Functions

func FromECDSAPub

func FromECDSAPub(pub *ecdsa.PublicKey) []byte

func NewPublicKeyCoords

func NewPublicKeyCoords(x, y *big.Int) (*ecdsa.PublicKey, error)

PublicKeyFromCoordinates serializes an (X, Y) coordinate pair into a public key. Returns nil if X or Y are nil.

func S256

func S256() elliptic.Curve

S256 returns an instance of the secp256k1 curve.

func ToECDSA

func ToECDSA(d []byte) (*ecdsa.PrivateKey, error)

ToECDSA creates a private key with the given D value.

func UnmarshalPubkey

func UnmarshalPubkey(pub []byte) (*ecdsa.PublicKey, error)

UnmarshalPubkey converts bytes to a secp256k1 public key.
