## 如何使用

安装

```bash
>pip install text_blind_watermark
```


### 把信息不可见地嵌入到文本中

```python
from text_blind_watermark import TextBlindWatermarkThin

# 密码
password = '20190808'
# 要嵌入的信息
watermark = 'github.com/guofei9987'
text_blind_wm = TextBlindWatermarkThin(password=password)

wm = text_blind_wm.embed(watermark=watermark)
# This is example，you can put wm everywhere
text_embed = '这句话中有盲' + wm + '水印，你能提取出来吗？'
print(text_embed)
```

这句话中有盲水印，你能提取出来吗？


### 从文本中提取不可见的信息

```python
text_blind_wm_new = TextBlindWatermarkThin(password=password)
wm_extract = text_blind_wm_new.extract(text_embed)
print('提取内容：', wm_extract)
```

## 更稳定的版本
### 张三：把隐秘消息嵌入到另一段文本中

```python
from text_blind_watermark import TextBlindWatermark

watermark = "绝密：两点老地方见！"
text = "这句话中有盲水印，你能提取出来吗？" * 16
password = "20190808"

twm = TextBlindWatermark(password=password)
twm.read_wm(watermark=watermark)
twm.read_text(text=text)
text_embed = twm.embed()

print("打上盲水印之后:")
print(text_embed)
```

显示的明文可以粘贴到任何地方

*It uses AES to encrypt*

### 李四：拿到明文，解出暗文

```python
from text_blind_watermark import TextBlindWatermark
password = "20190808"

twm_new = TextBlindWatermark(password=password)
wm_extract = twm_new.extract(text_embed)
print("解出的盲水印：")
print(wm_extract)
```
