Java - Encrypt a String

import java.security.MessageDigest;

public class EncryptExample {
    public static void main(String[] args) {
        String password = "secret";
        String algorithm = "SHA";

        byte[] plainText = password.getBytes();

        MessageDigest md = null;

        try {
            md = MessageDigest.getInstance(algorithm);
        } catch (Exception e) {
            e.printStackTrace();
        }

        md.reset();
        md.update(plainText);
        byte[] encodedPassword = md.digest();

        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < encodedPassword.length; i++) {
            if ((encodedPassword[i] & 0xff) < 0x10) {
                sb.append("0");
            }
