Functions ¶

func Nist256p1 ¶

func Nist256p1() slip10.Curve

Nist256p1 returns a slip10.Curve which implements NIST P-256 (FIPS 186-3, section D.2.3).

func Secp256k1 ¶

func Secp256k1() slip10.Curve

Secp256k1 returns a slip10.Curve which implements secp256k1 (SEC 2, section 2.4.1).

Types ¶

type Curve ¶

type Curve struct {
	elliptic.Curve
}

Curve is an abstract implementation of slip10.Curve based on elliptic.Curve.

func (Curve) HmacKey ¶

func (Curve) HmacKey() []byte

HmacKey must be overridden in any valid implementation.

func (Curve) Name ¶

func (c Curve) Name() string

Name returns the canonical name of the curve.

func (Curve) NewPrivateKey ¶

func (c Curve) NewPrivateKey(buf []byte) (slip10.Key, error)

NewPrivateKey creates a PrivateKey from buf. When buf does not correspond to a valid private key, an error is returned.

type PrivateKey ¶

type PrivateKey struct {
	K     *big.Int
	Curve elliptic.Curve
}

PrivateKey implements slip10.Key and represents a private key for elliptic.Curve.

func (*PrivateKey) Bytes ¶

func (p *PrivateKey) Bytes() []byte

Bytes returns the SLIP-10 serialization of the key.

func (*PrivateKey) ECDSAPrivateKey ¶

func (p *PrivateKey) ECDSAPrivateKey() *ecdsa.PrivateKey

ECDSAPrivateKey returns the corresponding ecdsa.PrivateKey.

func (*PrivateKey) IsPrivate ¶

func (*PrivateKey) IsPrivate() bool

IsPrivate always returns true.

func (*PrivateKey) Public ¶

func (p *PrivateKey) Public() slip10.Key

Public returns the corresponding PublicKey.

func (*PrivateKey) Shift ¶

func (p *PrivateKey) Shift(buf []byte) (slip10.Key, error)

Shift derives a new PrivateKey using the provided additive shift. It returns ErrInvalidKey if the shift leads to an invalid key.

func (*PrivateKey) String ¶

func (p *PrivateKey) String() string

type PublicKey ¶

type PublicKey struct {
	X, Y  *big.Int
	Curve elliptic.Curve
}

PublicKey implements slip10.Key and represents a public key for elliptic.Curve.

func (*PublicKey) Bytes ¶

func (p *PublicKey) Bytes() []byte

Bytes returns the SLIP-10 serialization of the key.

func (*PublicKey) ECDSAPublicKey ¶

func (p *PublicKey) ECDSAPublicKey() *ecdsa.PublicKey

ECDSAPublicKey returns the corresponding ecdsa.PublicKey.

func (*PublicKey) IsPrivate ¶

func (*PublicKey) IsPrivate() bool

IsPrivate always returns false.

func (*PublicKey) Public ¶

func (p *PublicKey) Public() slip10.Key

Public returns a reference to itself.

func (*PublicKey) Shift ¶

func (p *PublicKey) Shift(bytes []byte) (slip10.Key, error)

Shift derives a new PublicKey using the provided additive shift. It returns ErrInvalidKey if the shift leads to an invalid key.

func (*PublicKey) String ¶

func (p *PublicKey) String() string
