Functions

func GenPublicKey

func GenPublicKey(seed, pubSeed []byte, adrs *Address) []byte

Computes the public key that corresponds to the expanded seed.

func PkFromSig

func PkFromSig(sig, msg, pubSeed []byte, adrs *Address) []byte

Generates a public key from the given signature

func Sign

func Sign(msg, seed, pubSeed []byte, adrs *Address) []byte

Signs message msg using the private key generated using the given seed.

func Verify

func Verify(pk, sig, msg, pubSeed []byte, adrs *Address) bool

Verifies the given signature on the given message.

Types

type Address

type Address struct {
	// contains filtered or unexported fields
}

Describes a hash address, i.e. where a hash is calculated. It is used to randomize each hash function call.

func (*Address) SetLayer

func (a *Address) SetLayer(l uint32)

func (*Address) SetOTS

func (a *Address) SetOTS(o uint32)

func (*Address) SetTree

func (a *Address) SetTree(t uint64)

func (*Address) SetType

func (a *Address) SetType(t uint32)

func (*Address) ToBytes

func (a *Address) ToBytes() []byte
