# Steganodf 

This is a Python tool for hiding a secret message in a tabulated file ( e.g: CSV file ) .

It works by swapping blocks of 6 lines, each capable of storing 1 bytes ( 6! > 255 bits ) 

The dataframe is first sorted by the computed hash of each line. HMAC is also supported if you provide a password.

This method does not alter the data, but the watermark is easily sterilized.

# Installation 

```

pip install steganodf

```

# Usage 

## From command line 

```bash 

steganodf encode -i iris.csv -o iris.w.csv -m hello -p password

steganodf decode -i iris.w.csv -p password

```

## From Python

```python

import steganodf 

 

df = pd.read_csv("https://gist.githubusercontent.com/netj/8836201/raw/6f9306ad21398ea43cba4f7d537619d0e07d5ae3/iris.csv")

# Hide your message 

new_df = steganodf.encode_pandas(df, "made by steganodf", password="secret")

# Extract your message 

message = steganodf.decode_pandas(df, password="secret")

```
