Functions

func EcdsaSign

func EcdsaSign(priv *ecdsa.PrivateKey, text []byte) (string, error)

EcdsaSign The encryption result of the text signature is returned. The result is the serialization and splicing of the digital certificate R and s, and then converted into string with hex

func EcdsaSignDecode

func EcdsaSignDecode(sign string) (rint, sint big.Int, err error)

EcdsaSignDecode r, s String parsing

func EcdsaSignEncode

func EcdsaSignEncode(r, s *big.Int) (string, error)

EcdsaSignEncode r, s Convert to string

func EcdsaVerify

func EcdsaVerify(text []byte, sign string, pubKey *ecdsa.PublicKey) (bool, error)

EcdsaVerify Verify whether the text content is consistent with the signature. Use the public key to verify the signature and text content
