MD5加密简单使用

public class MD5Util {
    public static String encoderPassword(String s) throws NoSuchAlgorithmException, UnsupportedEncodingException {
        MessageDigest md5 = MessageDigest.getInstance("MD5");
        BASE64Encoder base64Encoder = new BASE64Encoder();
        return base64Encoder.encode(md5.digest(s.getBytes("utf-8")));
    }
}

    public static void main(String[] args){
        String s = null;
        try {
            s = MD5Util.encoderPassword("123");
        } catch (Exception e) {
            e.printStackTrace();
        }
        System.out.println(s);
    }
