Hash

Hash Repo

type HashRepo interface {
	// checksum string once
	Sum(s string) string
	// checksum bytes once
	SumBytes(bs []byte) string
	// checksum string more times
	SumTimes(s string, times uint) string
	// checksum bytes more times
	SumBytesTimes(bs []byte, times uint) string
}

Usage

md5

	s :=  hash.NewHashRepo(crypto.MD5).Sum("test")
	fmt.Println(s)

SHA1

	s :=  hash.NewHashRepo(crypto.SHA1).Sum("test")
	fmt.Println(s)

support hash

• md5
• sha1
• sha224
• sha256
• sha384
• sha512
