Constants

const Len = sha256.Size

Len is the length of base addresses

const MaxAddrLen = 255

MaxAddrLen is the maximum allowed length (in bytes) for an address.

Functions

func Compose

func Compose(typ string, subAddresses []Addressable) ([]byte, error)

Compose creates a new address based on sub addresses.

func Derive

func Derive(address []byte, key []byte) []byte

Derive derives a new address from the main `address` and a derivation `key`.

func Hash

func Hash(typ string, key []byte) []byte

Hash creates a new address from address type and key

func LengthPrefix

func LengthPrefix(bz []byte) ([]byte, error)

LengthPrefix prefixes the address bytes with its length, this is used for example for variable-length components in store keys.

func Module

func Module(moduleName string, key []byte) []byte

Module is a specialized version of a composed address for modules. Each module account is constructed from a module name and module account key.

func MustLengthPrefix

func MustLengthPrefix(bz []byte) []byte

MustLengthPrefix is LengthPrefix with panic on error.

Types

type Addressable

type Addressable interface {
	Address() []byte
}
