Usage

Usage: mimic [-h | -f [-m] [-e] | -r [-d] | -c [-d] | -x | -l]

Options:
  -h, --help            show this help message and exit
  -f, --forward         mimic input to output (default)
  -r, --reverse         de-mimic input to output
  -c, --check           check input for suspicious chars, flag in output
  -e SOURCE_STEG_FILE, --encode=SOURCE_STEG_FILE
                        encode this file as a hidden co-stream in output
  -d DEST_STEG_FILE, --decode=DEST_STEG_FILE
                        decode a hidden co-stream from input to this file
  -m CHANCE, --me-harder=CHANCE
                        forward replacement percent, default 1
  -x EXPLAIN_CHAR, --explain=EXPLAIN_CHAR
                        show a char's homoglyphs
  -l, --list            show all homoglyphs

Mimic is much like an old-school *nix command - it operates on pipe I/O, thus does not pay attention to files directly. To input a file, use cat; otherwise it will wait for keyboard input. Likewise, to output a file, use > or tee; otherwise it will simply print the output to the console.

Examples

These examples assume that mimic has been installed as per the instructions below. Before installation, invoke via python -m mimic.

mimic --list           # Show all of the homoglyphs
mimic --explain=o      # What crazy things can we do with this letter?
mimic --me-harder 100  # Type some lines in and mess with every single char
mimic --reverse        # Undo the mayhem. Boooring.
cat somefile | mimic   # Pipe some source through at 1%

# Turn up the knob and save the results
cat somefile | mimic --me-harder 25 > mimicked

# Find out exactly where we broke the source
cat mimicked | mimic --check | less

# Now we know the source is broken, so fix it
cat mimicked | mimic --reverse > fixedfile

# This should output nothing (i.e. the files are the same)
diff fixedfile somefile
