Variables

var Hasher = &TreeHasher{Hash: crypto.SHA256}

Hasher is a SHA256 based TreeHasher.

Types

type TreeHasher

type TreeHasher struct {
	crypto.Hash
}

TreeHasher implements the RFC6962 tree hashing algorithm.

func (TreeHasher) HashChildren

func (t TreeHasher) HashChildren(l, r []byte) []byte

HashChildren returns the inner Merkle tree node hash of the the two child nodes l and r. The hashed structure is NodeHashPrefix||l||r.

func (TreeHasher) HashEmpty

func (t TreeHasher) HashEmpty() []byte

HashEmpty returns the hash of an empty element for the tree

func (TreeHasher) HashLeaf

func (t TreeHasher) HashLeaf(leaf []byte) []byte

HashLeaf returns the Merkle tree leaf hash of the data passed in through leaf. The data in leaf is prefixed by the LeafHashPrefix.
