Method Detail

getHash

public byte[] getHash(DigestCalculator digestCalculator)

Compute a hash over the whole partialHashTree: - Concatenate all the hashes contained in the partial hash tree; - Generate a hash over the concatenated hashes, using a provided DigestCalculator.

Parameters:

digestCalculator - the DigestCalculator to use in order to generate the hash

Returns:

a hash value that is representative of the whole partial hash tree.

verifyContainsHash

public void verifyContainsHash(byte[] hash)
                        throws PartialHashTreeVerificationException

Checks whether a PartialHashtree (RFC4998) contains a given hash.

Parameters:

hash - the hash to check

Throws:

PartialHashTreeVerificationException - if the hash is not present in the PartialHashtree

containsHash

public boolean containsHash(byte[] hash)

Checks whether a PartialHashtree (RFC4998) contains a given hash.

Parameters:

hash - the hash to check

Returns:

true if the hash is present within the PartialHashtree's set of values, false otherwise.
