There can be information in an image while this tool is not able to find anything. Also, other tools might not be able to extract information from encrypted images created by this tool.

Steganography relies on the latent noise-to-signal ratio of the analogue source material. The "least significant" bits (actual bits will depend on codec) are overwritten by an encrypted stream of secondary "stego" bits such that the primary public content of the image is not destroyed or distorted with notable artefacts. 2019-07-12 · July 12, 2019.
