Install StegHide in Ubuntu

I've recently been brushing up on my Stego, and have been reading an excellent book called "Data Hiding"; highly recommended reading.

Anyway I've been installing most of the tools used in the book and have found that most of them are quite old and take a bit of work to compile. I'm making notes here, on how I've achieved the install on my host, currently Ubuntu 12.04

StegHide

You need a few dependencies here:

sudo apt-get install -y libjpeg-dev libmcrypt-dev libmhash-dev

Then you can try to compile the source; I still couldnt get it to complie, so installed a .deb from Launchpad!


wget http://launchpadlibrarian.net/5049761/steghide_0.5.1-8_amd64.deb && sudo dpkg -i steghide_0.5.1-8_amd64.deb

Try it:

steghide 
steghide version 0.5.1

the first argument must be one of the following:
 embed, --embed          embed data
 extract, --extract      extract data
 info, --info            display information about a cover- or stego-file
   info       display information about
 encinfo, --encinfo      display a list of supported encryption algorithms
 version, --version      display version information
 license, --license      display steghide's license
 help, --help            display this usage information

embedding options:
 -ef, --embedfile        select file to be embedded
   -ef        embed the file
 -cf, --coverfile        select cover-file
   -cf        embed into the file
 -p, --passphrase        specify passphrase
   -p       use to embed data
 -sf, --stegofile        select stego file
   -sf        write result to instead of cover-file
 -e, --encryption        select encryption parameters
   -e []|[]  specify an encryption algorithm and/or mode
   -e none               do not encrypt data before embedding
 -z, --compress          compress data before embedding (default)
   -z                 using level (1 best speed...9 best compression)
 -Z, --dontcompress      do not compress data before embedding
 -K, --nochecksum        do not embed crc32 checksum of embedded data
 -N, --dontembedname     do not embed the name of the original file
 -f, --force             overwrite existing files
 -q, --quiet             suppress information messages
 -v, --verbose           display detailed information

extracting options:
 -sf, --stegofile        select stego file
   -sf        extract data from
 -p, --passphrase        specify passphrase
   -p       use to extract data
 -xf, --extractfile      select file name for extracted data
   -xf        write the extracted data to
 -f, --force             overwrite existing files
 -q, --quiet             suppress information messages
 -v, --verbose           display detailed information

options for the info command:
 -p, --passphrase        specify passphrase
   -p       use to get info about embedded data

To embed emb.txt in cvr.jpg: steghide embed -cf cvr.jpg -ef emb.txt
To extract embedded data from stg.jpg: steghide extract -sf stg.jpg
