Overview ¶
Package ecdsa implements the Elliptic Curve Digital Signature Algorithm, as defined in FIPS 186-3.
This implementation derives the nonce from an AES-CTR CSPRNG keyed by ChopMD(256, SHA2-512(priv.D || entropy || hash)). The CSPRNG key is IRO by a result of Coron; the AES-CTR stream is IRO under standard assumptions.

Functions ¶
func GenerateKeyBySeed ¶
GenerateKey generates a public and private key pair.
func MarshalECDSASignature ¶
use DER-encoded ASN.1 octet standard to represent the signature 与比特币算法一样，基于DER-encoded ASN.1 octet标准，来表达使用椭圆曲线签名算法返回的结果
func SignV2ECDSA ¶
func SignV2ECDSA(k *ecdsa.PrivateKey, msg []byte) (signature []byte, err error)
func UnmarshalECDSASignature ¶
