使用jdk自帶的base64編碼實現MD5加密

public static String encodePWDByMd5(String pwd) throws NoSuchAlgorithmException, UnsupportedEncodingException {
        MessageDigest md5 = MessageDigest.getInstance("MD5");
        BASE64Encoder base64en=new BASE64Encoder();
        String encode = base64en.encode(md5.digest(pwd.getBytes("utf-8"
 
)));
        return encode;
    }
