Manual
Welcome to the pdf_hide wiki! This is a manual page for the command-line interface.
Please get started with the program before diving into this.
Embeds data in a PDF file, or extracts embedded data from a PDF file.
pdf_hide [-o OUTPUT_FILE] [OPTS] {embed DATA_FILE | extract} PDF_FILE
pdf_hide {-h | --help}
Prints help for the program and exits
pdf_hide CMD {-h | --help}
Prints help for CMD (embed or extract) and exits
pdf_hide --version
Prints the version of the program and exits
usage: pdf_hide [-o OUTPUT_FILE] [-k KEY] [-n NBITS] [-r RED]
[-i [--custom-range]]
[-v | -q]
{embed | m} [--no-random] DATA_FILE PDF_FILE
DATA_FILE — the binary data file to embed
PDF_FILE — the PDF file (may be compressed) to use as input
-o FILENAME, --output FILENAME — use FILENAME as the output file
-k KEY, --key KEY — use KEY as the stego-key
-i, --improve — use algo improvements
--custom-range — use data in [-450,-250] without -333 and -334 (ignored with original algo, will force --no-random, will force NBITS to maximum 6)
-v, --verbose — set verbosity level, can be counted to increase — eg -vvv
-q, --quiet — force quiet output, exclusive with -v
-n NBITS, --nbits NBITS — use NBITS as the number of bits to use for numerals
-r RED, --redundancy RED — use RED as the redundancy parameter (strictly between 0 and 1)
--no-random — do not embed random values in unused operators
usage: pdf_hide [-o OUTPUT_FILE] [-k KEY] [-n NBITS] [-r RED]
[-i [--custom-range]]
[-v | -q]
