How to make HMAC SHA256 with SECRET KEY in Android Java Based?

Question

i'm already search for this problem in so many articles and developer environment, but i'd stuck.

I'm searching how to convert String into HMAC-SHA256 in Android Java.

My PHP code is

$data = "Help";
$secret = "A5D!@#";
$key = hash_hmac('sha256', $data, $secret);
echo $key;

// the key is = ede672d9979a804d7a480e511ba556d506d41a1af5959155db208a0416093c7c

I'm really confused about how to convert string to HMAC SHA256 in Android. Is it possible to do in Android (Java Based) ?

Thanks for read this question, hopefully someone can help me. I really appreciate it, if there is someone can help me to solved this problem.

Yes, this is possible in android(java). Is $data = "Help" your string?, I am not sure. If so then, you can follow the code, this is more or less similar to your PHP code.

import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import org.apache.commons.codec.binary.Base64;

    ... ... ...

    String data = "Hello";
    String secret = "A5D!@#";
     

    Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
    SecretKeySpec secret_key = new SecretKeySpec(secret.getBytes(),"HmacSHA256");
    sha256_HMAC.init(secret_key);

    String hash = Base64.encodeBase64String(sha256_HMAC.doFinal(data.getBytes()));
