Method Detail

computeRootHash

byte[] computeRootHash(org.bouncycastle.operator.DigestCalculator digCalc,
                       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.
