Generate public key and private key,the public key is point compress

// BHGeneratePointCompressKey used to product publicKey and privateKey.
// The publicKey is ponit compressed
func BHGeneratePointCompressKey() (pubKey string, priKey string, err error)

Generate public key and private key

// BHGenerateKey used to product publicKey and privateKey
func BHGenerateKey() (pubKey string, priKey string, err error)

sm2 sign

// BHSign used to sign src,priKey is hex string.return r/s bytes
// If userID be assigned nil,which will use default value,default value is 1234567812345678 bytes
func BHSign(priKey string, userID []byte, src []byte) ([]byte, error)

sm2 sign with asn1

// BHSignX used to sign src,priKey is hex string.return asn.1 format bytes
// If userID be assigned nil,which will use default value,default value is 1234567812345678 bytes
func BHSignX(priKey string, userID []byte, src []byte) ([]byte, error)

sm2 verify use point compress pubkey

// BHVerifyWithPointCompress used to verify src and sign,the pubKey is point compress,the sign is r/s bytes
// If userID be assigned nil,which will use default value,default value is 1234567812345678 bytes
func BHVerifyWithPointCompress(pubKey string, userID []byte, src []byte, sign []byte) (pass bool, err error)

sm2 verify use point compress pubkey,the sign is asn1 format

// BHVerifyWithPointCompressX used to verify src and sign,the pubKey is point compress,the sign is asn.1 format bytes
// If userID be assigned nil,which will use default value,default value is 1234567812345678 bytes
func BHVerifyWithPointCompressX(pubKey string, userID []byte, src []byte, sign []byte) (pass bool, err error)

sm2 verify

// BHVerify function is similar with VerifyWithPointCompress,the pubKey is unCompress,the sign is r/s bytes
// If userID be assigned nil,which will use default value,default value is 1234567812345678 bytes
func BHVerify(pubKey string, userID []byte, src []byte, sign []byte) (pass bool, err error))

sm2 verify,the sign is asn1 format
