█▌ - STEGHIDE - CONCEAL DATA IN AUDIO OR IMAGE FILE - █▌
█▌ █▌
█ _________________________________________________________________ ▐▌
█ / Steghide is a steganography program that is able to hide data \ ▐▌
█ | in various kinds of image- and audio-files. | ▐▌
█ | Features include the compression of the embedded data, | ▐▌
█ | encryption of the embedded data and automatic integrity | ▐▌
█ | checking using a checksum. The color- respectivly | ▐▌
█ | sample-frequencies are not changed thus making the embedding | ▐▌
█ | resistant against first-order statistical tests. | ▐▌
█ | | ▐▌
█ | The JPEG, BMP, WAV and AU file formats are supported for use | ▐▌
█ | as cover file. There are no restrictions on the format of the | ▐▌
█ \ secret data." / ▐▌

█ In THIS wav file (2.9MB; download it if you want to view my hidden file) I ▐▌
█ have hidden a secret pdf file. Password is: mewbies ▐▌
█ NOTES: ▐▌
█ `````` ▐▌
█ 1. Steghide, by Stefan Hetzl, works very nicely and very easy to use. Be ▐▌
█ aware though that the 'cover file' needs to much larger than hidden ▐▌
█ file/data. If it isn't large enough you will have the error ▐▌
█ "steghide: the cover file is too short to embed the data". ▐▌
█ I don't know what the size ratio cover:hidden is (more than 31+:1 on ▐▌
█ the files I tested it with). I wish there was a command to determine ▐▌
█ size needed to encrypted it into x cover file. ▐▌
█ 2. The size of original cover file will though be the same size (at least ▐▌
█ in my test) as the encrypted cover file it creates. ▐▌
█ ▐▌
█ LINUX: ▐▌
█ `````` ▐▌
█ su ▐▌
█ aptitude install steghide ▐▌
█ exit ▐▌
█ man steghide ▐▌
█ ▐▌
█ WINDOWS: ▐▌
█ ```````` ▐▌
█ Unzip it, done. Manual is included in the zip or find on line here. ▐▌
█ Launch a command prompt window: Press the Windows logo key on your ▐▌
█ keyboard +r to launch Run, then type in the 'Open' drop down window: cmd ▐▌
█ ▐▌
█ Change to the directory containing steghide.exe; for example if it is on D ▐▌
█ drive type in and press enter: D: ▐▌
█ cd D:\Downloads\steghide\ ▐▌
█ ▐▌
█ USAGE LINUX & WINDOWS: ▐▌
█ `````````````````````` ▐▌
█ To hide a file in an audio or image file: ▐▌
█ Basic example; mooeow.wav is the cover file containing the hidden ▐▌
█ encrypted secret.pdf: ▐▌
█ steghide embed -cf mooeow.wav -ef secret.pdf ▐▌
█ To include a password in cmd line (-p mewbies) and declare name of the ▐▌
█ output file (-sf mooeow_secret.wav): ▐▌
█ steghide embed -cf mooeow.wav -ef secret.pdf -p mewbies -sf mooeow_secret.wav
█ ▐▌
█ -cf is the cover file that will become the output file ▐▌
█ -ef is the encrypted, hidden file ▐▌
█ -p is the password ▐▌
█ -sf stego file to output name to (or it will overwrite the original) ▐▌
█ ▐▌
█ To extract the embedded / hidden file: ▐▌
█ steghide extract -sf mooeow_secret.wav ▐▌
█ You'll be prompted for the password. ▐▌
█ ▐▌
█ To view information about the embedded data only: ▐▌
█ steghide info mooeow_secret.wav ▐▌
█ Or declare -p to view more information and not be prompted for pass: ▐▌
█ steghide info mooeow_secret.wav -p mewbies ▐▌
