func Md5String

func Md5String(str string) string

生成32位md5字符串 It takes a string, creates a new MD5 hash, writes the string to the hash, and then returns the hexadecimal representation of the hash

func NullUnPadding

func NullUnPadding(in []byte) []byte

It removes all the null bytes from the end of the input byte array

func SigRSV

func SigRSV(isig interface{}) ([32]byte, [32]byte, uint8)

SigRSV signatures R S V returned as arrays

func SigToPub

func SigToPub(hash, sig []byte) (*ecdsa.PublicKey, error)

SigToPub returns the public key that created the given signature.

func SignBuyOrder

func SignBuyOrder(hash string, key string) map[string]interface{}

func SignMint

func SignMint(address string, tokenId int64, key string) map[string]interface{}

It takes the address of the owner, the tokenId of the token to be minted, and the private key of the owner, and returns the signature of the minting transaction

func SignOrder

func SignOrder(data []byte) string

discard & 弃用

func SignTest

func SignTest()

It takes a message, hashes it, signs the hash with a private key, and returns the signature

func VerifySig

func VerifySig(from string, sigHex string, msg []byte) bool

It takes a message, a signature, and a public key, and returns true if the signature is valid for the message under the public key

func ZeroPadding

func ZeroPadding(in []byte) []byte

If the length of the input is a multiple of 8, return the input, otherwise return the input with enough zero bytes appended to make the length a multiple of 8
