Steghide is steganography program. This tool helps us to see if any file is obscured in under image file. It also allow us to embedd file into image.
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 <filename> display information about <filename>
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 <filename> embed the file <filename>
-cf, --coverfile select cover-file
-cf <filename> embed into the file <filename>
-p, --passphrase specify passphrase
-p <passphrase> use <passphrase> to embed data
-sf, --stegofile select stego file
-sf <filename> write result to <filename> instead of cover-file
-e, --encryption select encryption parameters
-e <a>[<m>]|<m>[<a>] specify an encryption algorithm and/or mode
-e none do not encrypt data before embedding
-z, --compress compress data before embedding (default)
-z <l> using level <l> (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 <filename> extract data from <filename>
-p, --passphrase specify passphrase
-p <passphrase> use <passphrase> to extract data
-xf, --extractfile select file name for extracted data
-xf <filename> write the extracted data to <filename>
-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 <passphrase> use <passphrase> to get info about embedded data
Examples : 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
