgorithm - filter to use only this DS algo.

Returns:

List of signalled algorithms.

setSecure

boolean setSecure(int algo)

Mark this algorithm as a success (SecurityStatus.SECURE), and see if we are done.

Parameters:

algo - : the algorithm processed to be secure.

Returns:

if true, processing has finished successfully, we are satisfied.

setBogus

void setBogus(int algo)

Mark this algorithm a failure (SecurityStatus.BOGUS). It can later be overridden by a success for this algorithm (with a different signature).

Parameters:

algo - the algorithm processed to be bogus.

missing

int missing()

See how many algorithms are missing (not bogus or secure, but not processed)

Returns:

number of algorithms missing after processing.
