const Sm2KeySize = 32

ref:《SM2椭圆曲线公钥密码算法推荐曲线参数》http://www.oscca.gov.cn/UpFile/2010122214836668.pdf Curve-SM2-P-256: len(P) = 64; len(N) = 64; len(B) = 64; len(Gx) = 32; len(Gy) = 32; so SM2_KEY_SIZE == 32 bytes

Functions ¶

func Base58Decode ¶

func Base58Decode(src []byte) (*big.Int, error)

Decode a big integer from the bytes. Returns an error on corrupt input.

func Base58Encode ¶

func Base58Encode(dst []byte, src *big.Int) []byte

Encode encodes src, appending to dst. Be sure to use the returned new value of dst.

func SM3Hash ¶

func SM3Hash(msg string) string

SM3Hash can generate the SM3 checksum for string.

func SM3HashByte ¶

func SM3HashByte(msg []byte) []byte

like SM3Hash but use byte array.

func VerifySign ¶

func VerifySign(pubKey, sign, hash []byte) bool

Signature Verify

Types ¶

type CorruptInputError ¶

type CorruptInputError int64

func (CorruptInputError) Error ¶

func (e CorruptInputError) Error() string

type Keypair ¶

type Keypair struct {
	PublicKey  []byte
	PrivateKey []byte
}

A set of security credentials you use to prove your identity electronically.

func GenerateKeypair ¶

func GenerateKeypair() *Keypair

Generate New Keypair

func (*Keypair) Sign ¶
