Types ¶
type Content ¶
Content represents the data that is stored and verified by the tree. A type that implements this interface can be used as an item in the tree.
type HashContent ¶
HashContent Content For metaID
func (HashContent) CalculateHash ¶
func (t HashContent) CalculateHash() []byte
CalculateHash function to calculate hash
func (HashContent) Equals ¶
func (t HashContent) Equals(other Content) bool
Equals function to compare other Content
type MerkleTree ¶
MerkleTree is the container for the tree. It holds a pointer to the root of the tree, a list of pointers to the leaf nodes, and the merkle root.
func NewTree ¶
func NewTree(cs []Content) (*MerkleTree, error)
NewTree creates a new Merkle Tree using the content cs.
func (*MerkleTree) MerkleRoot ¶
func (m *MerkleTree) MerkleRoot() []byte
MerkleRoot returns the unverified Merkle Root (hash of the root node) of the tree.
func (*MerkleTree) RebuildTree ¶
func (m *MerkleTree) RebuildTree() error
RebuildTree is a helper function that will rebuild the tree reusing only the content that it holds in the leaves.
func (*MerkleTree) RebuildTreeWith ¶
func (m *MerkleTree) RebuildTreeWith(cs []Content) error
RebuildTreeWith replaces the content of the tree and does a complete rebuild; while the root of the tree will be replaced the MerkleTree completely survives this operation. Returns an error if the list of content cs contains no entries.
func (*MerkleTree) String ¶
func (m *MerkleTree) String() string
String returns a string representation of the tree. Only leaf nodes are included in the output.
func (*MerkleTree) VerifyContent ¶
func (m *MerkleTree) VerifyContent(expectedMerkleRoot []byte, content Content) bool
VerifyContent indicates whether a given content is in the tree and the hashes are valid for that content. Returns true if the expected Merkle Root is equivalent to the Merkle root calculated on the critical path for a given content. Returns true if valid and false otherwise.
func (*MerkleTree) VerifyTree ¶
func (m *MerkleTree) VerifyTree() bool
VerifyTree verify tree validates the hashes at each level of the tree and returns true if the resulting hash at the root of the tree matches the resulting root hash; returns false otherwise.
