## 特性
- 根据GoogleAuthenticator demo中抽离出来的关键部分算法，可以和https://github.com/google/google-authenticator-android 官方demo做下对比
- 模仿了现在主流手机宝令翻牌的效果

## 原理说明
- demo中需要一个secret key字母表在ABCDEFGHIJKLMNOPQRSTUVWXYZ234567之间，需要同服务端相同
- 项目中时间步长为30s,算法还需传递一个当前时间，必须保证这个时间的准确性，所以必须和服务器时间相同(可以有一定的误差，不能太大)
- 最后生成一个6位的认证令牌

## Getting started
Add it in your root build.gradle at the end of repositories:
 ```java
allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}
 ```
 Add the dependency
  ```java
 dependencies {
        compile 'com.github.Yuphee:GoogleTotpAuth:VERSION_CODE'
}
 ```
 replace VERSION_CODE with real version name such as released in [Here](https://github.com/Yuphee/GoogleTotpAuth/releases)
 
 ### notice
 
 Both have to write, or else can not be loaded successfully.

## 使用方法
-seed初始化
 ```java
public class MApplication extends Application{

    private static MApplication instance = null;

    public static MApplication getInstance() {
        if (null == instance) {
            instance = new MApplication();
        }
        return instance;
    }

    public MApplication() {

    }

    @Override
    public void onCreate() {
        super.onCreate();
        instance = this;
        SPUtils.init(this);
        TotpUtil.init("FZ6S5VB64HVSYLJN");// 初始化SEED
    }
}
```
-生成令牌
 ```java
 
 TotpUtil.generate();

 ```
 -动画相关的逻辑参考MainActivity
