# stegpy



    



A program for encoding information in image and audio files through steganography. Any type of data can be encoded, from raw strings to files, as shown below:



  

  



On the left, a house with a steganographically hidden image. On the right, the extracted hidden image of a cat. It is revealed by removing all but the least significant bit of each color component in the host image.

***

## Supported host formats

* PNG

* BMP

* GIF

* WebP

* WAV

Images in a different format are automatically converted to PNG. Different audio formats are not supported at all.

### Hide a message or file:

```sh

 stegpy "Hello World!" image.png

```

### Extract it:

```sh

 stegpy _image.png

```

Data is encoded without any protection by default, but it can be encrypted with the ```-p``` flag:

### Encrypt:

```sh

 stegpy "Hello World!" image.png -p

Enter password (will not be echoed):

Verify password (will not be echoed):

 stegpy _image.png -p

Enter password (will not be echoed):

Hello World!

```

### More options:

```sh

 stegpy -h

```
