## How to Use

install

```bash
>pip install text_blind_watermark
```

### embed message into text:

```python
from text_blind_watermark import TextBlindWatermark2

password = '20190808'
text = '这句话中有盲水印，你能提取出来吗？'
watermark = 'github.com/guofei9987'

text_blind_wm = TextBlindWatermark2(password=password)

text_with_wm = text_blind_wm.embed(text=text, watermark=watermark)
print(text_with_wm)
```


### extract message from text

```python
text_blind_wm2 = TextBlindWatermark2(password=password)
wm_extract = text_blind_wm2.extract(text_with_wm)
print('提取内容：', wm_extract)
```

>github.com/guofei9987



### `chr_type`

You can choose different type to get better performance.


```python
from text_blind_watermark import TextBlindWatermark2

password = '20190808'
text = '这句话中有盲水印，你能提取出来吗？'
watermark = 'github.com/guofei9987'

text_blind_wm = TextBlindWatermark2(password=password, chr_type=(3, 4))

text_with_wm = text_blind_wm.embed(text=text, watermark=watermark)
print(text_with_wm)

text_blind_wm2 = TextBlindWatermark2(password=password, chr_type=(3, 4))
wm_extract = text_blind_wm2.extract(text_with_wm)
print('提取内容：', wm_extract)
assert watermark == wm_extract
```

## Another algorithm is more robust

### Alice Put her text watermark into a text:

```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)
```

Then, you can paste this text to where you need.



### Bob Extract the invisible watermark

```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)
```
