stego is a steganographic swiss army knife.

Features

• Cross platform (MacOS, Windows, Linux)
• Encoding and decoding of images/text/binary files into audio/photo/movie files
• Fast and nearly undetectable encoding.
• Smart stdin/stdout detection (try piping to stego instead of using --txt)
• lossless decoding of data
• Simple, stateless CLI
• Zero system-dependencies (standalone binary)

⚒ Usage

```bash

Simple encoding

Encodes the message "Hello, Stego!" into the provided image

stego encode text --input image.png --output encoded-image.png --txt "Hello, Stego!"

Simple decoding

decodes and prints out the encoded message ("Hello, Stego!") hidden in the provided image

stego decode text --input encoded-image.png

Stdin detection

echo "Hello, Stego!" | stego encode text --input image.png --output encoded-image.png

Example

encodes contents of "secret" into hostimage.png and saves as output.png

cat secret | stego encode text -i hostimage.png -o output.png

decodes and prints contents of "secret"

stego decode text -i output.png

Help

stego --help stego encode --help stego decode --help ```

📦 Installation
