Functions

func CountZeros

func CountZeros(d []byte) byte

func Decrypt

func Decrypt(data []byte, passphrase string) ([]byte, error)

func Encrypt

func Encrypt(data []byte, passphrase string) ([]byte, error)

func Hash

func Hash(key []byte) []byte

func IntToHex

func IntToHex(num uint64) []byte

func PoW

func PoW(blockHash string, txID string, difficulty uint, hashFunction string) (uint64, []byte, error)

PoW calculates proof of work given block hash, transaction hash, target difficulty and a hash function. returns the nonce, the hash and th error if any.

func RandomHash

func RandomHash() string

func Verify

func Verify(blockHash string, tid string, nonce uint64, hashFuncion string, difficulty uint) (bool, byte)

Verify checks that the hash with the given nonce results in the target difficulty.
