Golangはsha 256暗号化を実現

まずPHPコードを貼り付けます.

$string = "1234";
$key = "abcd";
$signature = hash_hmac('sha256', $string, $key);

そしてGolang:

package main

import (
	"crypto/hmac"
	"crypto/sha256"
	"encoding/hex"
	"fmt"
)

func main() {
	s := []byte("1234")
	key := []byte("abcd")
	m := hmac.New(sha256.New, key )
	m.Write( s )
	signature := hex.EncodeToString(m.Sum(nil))
	fmt.Print(signature + "
\r")
}
