Overview ¶

Package ECDSA implements soominhyunwoo-SDK compatible ECDSA public and private key. The keys can be serialized.

- func GenPrivKey(curve elliptic.Curve) (PrivKey, error)
type PubKey

Types ¶

type PrivKey ¶

type PrivKey struct {
	ecdsa.PrivateKey
}

func GenPrivKey ¶

func GenPrivKey(curve elliptic.Curve) (PrivKey, error)

GenPrivKey generates a new secp256r1 private key. It uses operating system randomness.

func (*PrivKey) Bytes ¶

func (sk *PrivKey) Bytes() []byte

Bytes serialize the private key using big-endian.

func (*PrivKey) MarshalTo ¶

func (sk *PrivKey) MarshalTo(dAtA []byte) (int, error)

MarshalTo implements proto.Marshaler interface.

func (*PrivKey) PubKey ¶

func (sk *PrivKey) PubKey() PubKey

PubKey returns ECDSA public key associated with this private key.

func (*PrivKey) Sign ¶

func (sk *PrivKey) Sign(msg []byte) ([]byte, error)

Sign hashes and signs the message usign ECDSA. Implements SDK PrivKey interface.

func (*PrivKey) String ¶

func (sk *PrivKey) String(name string) string

String returns a string representation of the public key based on the curveName.

func (*PrivKey) Unmarshal ¶

func (sk *PrivKey) Unmarshal(bz []byte, curve elliptic.Curve, expectedSize int) error

Unmarshal implements proto.Marshaler interface.

type PubKey ¶

type PubKey struct {
	ecdsa.PublicKey
	// contains filtered or unexported fields
}

func (*PubKey) Address ¶

func (pk *PubKey) Address(protoName string) tmcrypto.Address

Address gets the address associated with a pubkey. If no address exists, it returns a newly created ADR-28 address for ECDSA keys. protoName is a concrete proto structure id.

func (*PubKey) Bytes ¶

func (pk *PubKey) Bytes() []byte

Bytes returns the byte representation of the public key using a compressed form specified in section 4.3.6 of ANSI X9.62 with first byte being the curve type.

func (*PubKey) MarshalTo ¶

func (pk *PubKey) MarshalTo(dAtA []byte) (int, error)

MarshalTo implements proto.Marshaler interface.

func (*PubKey) String ¶

func (pk *PubKey) String(curveName string) string

String returns a string representation of the public key based on the curveName.

func (*PubKey) Unmarshal ¶

func (pk *PubKey) Unmarshal(bz []byte, curve elliptic.Curve, expectedSize int) error

Unmarshal implements proto.Marshaler interface.

func (*PubKey) VerifySignature ¶

func (pk *PubKey) VerifySignature(msg []byte, sig []byte) bool

VerifySignature checks if sig is a valid ECDSA signature for msg.
