MessageDigest to CryptoJS digest byteBuffer SHA512 - postman

Question

i try to digest an array of bytes with SHA512
Java:
MessageDigest sha512 = MessageDigest.getInstance("SHA-512");
System.out.println("sha512: "+Arrays.toString(sha512.digest(buffer.array())));
this sample computes with input:
[18, 52, 49, 114, -101, -17, 46, -74, -108, 84, 7, -37, -51, -87, -75, 123, 113, 71, -52, 109, -69, 6, 46, 19, -108, 100, -33, 14, 74, 122, -126, -103, 81, -93]
this output:
[-6, -75, -91, -50, 3, 5, -78, -74, -63, -33, -103, 24, -18, 39, -45, -22, 30, -10, 58, -7, -2, -28, 77, 43, -78, 58, 123, -101, -12, 22, 63, 16, -56, -17, 58, 13, -26, 61, -45, -22, 100, 121, -118, -86, 53, 115, -42, 90, -70, 67, -61, 100, 54, -46, -113, -119, -95, 27, 23, -95, -76, 51, 52, 99]
how can i get the same result using CryptoJS on postman?
thanks-

Answer 1

Here ist the java code, that i want translate to javaScript usung CryptoJS into postman as pre-script to compute a SHA512 hash:
package hashtest;
import java.nio.ByteBuffer;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import com.google.common.io.BaseEncoding;
public class SpinHash
{
private static byte[] applyChallenge(byte[] encrypted, byte[] challenge) throws NoSuchAlgorithmException {
byte[] KEY_CHALLENGE_SEPARATOR = "".getBytes();
MessageDigest sha512 = MessageDigest.getInstance("SHA-512");
ByteBuffer buffer = ByteBuffer.allocate(encrypted.length + challenge.length + KEY_CHALLENGE_SEPARATOR.length);
buffer.put(encrypted);
buffer.put(KEY_CHALLENGE_SEPARATOR);
buffer.put(challenge);
buffer.compact();
return sha512.digest(buffer.array());
}
private static String returnHashPin(String spin, String challenge) throws NoSuchAlgorithmException
{
BaseEncoding BASE16 = BaseEncoding.base16();
byte[] _challenge = BASE16.decode(challenge.toUpperCase());
byte[] _SPIN = BASE16.decode(spin.toUpperCase());
byte[] answer;
answer = applyChallenge(_SPIN, _challenge);
return BASE16.encode(answer).toUpperCase();
}
public static void main(String[] args) throws NoSuchAlgorithmException
{
System.out.println( "Hash-Wert: " + returnHashPin("1234","089C25A81BA2B17601FB89A47CEE561737AA41055AFE88766883CA9C9E7545F5") );
}
}
