• 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|...}}
