golang 中的md5 、hmac、sha1算法的简单实现
package main
import (
"crypto/hmac"
"crypto/md5"
"crypto/sha1"
"encoding/hex"
"fmt"
)
func Md5(data string) string {
md5 := md5.New()
md5.Write([]byte(data))
md5Data := md5.Sum([]byte(""))
return hex.EncodeToString(md5Data)
}
func Hmac(key, data string) string {
hmac := hmac.New(md5.New, []byte(key))
hmac.Write([]byte(data))
return hex.EncodeToString(hmac.Sum([]byte("")))
}
func Sha1(data string) string {
sha1 := sha1.New()
sha1.Write([]byte(data))
return hex.EncodeToString(sha1.Sum([]byte("")))
}
func main() {
fmt.Println(Md5("hello"))
fmt.Println(Hmac("key2", "hello"))
fmt.Println(Sha1("hello"))
}
