Exported Values

	 func GenerateKey(c elliptic.Curve, rand io.Reader) (*PrivateKey, error)
		GenerateKey generates a public and private key pair.
	 func Sign(rand io.Reader, priv *PrivateKey, hash []byte) (r, s *big.Int, err error)
		Sign signs a hash (which should be the result of hashing a larger message)
		using the private key, priv. If the hash is longer than the bit-length of the
		private key's curve order, the hash will be truncated to that length. It
		returns the signature as a pair of integers. The security of the private key
		depends on the entropy of rand.
	 func SignASN1(rand io.Reader, priv *PrivateKey, hash []byte) ([]byte, error)
		SignASN1 signs a hash (which should be the result of hashing a larger message)
		using the private key, priv. If the hash is longer than the bit-length of the
		private key's curve order, the hash will be truncated to that length. It
		returns the ASN.1 encoded signature. The security of the private key
		depends on the entropy of rand.
	 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. Its
		return value records whether the signature is valid.
	 func VerifyASN1(pub *PublicKey, hash, sig []byte) bool
		VerifyASN1 verifies the ASN.1 encoded signature, sig, of hash using the
		public key, pub. Its return value records whether the signature is valid.
