Why in Android Java and PHP HMAC SHA 256 results are different?

Question

PHP

Can't figure out why:
Android Java:

private hash_hmac(String str, String secret){
    Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
    SecretKeySpec secretKey = new SecretKeySpec(secret.getBytes("UTF-8"), "HmacSHA256");
    sha256_HMAC.init(secretKey);
    String hash1 = Base64.encodeToString(sha256_HMAC.doFinal(str.getBytes("UTF-8")), 0);
        return hash1;
    }

Variables:

str = "eyJoYXNoIjoic29tZVJlcUhhc2hTdHIiLCJhbnN3ZXIiOnRydWV9"
    secret = "AusVwlqhJY4YvuCIdotMpduVWWQdiVnl"

Result:
UuJhaD7sjLXUPN01JJWEcObIwDdLXHturBdSZFxKPxI=
and in PHP:

$str=base64_encode('eyJoYXNoIjoic29tZVJlcUhhc2hTdHIiLCJhbnN3ZXIiOnRydWV9');
    $key='AusVwlqhJY4YvuCIdotMpduVWWQdiVnl';
    print(base64_encode(hash_hmac('sha256', $str, $key,true)));

Result:
AWFG4WXHtOToeN8d4J4Lt67u8VVa35AxBfIEsg31DhU=
Different results. I can't figure out why. At the same time, in desktop JAVA it coincides with PHP, but not in Android.

Answer 1

According to Stackoverflow , there is a difference in the string handler on Android in Java, in order to work the same way as on the desktop, you need to add the Base64.NO_WRAP key

Base64.encode("foobar".getBytes(), Base64.NO_WRAP);
