Overview ¶
Package hash contains wrappers for Neo hashing algorithms.
It also implements Merkle tree.

Functions ¶
func CalcMerkleRoot ¶ added in v0.92.0
CalcMerkleRoot calculates the Merkle root hash value for the given slice of hashes. It doesn't create a full MerkleTree structure and it uses the given slice as a scratchpad, so it will destroy its contents in the process. But it's much more memory efficient if you only need a root hash value. While NewMerkleTree would make 3*N allocations for N hashes, this function will only make 4.
func Checksum ¶
Checksum returns the checksum for a given piece of data using DoubleSha256 as the hash algorithm. It returns the first 4 bytes of the resulting slice.
func DoubleSha256 ¶
DoubleSha256 performs sha256 twice on the given data.
func NetSha256 ¶ added in v0.94.1
NetSha256 calculates a network-specific hash of the Hashable item that can then be signed/verified.
Types ¶
type Hashable ¶ added in v0.94.1
Hashable represents an object which can be hashed. Usually, these objects are io.Serializable and signable. They tend to cache the hash inside for effectiveness, providing this accessor method. Anything that can be identified with a hash can then be signed and verified.
type MerkleTree ¶
type MerkleTree struct {
// contains filtered or unexported fields
}
MerkleTree implementation.
func NewMerkleTree ¶
func NewMerkleTree(hashes []util.Uint256) (*MerkleTree, error)
NewMerkleTree returns a new MerkleTree object.
func (*MerkleTree) Root ¶
func (t *MerkleTree) Root() util.Uint256
Root returns the computed root hash of the MerkleTree.
type MerkleTreeNode ¶
type MerkleTreeNode struct {
// contains filtered or unexported fields
}
MerkleTreeNode represents a node in the MerkleTree.
func (*MerkleTreeNode) IsLeaf ¶
func (n *MerkleTreeNode) IsLeaf() bool
IsLeaf returns whether this node is a leaf node or not.
func (*MerkleTreeNode) IsRoot ¶
func (n *MerkleTreeNode) IsRoot() bool
IsRoot returns whether this node is a root node or not.
