func Sign
func Sign(rand io.Reader, priv *PrivateKey, hash []byte) (r, s *big.Int, err error)
Sign signs an arbitrary length hash (which should be the result of hashing a larger message) using the private key, priv. It returns the signature as a pair of integers. The security of the private key depends on the entropy of rand.
func Verify
func Verify(pub *PublicKey, hash []byte, r, s *big.Int) bool
Verify verifies the signature in r, s of hash using the public key, pub. It returns true iff the signature is valid.
type PrivateKey
type PrivateKey struct { PublicKey D *big.Int }
PrivateKey represents a ECDSA private key.
func GenerateKey
func GenerateKey(c elliptic.Curve, rand io.Reader) (priv *PrivateKey, err error)
GenerateKey generates a public&private key pair.
type PublicKey
type PublicKey struct { elliptic.Curve X, Y *big.Int }
PublicKey represents an ECDSA public key.
