Functions

func VerifySignature

func VerifySignature(key *Key, contentSigned []byte, signature []byte) error

Types

type Key

type Key struct {
	Key       []byte
	ChainCode []byte
}

func DeriveForPath

func DeriveForPath(path string, seed []byte) (*Key, error)

DeriveForPath derives key for a path in BIP-44 format and a seed. Ed25119 derivation operated on hardened keys only.

func Generate

func Generate() *Key

func NewMasterKey

func NewMasterKey(seed []byte) (*Key, error)

NewMasterKey generates a new master key from seed.

func (*Key) Derive

func (k *Key) Derive(i uint32) (*Key, error)

func (*Key) PublicKey

func (k *Key) PublicKey() ([]byte, error)

PublicKey returns public key for a derived private key.

func (*Key) PublicKeyMultibase

func (k *Key) PublicKeyMultibase() (string, error)

PublicKeyString returns Base64URL encoded representation of public key

func (*Key) RawSeed

func (k *Key) RawSeed() [32]byte

RawSeed returns raw seed bytes

func (*Key) Sign

func (k *Key) Sign(content []byte) ([]byte, error)

Signs somethign with this key
