How to hash a password with SHA-512 in Java?

Question

I\'ve been investigating a bit about Java String encryption techniques and unfortunately I haven\'t find any good tutorial how to hash String with SHA-512 in Java; I read a

Answer 1

import java.nio.charset.StandardCharsets;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import org.apache.commons.codec.binary.Hex;

public String getHashSHA512(String StringToHash, String salt){
        String generatedPassword = null;
        try {
            MessageDigest md = MessageDigest.getInstance("SHA-512");
            md.update(salt.getBytes(StandardCharsets.UTF_8));
            byte[] bytes = md.digest(StringToHash.getBytes(StandardCharsets.UTF_8));
            generatedPassword = Hex.encodeHexString(bytes);
        }
        catch (NoSuchAlgorithmException e){
            e.printStackTrace();
        }
        return generatedPassword;
    }

It's not recommended to use hash functions for passwords though, newer alogrithms like bcrypt, or scrypt exist
