Method Detail

computeRootHash

public byte[] computeRootHash(DigestCalculator digCalc,
                              org.bouncycastle.asn1.tsp.PartialHashtree[] nodes)
Calculate the root hash of the Merkle tree from the partial hash-tree nodes.

Parameters:
digCalc - the digest calculator to use.
nodes - the partial hash-trees forming the basis of the Merkle tree.
Returns:
the root hash of the Merkle tree.
