- Extract data from a WAV audio file:
`steghide extract --stegofile {{path/to/sound.wav}}`
- Display file information, trying to detect an embedded file:
`steghide info {{path/to/file.jpg}}`
- Embed data in a JPEG image, using maximum compression:
`steghide embed --coverfile {{path/to/image.jpg}} --embedfile {{path/to/data.txt}} --compress {{9}}`
- Get the list of supported encryption algorithms and modes:
`steghide encinfo`
- Embed encrypted data in a JPEG image, e.g. with Blowfish in CBC mode:
`steghide embed --coverfile {{path/to/image.jpg}} --embedfile {{path/to/data.txt}} --encryption {{blowfish|...}} {{cbc|...}}`
