I'm not sure if it's effective steganography. It says that you can encrypt hidden files. If I use this on a file which contains an encrypted hidden file, will it detect that there is a file without giving a key? If it does it's not proper steganography. I used steghide once or twice, it claims that the existence of the datafile cannot be proven, can hide in image and audio files. It doesn't survive basic lossy compression cycles, but can hide in jpeg files.
