I told myself I would write this tool when I had a free moment (idea
came this summer, in my hotel room @ Ubuntu Live in Portland).
CeRuLiF is a tool to hide data in plain text documents. Sure, you can
hide data in BMP, WAV, and tons of other file types that have massive
"slack space". However, I thought this would be a cool idea :-) Not
sure if anyone already wrote a tool like this already. Feel free to
clean up the code... [btw, i/o can be done via std pipes or files]
$ python cerulif.py --help
Usage: cerulif.py [options]
Options:
--version show program's version number and exit
-h, --help show this help message and exit
-i IFILE, --input-file=IFILE
input file
-m MFILE, --message-file=MFILE
message file containing secret
-o OFILE, --output-file=OFILE
output file
-z, --zip-message zlib the hidden message
-H, --hide embed a hidden message
-U, --unhide unembed a hidden message
-p, --parachute simple checks for non-cerulified input files
$ ls -s large-crlf-file.txt
1012 large-crlf-file.txt
$ echo 'setec astronomy' | python cerulif.py -i large-crlf-file.txt -H
-o /tmp/public-document.txt
$ ls -s /tmp/public-document.txt
1012 /tmp/public-document.txt
$ python cerulif.py -i /tmp/public-document.txt -U
setec astronomy
