func Encrypt

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

func EthereumChecksumAddress

func EthereumChecksumAddress(s string) string

EthereumChecksumAddress is a simple utility function to ensure all ethereum addresses used in zeta are checksumed this expects a hex encoded string.

func EthereumIsValidAddress

func EthereumIsValidAddress(s string) bool

EthereumIsValidAddress returns whether the given string is a valid ethereum address.

func Hash

func Hash(key []byte) []byte

func HashBytesBuffer

func HashBytesBuffer(key bytes.Buffer) []byte

func HashStrToHex

func HashStrToHex(s string) string

HashStrToHex hash a string returns a hex encoded string of the result.

func HashToHex

func HashToHex(data []byte) string

HashToHex hash the input bytes and returns a hex encoded string of the result.

func IntToHex

func IntToHex(num uint64) []byte

func IsValidZetaID

func IsValidZetaID(id string) bool

func IsValidZetaPubKey

func IsValidZetaPubKey(pkey string) bool

func NewNonce

func NewNonce() uint64

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 the 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.

Types

	// contains filtered or unexported fields
}

func NewPublicKey

func NewPublicKey(hex string, bytes []byte) PublicKey

func (PublicKey) Bytes
