Metode cek email menggunakan Ptern dan Password menggunakan Encription MD5

cek email dengan menggunakan patern

private boolean cekemail(String emailInput) {
    String EMAIL_PATTERN = "^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"

            + "[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
    Pattern pattern = Pattern.compile(EMAIL_PATTERN);

    Matcher matcher = pattern.matcher(emailInput);

    return matcher.matches();}

dan encription MD5 yang mmbaut password lebih aman dari mesin perhitungan logaitma.

public static String convertPassMd5(String pass) {
    String password = null;    MessageDigest mdEnc;    try {
        mdEnc = MessageDigest.getInstance("MD5");

        mdEnc.update(pass.getBytes(), 0, pass.length());

        pass = new BigInteger(1, mdEnc.digest()).toString(16);

        while (pass.length() < 32) {
            pass = "0" + pass;        }
        password = pass;    } catch (NoSuchAlgorithmException e1) {
        e1.printStackTrace();

//            Logger.getLogger(Signup.class.getName()).log(Level.SEVERE, null, e1);//            if encoding Exception null//        } catch (UnsupportedEncodingException e1) {//            Logger.getLogger(Signup.class.getName()).log(Level.SEVERE, null, e1);

    }
    return password;}
